Introducing a scansion machine for Dutch poetry and prose, Una máquina de escansión para poesía y prosa en neerlandés

Repositorio: Loquens
van Oostendorp, Marc

This paper looks into the possibility that the rhythm present in poetry is the same that characterizes natural languages. This hypothesis, although attractive, faces serious problems such as the tremendous amount of data necessary to reach any valid conclusion and the fact that certain poetic traditions may deviate from the rhythm expected in a certain language. In order to tentatively test whether there is a relationship between the rhythmic properties of a certain language and its poetry we…, En este artículo examinamos la posibilidad de que el ritmo presente en la poesía sea el mismo que caracteriza a las lenguas naturales. Esta hipótesis, aunque atractiva, se enfrenta a importantes problemas, tales como la necesidad de disponer de una ingente cantidad de datos para así obtener conclusiones válidas, o el hecho de que ciertas tradiciones poéticas pueden desviarse del ritmo esperado en una determinada lengua. Con el fin de examinar provisionalmente si existe una relación entre las…



Review of spoken dialogue systems, Sistemas de diálogo: una revisión

Repositorio: Loquens
López-Cózar, Ramón, Callejas, Zoraida, Griol, David, Quesada, José F.

Spoken dialogue systems are computer programs developed to interact with users employing speech in order to provide them with specific automated services. The interaction is carried out by means of dialogue turns, which in many studies available in the literature, researchers aim to make as similar as possible to those between humans in terms of naturalness, intelligence and affective content. In this paper we describe the fundaments of these systems including the main technologies employed…, Los sistemas de diálogo son programas de ordenador desarrollados para interaccionar con los usuarios mediante habla, con la finalidad de proporcionarles servicios automatizados. La interacción se lleva a cabo mediante turnos de un tipo de diálogo que, en muchos estudios existentes en la literatura, los investigadores intentan que se parezca lo más posible al diálogo real que se lleva a cabo entre las personas en lo que se refiere a naturalidad, inteligencia y contenido afectivo. En este…

Repositorio: Loquens
Vanrell, María del Mar, Ballone, Francesc, Schirru, Carlo, Prieto, Pilar

In this paper we investigate the interplay between lexicon, syntax, intonation and pragmatics in Sardinian polar questions. To this end, a production study was designed to elicit polar questions with different bias and polarity conditions by means of the Discourse Completion Task Methodology. The resulting data were then prosodically and syntactically annotated using Praat. The results can be summarized as follows. Regarding lexico-syntactic markers, the particle a functions as a mitigator or…, Este artículo investiga la interacción entre sintaxis, entonación, pragmática y partículas interrogativas en las preguntas absolutas del sardo. Con tal propósito, se diseñó un experimento de producción mediante la metodología de la Tarea de Compleción del Discurso que permite obtener interrogativas absolutas en diferentes condiciones de sesgo y polaridad. Los datos se analizaron prosódica y sintácticamente mediante el programa Praat. Los resultados se pueden resumir como sigue: en relación con…



Different distributions of contrastive vowel nasalization in Basque, Diferentes distribuciones de la nasalización vocálica contrastiva en vasco

Repositorio: Loquens
Egurtzegi, Ander

Contrastive vowel nasalization is usually a consequence of the reinterpretation of the phonetic nasalization of a vowel due to coarticulation with an adjacent nasal consonant as originating in the vowel itself. Basque developed contrastive vowel nasalization after the loss of the nasalized laryngeal /?./ (from older intervocalic *n). This loss did not occur under the same circumstances in all dialects, and thus yielded different distributions of contrastive nasalization. This paper discusses…, La nasalización vocálica contrastiva es habitualmente consecuencia de la reinterpretación de la nasalización fonética de una vocal debida a la coarticulación con una consonante nasal adyacente como si esta se originase en la propia vocal. El euskera desarrolló nasalización vocálica contrastiva tras la pérdida de la laringal nasalizada /?./ (de antigua *n intervocálica). Esta pérdida no ocurrió en los mismos contextos en todos los dialectos y, por lo tanto, dio lugar a diferentes distribuciones…



Automatic speaker recognition of spanish siblings: (monozygotic and dizygotic) twins and non-twin brothers, Reconocimiento automático de locutor con hermanos españoles: hermanos gemelos (monozigóticos y dizigóticos) y no gemelos

