Our interest in vocal communication originally comes from the wish to better understand the role of vocal communication for speech and language processing in hearing impairment. The aim of this workshop is to provide a platform for researchers in human and non-human communication to share theoretical issues, new findings, methodologies, and tools. We also hope to stimulate lively discussions about possible extensions to other research fields, clinical applications (better diagnostics and training in hearing impairment), and technological applications (human-computer interaction, better hearing devices).
