The IAEAV dataset contains a collection of audio recordings in Spanish, comprising dialogues between medical practitioners and Alzheimer patients or healthy control participants The dataset is designed for research on speech patterns and communication dynamics, with a particular focus on Alzheimer's disease. It includes 184 recordings from healthy controls and 39 from Alzheimer patients, each annotated with time-stamped labels that differentiate between medical practitioners, patients, and overlapping speech. All audio recordings have been anonymized through morphing and the removal of personally identifiable information to ensure participant privacy. The IAEAV dataset serves as a valuable resource for studies in artificial intelligence, natural language processing for speech processing and text transcriptions, clinical interaction analysis, and Alzheimer's research, offering insights into verbal communication in both clinical and control settings.