Repositorio: Loquens
San Segundo, Eugenia, Künzel, Hermann

The performance of the automatic speaker recognition (ASR) system BatvoxTM (Version 4.1) has been tested with a male population of 24 monozygotic (MZ) twins, 10 dizygotic (DZ) twins, 8 non-twin siblings and 12 unrelated speakers (aged 18–52 with Standard Peninsular Spanish as their mother tongue). Since the cepstral features in which this ASR system is based depend largely on anatomical–physiological foundations, we hypothesized that such features ought to be gene-dependent. Therefore, higher…, Hemos utilizado el sistema de reconocimiento automático BatvoxTM (versión 4.1) con una población de hablantes masculinos compuesta de 24 gemelos monocigóticos, 10 gemelos dicigóticos, 8 hermanos no gemelares y 12 hablantes no emparentados (edades comprendidas entre 18 y 52 años, con español centropeninsular como lengua materna). Puesto que los parámetros cepstrales en los que se basa BatvoxTM dependen en gran medida de las bases anatómicas y fisiológicas del tracto vocal del hablante, se…



The role of gesture duration in the initial unstressed vowel shift in Galician. A first approximation, Importancia de la duración gestual en el cambio de las vocales iniciales átonas del gallego: una primera aproximación

Repositorio: Loquens
Aguete Cajiao, Alba

This study examines a change in the Galician vowel system. This change has been described as the phonologization of the distinction between low‑mid-low and mid-high vowels of Galician in unstressed pretonic position. The principal aim of this study is to test whether this distinction can be triggered by the longer duration of those initial vowels, favoured by the structure of the syllable and by the initial prosodic position. To verify this hypothesis, an articulatory simulation study with TADA…, Este estudio examina un cambio producido en el vocalismo gallego. Este cambio ha sido descrito recientemente como la fonologización de la distinción entre las vocales medias-bajas y mediasaltas del gallego en posición átona pretónica. El objetivo principal de este estudio es comprobar si esta distinción puede ser debida a una mayor duración de las vocales en inicio de palabra, propiciada por la estructura de la sílaba y por la posición de inicio de límite prosódico. Con el fin de comprobar la…

Biomedical applications of voice and speech processing, Aplicaciones biomédicas del procesamiento de la voz y el habla

Repositorio: Loquens
Gómez Vilda, Pedro

Neurological deterioration presents different variants depending on their classification criterion, which may be their anatomic localization or their disease clinical features, although there is not a clear cut between both. Anatomically this ample group of disorders may affect the central nervous system (brain and spinal cord), or the peripheral nervous system. Clinically, the neurodegenerative disorders are classified as affecting cognitive functions or neuromotor capabilities. In the group…, El deterioro neurológico presenta diferentes variantes, dependiendo del criterio de clasificación que se emplee, que puede ser o bien su localización anatómica, o bien sus rasgos clínicos, aunque no existe una frontera clara entre ambos. Desde el punto de vista anatómico, los trastornos de este tipo pueden afectar ya sea al sistema nervioso central (cerebro y médula espinal), ya sea al sistema nervioso periférico. Desde el punto de vista clínico, se clasifican como de tipo cognitivo o de tipo…



Monitoring Parkinson Disease from speech articulation kinematics, Monitorización de la enfermedad de Parkinson a partir de la cinemática de la articulación del habla

Repositorio: Loquens
Gómez, Pedro, Mekyska, Jiri, Gómez, Andrés, Palacios, Daniel, Rodellar, Victoria, Álvarez, Agustín

Parkinson Disease (PD) is a neuromotor illness affecting general movements of different muscles, those implied in speech production being among them. The relevance of speech in monitoring illness progression has been documented in these last two decades. Most of the studies have concentrated in dysarthria and dysphonia induced by the syndrome. The present work is devoted to explore how PD affects the dynamic behavior of the speech neuromotor biomechanics (neuromechanics) involved in deficient…, La enfermedad de Parkinson (EP) es un trastorno del sistema neuromotor que afecta a todo tipo de movimientos regulados por el sistema muscular humano, entre ellos los que controlan la producción del habla. La importancia del habla en la monitorización del progreso de la EP se ha estudiado ampliamente durante las últimas dos décadas. La mayoría de los estudios se han concentrado en describir y modelar el comportamiento de la fonación (disfonía) y de la articulación (disartria), en relación con…

An attribute detection based approach to automatic speech processing, Una estrategia de procesamiento automático del habla basada en la detección de atributos

Repositorio: Loquens
Siniscalchi, Sabato Marco, Lee, Chin-Hui

State-of-the-art automatic speech and speaker recognition systems are often built with a pattern matching framework that has proven to achieve low recognition error rates for a variety of resource-rich tasks when the volume of speech and text examples to build statistical acoustic and language models is plentiful, and the speaker, acoustics and language conditions follow a rigid protocol. However, because of the “blackbox” top-down knowledge integration approach, such systems cannot easily…, Los sistemas más novedosos de reconocimiento automático de habla y de locutor suelen basarse en un sistema de coincidencia de patrones. Gracias a este modo de trabajo, se han obtenido unos bajos índices de error de reconocimiento para una variedad de tareas ricas en recursos, cuando se aporta una cantidad abundante de ejemplos de habla y texto para el entrenamiento estadístico de los modelos acústicos y de lenguaje, y siempre que el locutor y las condiciones acústicas y lingüísticas sigan un…



What is computational phonology?, ¿Qué es la fonología computacional?

Repositorio: Loquens
Daland, Robert

Computational phonology is not one thing. Rather, it is an umbrella term which may refer to work on formal language theory, computer-implemented models of cognitive processes, and corpus methods derived from the literature on natural language processing (NLP). This article gives an overview of these distinct areas, identifying commonalities and differences in the goals of each area, as well as highlighting recent results of interest. The overview is necessarily brief and subjective. Broadly…, La fonología computacional no representa un campo unitario, sino que es un término genérico que puede hacer referencia a obras sobre teorías de lenguajes formales; a modelos de procesos cognitivos implementados por ordenador; y a métodos de trabajo con corpus, derivados de la bibliografía sobre procesamiento del lenguaje natural (PLN). Este artículo ofrece una visión de conjunto de estas distintas áreas, identifica los puntos comunes y las diferencias en los objetivos de cada una, y pone de…



Listeners may rely on intonation to distinguish languages of different rhythm classes, Los oyentes podrían basarse en la entonación para distinguir lenguas de diferentes clases rítmicas

Repositorio: Loquens
Hagmann, Lea, Dellwo, Volker

Previous research argued that listeners can distinguish between languages of different rhythm class but not of the same class (class discrimination hypothesis). In the present research we tested the role of duration and pitch cues (intonation) in this process. In Experiment I we tested whether we could replicate previous findings on listeners’ language discrimination ability with native Swiss German listeners. Results showed that the discrimination of English and Japanese based on durational…, Algunas investigaciones anteriores sostienen que los oyentes pueden distinguir entre lenguas de diferente ritmo pero, en cambio, no de la misma clase rítmica (hipótesis de la discriminación de clases). En la presente investigación examinamos el papel de la duración y de las claves tonales (entonación) en este proceso. En el Experimento I analizamos si podíamos replicar los resultados anteriores sobre la capacidad de discriminación lingüistica de los oyentes con jueces nativos de alemán de Suiza…



Syntax and word-specific phonetics: the origins of the allomorphs of the Galician definite article, Sintaxis y fonética particular de ciertas palabras: Orígenes de los alomorfos del artículo definido en gallego

Repositorio: Loquens
Dubert-García, Francisco

The Galician definite article seems to be a case of a ditropic clitic which, phonologically, attaches to the preceding word while maintaining direct, constitutive syntactic relations with following words. The article has three allomorphs whose selection is conditioned by the ending of the preceding word. In this paper I study the historical origins of these allomorphs. They are the result of assimilatory processes due to constraints governing the structure of the syllable and intersyllabic…, El artículo definido gallego parece ser un clítico ditrópico: se liga fonológicamente a la palabra que le antecede, aunque mantiene relaciones constitutivas directas con las palabras que le siguen. Tiene tres alomorfos cuya distribución está condicionada por el segmento final de la palabra que lo precede. En este trabajo estudio los orígenes históricos de estos tres alomorfos, que son el resultado de procesos asimilatorios debidos a las restricciones que gobiernan la estructura de la sílaba y…



A stochastic approach to rhotic variation in Spanish codas, Análisis estocástico de la variación de las róticas en posición de coda en español

Repositorio: Loquens
Gibson, Mark

A stochastic analysis using aerodynamic and temporal variables is presented to explain tap/trill variation in Spanish codas. Simultaneous intraoral pressure (Po), translingual flow (F) and acoustic signals were obtained for two native speakers of Peninsular Spanish performing a rate-controlled reiterative task. Data were analyzed using linear mixed effects models fitted with random effects for speaker and repetition. The results show that tongue height and tongue anteriority of the preceding…, Se presenta un análisis estocástico con variables aerodinámicas y temporales para explicar la variación de las róticas en posición implosiva en español. Las señales acústicas, de presión orofaríngea y flujo traslingual, fueron obtenidas simultáneamente de dos sujetos nativos de habla hispana en una tarea de repetición controlada. Los datos fueron analizados utilizando una serie de modelos lineales de efectos mixtos tomando como efectos aleatorios programados tanto la variable hablante como…



Accent mark and visual word recognition in Spanish, Marca acentual y reconocimiento visual de palabras en español

Repositorio: Loquens
Schwab, Sandra

The present research aims at determining to what extent an orthographic error related to the accent mark affects the visual recognition of Spanish words. For this, we conducted two experiments of visual lexical decision (with no word production), in which Spanish-speaking participants were instructed to ignore the presence or the absence of the accent mark. Stimuli were composed of words originally without accent mark (OrNA for ‘originally no accent’; Experiment 1) and words originally with an…, Esta investigación tiene como meta determinar en qué medida un error ortográfico relativo al acento gráfico (i.e., tilde) afecta al reconocimiento visual de las palabras en español. Para ello, realizamos dos experimentos de decisión léxica visual (sin producción de las palabras), en los que los participantes tenían que ignorar la presencia o ausencia del acento gráfico. Los estímulos se componían de palabras originalmente sin acento gráfico (OrNA para ‘originally no accent’; Experimento 1) y…



Tinnitus: mechanisms, measures and sound treatments, Acúfenos: mecanismos, medidas y tratamientos sonoros

Repositorio: Loquens
Cobo Parra, Pedro

Tinnitus is the auditory perception of sounds in the absence of any external source. Tinnitus that occurs every day for more than five minutes is reported by 10–15% of the population, and for 1 to 2% it is a handicap that interferes significantly with their quality of life (severe tinnitus). Despite the intensive research into therapeutic options, including surgery, pharmacotherapy, and electrical and acoustical stimulation, there is no approved treatment for tinnitus at present. Although the…, El acúfeno consiste en la percepción de un sonido fantasma (un zumbido continuo dentro de la cabeza), sin una fuente externa que lo produzca. Para apreciar la importancia del tema hay que tener en cuenta que aproximadamente un 1-2 % de la población padece de acúfeno severo, y que a día de hoy no existe ninguna medicina que lo cure. Todavía no se conoce el origen exacto del acúfeno, aunque se supone que se produce por un mecanismo de compensación homeostático del sistema auditivo central ante…

Repositorio: Loquens
Martínez-Paricio, Violeta, Kager, René

This article presents a reanalysis of the foot-based phonology of Chugach Alutiiq (henceforth CA), a language that displays a complex mixed ternary–binary rhythm, as well as metrically conditioned distributions of pitch, fortition and vowel lengthening. Elaborating on earlier analyses of CA that had posited some kind of ternary constituent (Hewitt, 1991, 1992; Leer, 1985a, 1985b, 1985c; Rice, 1992), we propose CA should be analyzed by means of the Internally Layered Ternary (ILT) foot, a…, Este artículo presenta un reanálisis de diversos aspectos fonológicos de la lengua esquimal Chugach Alutiiq (de ahora en adelante, CA): la asignación de acentos rítmicos (binarios y ternarios), la distribución de los tonos alto y bajo, el fortalecimiento de algunas consonantes y el alargamiento de determinadas vocales. Influidos por análisis previos de la lengua que postularon la existencia de algún tipo de constituyente prosódico ternario en CA (Hewitt, 1991, 1992; Leer 1985a, 1985b, 1985c;…

Typological variation in the phonetic realization of lexical and phrasal stress: Southern British English vs. Tunisian Arabic, Variación tipológica en la realización fonética del acento léxico y del acento de frase: contraste entre el inglés británico del sur y el árabe tunecino

Repositorio: Loquens
Bouchhioua, Nadia

Results of phonetic experiments on the acoustic correlates of lexical stress (word-level prominence) and phrasal stress (phrase-level prominence = accent) as two separate concepts in two typologically different languages, Southern British English (SBE) and Tunisian Arabic (TA), are reported in this study. Because of the confusion in the literature between the terms stress and accent, their acoustic correlates were muddled, too. To avoid this confusion, the data in this study are elicited using…, Este artículo describe los correlatos acústicos del acento léxico (prominencia dentro de la palabra) y del acento de frase (prominencia dentro de la frase), como dos conceptos diferentes, en dos lenguas tipológicamente dispares: el inglés británico del sur y el árabe tunecino. En la bibliografía se observa cierta indistinción entre los términos acento [léxico] (en inglés, stress) y acento [de frase] (en inglés, accent), de modo que también sus correlatos acústicos aparecen entremezclados.

Repositorio: Loquens
Troncoso-Ruiz, Aurora, Elordieta, Gorka

This study investigates the convergent accommodating behaviour of Andalusian speakers (Southern Spain) relocated in Asturias (Northern Spain), a context of dialect contact, in terms of intonation. We aim to address three research questions: (1) is there evidence for accommodation? (2) Do social factors determine accommodation? And (3) does salience predict which prosodic features are more likely to be adopted by relocated speakers? We elaborated a corpus of spontaneous speech including an…, Este estudio investiga acomodación convergente en hablantes de castellano de Andalucía que se han mudado a Asturias, un contexto de contacto de dialectos, en términos prosódicos. Abordamos tres preguntas de investigación: 1) ¿existen evidencias de acomodación en estos hablantes?; 2) ¿está determinado el comportamiento acomodante por factores sociales?, y 3) ¿puede la prominencia predecir qué rasgos prosódicos adoptarán los hablantes reubicados?

Ghaffarvand Mokari, Payam, Werner, Stefan

This study investigates the use of different cues in discrimination of Azerbaijani /oe/ and /ɯ/ vowels. Regarding the large overlap in f1-f2 vowel space in the production of these vowels, this study researched for other possible cues in their categorization. Twenty native Azerbaijani listeners were tested through a perceptual identification test. Since f2 was weighted more consistently through the experiment, it is suggested that f2 is the primary cue in discriminating of this vowel pair. We…, Este estudio investiga el uso de diferentes claves en la discriminación de las vocales /œ/ y /ɯ/ del azerbaiyano. Teniendo en cuenta el considerable solapamiento que en la producción de estas vocales se produce en el espacio vocálico de f1–f2, en este estudio se han investigado otras posibles claves en su categorización. Veinte oyentes, hablantes nativos de azerbaiyano, participaron en un test perceptivo de identificación. Puesto que se otorgó a f2 un peso más consistente a lo largo del…

Repositorio: Loquens
Pedemonte, Marisa, Díaz, Marcela, Medina-Ferret, Eduardo, Testa, Martín

It is known that auditory information is continuously processed both during wakefulness and sleep. Consistently, it has been shown that sound stimulation mimicking tinnitus during sleep decreases the intensity of tinnitus and improves the patients’ quality of life. The mechanisms underlying this effect are not known. To begin to address this question, eleven patients suffering from tinnitus were stimulated with sound mimicking tinnitus at different sleep stages; 4 were stimulated in N2, 4 in…, Es sabido que la información auditiva se procesa continuamente durante la vigilia y el sueño. Se ha demostrado que la estimulación con sonido que imita el tinnitus, aplicada durante el sueño, disminuye la intensidad del tinnitus y mejora la calidad de vida de los pacientes. Los mecanismos que subyacen a esta mejoría no se conocen, aunque en la etapa de sueño con husos (N2) fueron demostrados los principales cambios en los espectros de potencia y la coherencia en las ondas…

Repositorio: Loquens
Cuesta, María, Cobo, Pedro

Although tinnitus, the conscious perception of a sound without a sound source external or internal to the body, is highly correlated with hearing loss, the precise nature of such correlation remains still unknown. People with high pitch tinnitus are used to suffer from high frequency hearing losses, and vice versa, low pitch tinnitus is mostly associated with low frequency hearing losses. However, many subjects with low or high frequency losses do no develop tinnitus. Thus, studies trying to…, Aunque el acúfeno, la percepción consciente de un sonido en ausencia de una fuente externa o interna, está altamente correlacionada con las pérdidas auditivas, aún no se conoce la naturaleza precisa de esta relación. Las personas con acúfeno de alta frecuencia suelen tener pérdidas auditivas de alta frecuencia, y viceversa, cuando el acúfeno percibido es de baja frecuencia, las pérdidas auditivas también afectan a la parte de baja frecuencia del espectro auditivo. Sin embargo, hay muchas…

The smoothed cepstral peak prominence (CPPS) is an acoustic measure that can be calculated in both sustained vowels and continuous speech. The goal of this work is to find out the diagnostic accuracy of CPPS in the detection of dysphonia in Spanish. In this study 136 subjects with dysphonia and 47 healthy subjects participated. For each subject a sustained vowel and the reading of three phonetically balanced sentences were recorded. The CPPS was calculated with Praat using its default…, Los parámetros derivados de la métrica cepstral son cada vez más utilizados en la evaluación acústica de la voz, ya sea como medidas únicas o como parte de índices multivariados. El pico cepstral de mayor prominencia en el cepstrum suavizado (CPPS) ha demostrado en multitud de estudios ser la única medida acústica con la suficiente validez concurrente en la evaluación de la severidad de las alteraciones de la voz tanto en muestras de vocal sostenida como en muestras de habla continua.

Oral and written productions of language seem to correspond to ontologically separate entities. In this paper, we shall not argue against this basic assumption. However, it will be proposed that a careful examination of the writing systems and of particular written productions can provide phonologists with important information about the nature of phonological representations. Writing systems often originate in relevant intuitions about the nature of phonological units and phenomena and…, Las producciones lingüísticas orales y las escritas corresponden a entidades ontológicamente diferentes. En este artículo no presentaremos argumentos en contra de esta asunción básica. Sin embargo, se propondrá que un examen minucioso de los sistemas de escritura y de determinadas producciones escritas puede proporcionar a los fonólogos información relevante acerca de la naturaleza de las representaciones fonológicas. Los sistemas de escritura se originan a menudo a partir de valiosas…



The effect of healthy aging on within-speaker rhythmic variability: A case study on Noam Chomsky, El efecto del envejecimiento saludable en la variabilidad rítmica intra-hablante: Un ejemplo de estudio con Noam Chomsky

Repositorio: Loquens
Pellegrino, Elisa

Speech rhythm varies noticeably from language to language, and within the same language as a function of numerous linguistic, prosodic and speaker-dependent factors, among which is the speaker’s age. Cross-sectional studies comparing the acoustic characteristics of young and old voices have documented that healthy aging affects speech rhythm variability. This kind of studies, however, presents one fundamental limitation: They group together people with different life experiences, healthy…, Las propiedades rítmicas de un lenguaje varían enormemente entre variedades, así como dentro de una misma variedad en función de numerosos factores lingüísticos, prosódicos y factores dependientes del hablante, entre los cuales se encuentra la edad. Estudios transversales que comparan las características acústicas de voces jóvenes y de avanzada edad han documentado asimismo el efecto de la edad del locutor sobre la variabilidad rítmica del habla. Este tipo de estudios, sin embargo, presentan…



Is there an interlanguage intelligibility benefit in perception of English word stress?, ¿Existe un beneficio de inteligibilidad por interlengua en la percepción del acento tónico?

Repositorio: Loquens
Almbark, Rana, Bouchhioua, Nadia, Hellmuth, Sam

This paper asks whether there is an ‘interlanguage intelligibility benefit’ in perception of word-stress, as has been reported for global sentence recognition. L1 English listeners, and L2 English listeners who are L1 speakers of Arabic dialects from Jordan and Egypt, performed a binary forced-choice identification task on English near-minimal pairs (such as[ˈɒbdʒɛkt] ~ [əbˈdʒɛkt]) produced by an L1 English speaker, and two L2 English speakers from Jordan and Egypt respectively. The results…, Este trabajo pregunta si existe un “beneficio de inteligibilidad por interlengua” (‘interlanguage intelligibility benefit’) en la percepción del acento tónico, como se ha reportado para el reconocimiento global de oraciones. El estudio involucró a un grupo de oyentes de inglés como primera lengua (L1), y a oyentes nativos de dialectos árabes de Jordania y Egipto que utilizan inglés como segunda lengua (L2), quienes participaron como jueces perceptivos en una tarea de identificación de respuesta…



Rule Interaction Conversion Operations, Operaciones de conversión de interacciones de reglas

Repositorio: Loquens
Baković, Eric, Blumenfeld, Lev

Different types of interactions between pairs of phonological rules can be converted into one another using three formal operations that we discuss in this article. One of these conversion operations, rule re-ordering (here called swapping), is well-known; another, flipping, is a more recent finding (Hein et al., 2014). We introduce a third conversion operation that we call cropping. Formal relationships among the members of the set of rule interactions, expanded by cropping beyond the…, En este artículo discutimos tres operaciones formales que pueden utilizarse para subsumir en uno solo diversos tipos de interacciones entre pares de reglas fonológicas. Una de estas operaciones de conversión, la reordenación de reglas (aquí denominada swapping), es bien conocida; otra, llamada aquí flipping, es un hallazgo más reciente (Hein et al., 2014). Introducimos una tercera operación de conversión a la que le hemos dado el nombre de cropping. Se identifican y clarifican las relaciones…

Geminate blockage in Logoori harmony with no added machinery, Análisis sin mecanismos complementarios del bloqueo de la armonía mediante geminadas en Logoori

Repositorio: Loquens
Odden, David

Following the demise of the SPE theory of phonology, little attention was paid to how rules should be formulated. Instead, there was a general trend to minimize the language-specific component of a grammar, to factor out recurring patterns and state them as independent constraints or parameters. The richer representations of autose­gmental phonology additionally led to uncertainty in rule formulation, primarily because of questions about what the correct representations are, but also because…, A partir del declive de la teoría fonológica de SPE, se prestó poca atención a cómo se deberían formular las reglas. Existía, en cambio, una tendencia general a minimizar el componente gramatical específico de una lengua para fac­torizar los patrones recurrentes y establecerlos como restricciones o parámetros independientes. Las representaciones, más ricas, de la fonología autosegmental generaron además dudas sobre cuál había de ser la formulación de reglas, principalmente por los interrogantes…



Analyzing interspeaker variation in Maay, Análisis de la variación interhablante en maay

Repositorio: Loquens
Paster, Mary

This paper advocates an approach to interspeaker linguistic variation that aligns with the ‘I-language’ view (Chomsky, 1986). On this view, the object of study in linguistics is mental grammar; language is understood as being internal to the individual, in contrast to the ‘E-language’ approach, where language is external to individual speakers. This paper considers a case study from Maay (a Cushitic language spoken in southern Somalia) in which interspeaker variation in a refugee community…, El presente estudio propugna un enfoque de la variación lingüística inter-hablante acorde con la perspectiva de la ‘lengua-I’ (Chomsky, 1986). Según esta última, el objeto de estudio de la lingüística es la gramática mental; se considera que el individuo tiene interiorizado el lenguaje, al contrario de lo que defiende el enfoque de la ‘lengua-E’, en el que el lenguaje es externo a los hablantes individuales. En este artículo se estudia el caso del maay (lengua cusita hablada en el sur de…



Sets, rules and natural classes: [ ] vs. { }, Conjuntos, reglas y clases naturales: [ ] frente a { }

Repositorio: Loquens
Bale, Alan, Reiss, Charles, Ta-Chun Shen, David

We discuss a set-theoretic treatment of segments as sets of valued features and of natural classes as intensionally defined sets of sets of valued features. In this system, the empty set { } corresponds to a completely underspecified segment, and the natural class [ ] corresponds to the set of all segments, making a feature ± Segment unnecessary. We use unification, a partial operation on sets, to implement feature-filling processes, and we combine unification with set subtraction to implement…, Discutimos en este trabajo el tratamiento teórico conjunto de los segmentos entendidos como agrupaciones de rasgos especificados, y de las clases naturales entendidas como agrupaciones definidas intensionalmente de grupos de rasgos especificados. En este sistema, el conjunto vacío { } se corresponde con un segmento completamente inespecificado, y la clase natural [ ] se corresponde con el conjunto de todos los segmentos, lo que hace innecesario el rasgo ± Segmento. Nos servimos de la…

Repositorio: Loquens
Hale, Mark, Kissock, Madelyn

Recent trends in infant (and adult) speech perception studies, especially in the psychological literature where much of the speech perception work is being and has been done, shows a growing focus on more integrated perception-production-sensorimotor (PPS) bases for perception (Werker & Gervain 2013). We look here at whether the results of such studies are significant for theoretical linguistics – specifically for the fundamental question of how the linguistic system is acquired. We…, Las tendencias recientes en los estudios de percepción del habla infantil (y adulta), especialmente en la bibliografía de carácter psicológico en la que se ha enmarcado y se sigue enmarcando gran parte del trabajo sobre la percepción del habla, apuntan cada vez más hacia unas bases más integradas perceptivo-productivo-sensorimotoras (PPS) para la percepción (Werker & Gervain, 2013).

This paper reviews current experimental approaches to sound change. An ongoing challenge in sound change research is to link the initiation of sound change within individual cognitive grammars to the diffusion of novel variants through the community. The articulatory and perceptual phonetic forces that bring about the pre-conditions for sound change and that explain its directionality are always present in the transmission of spoken language, yet sound systems are remarkably stable over time.…, El presente artículo analiza los actuales enfoques experimentales del cambio fonético. Un problema recurrente en la investigación del cambio fonético es vincular la iniciación del cambio fonético en la gramática cognitiva de un individuo con la difusión de nuevas variantes en la comunidad de habla.

Repositorio: Loquens
Kreiman, Jody, Gerratt, Bruce R., Garellek, Marc, Samlan, Robin, Zhang, Zhaoyan

At present, two important questions about voice remain unanswered: When voice quality changes, what physiological alteration caused this change, and if a change to the voice production system occurs, what change in perceived quality can be expected? We argue that these questions can only be answered by an integrated model of voice linking production and perception, and we describe steps towards the development of such a model. Preliminary evidence in support of this approach is also presented.…, En la actualidad quedan por contestar dos cuestiones importantes relacionadas con la voz, a saber: (1) cuando la cualidad de la voz cambia, ¿qué alteración en el mecanismo vocal es la responsable?; y (2) si se produce un cambio en el sistema de producción de la voz, ¿qué cambio puede esperarse en la cualidad de voz percibida auditivamente? Sostenemos que la única respuesta posible a estas preguntas reside en un modelo de voz integrado que una producción y percepción, y describimos pasos hacia…

Automatic Speaker Recognition systems show interesting properties, such as speed of processing or repeatability of results, in contrast to speaker recognition by humans. But they will be usable just if they are reliable. Testability, or the ability to extensively evaluate the goodness of the speaker detector decisions, becomes then critical. In the last 20 years, the US National Institute of Standards and Technology (NIST) has organized, providing the proper speech data and evaluation protocols…, Los sistemas automáticos de reconocimiento de locutor son críticos para la organización, etiquetado, gestión y toma de decisiones sobre grandes bases de datos de voces de diferentes locutores.

Moreno Suárez, Ana Isabel, Ager Vázquez, Francisco José, Rodríguez Segovia, Constanza, Gómez Morón, Auxiliadora, Chaves Tristán, Francisca, Scrivano, Simona, Gómez Tubío, Blanca, Pliego Vázquez, Ruth

Archeological pieces with high Ag concentrations often have a surface enrichment of Ag. Usually, researchers in this field do not agree on the causes of these enrichments, one of which could be the cleaning procedures. In this work, a set of 18 ancient Greek silver coins was selected to study the effects of different cleaning procedures in terms of producing a surface Ag enrichment. The aim of this study is to find and select the less aggressive one in terms of the lower modification of Ag…

Archaeological silver–copper alloys are usually affected by silver enrichment of the near surface layers, either intentional or fortuitous. In previous studies we have shown that surface composition of archaeological bronzes and leaded copper coins obtained by XRF can be corrected by means of gamma-ray transmission (GRT) to obtain the bulk composition. In the present work, we have studied the applicability of this method to silver–copper alloys and established the most suitable conditions for…

The equids represented in cave art and current horses: a proposal to determine morphological differences and similarities

Repositorio: Repositorio de Activos Digitales del IAPH
Bernáldez Sánchez, Eloísa, García-Viñas, Esteban

Inglés: The horse is one of the species most represented in cave art during the Paleolithic in the southwest of Europe. These representations show an equine with phenotypical characteristics close to two present-day species which are considered as ancient horses: tarpans (Equus ferus caballus Linnaeus, 1758) and Pzrewalski (Equus caballus przewalskii Poliakov, 1881) horses. There are no paleontological evidence at sites dating from the Upper Paleolithic in this area of the last species, and…

Inglés: The “Cruz del Negro” necropolis in Carmona (Seville) is part of an archaeological site considered by some authors to be a Phoenician settlement. Findings from the paleobiological and taphonomic study conducted on the grave goods found in 38 funerary structures provide possible evidence to support this theory (along with other archaeological objects found there). Analysis of the animal remains found indicates three kinds of grave goods according to the animal species and anatomical parts…

There is the tendency to assume that endangered species have been both genetically and demographically healthier in the past, so that any genetic erosion observed today was caused by their recent decline. The Iberian lynx (Lynx pardinus) suffered a dramatic and continuous decline during the 20th century, and now shows extremely low genome- and species-wide genetic diversity among other signs of genomic erosion. We analyze ancient (N = 10), historical (N = 245), and contemporary (N = 172)…
