Clinical phonetics

Sounds produced for communication purposes carry many elements which are irrelevant to the content of language production, but are instead related to various aspects of the speaker’s behaviour and state, and may therefore be indicators of illnesses. A Joint Research Action (ARC) project is dedicated to the development of voice-based measurement tools which provide objective information on disabled people in very diverse contexts and clinical situations. These tools have been reinvested in another ARC project, aimed at targeting vocal indicators of stress, cognitive load and fatigue in relation to variations in the biochemistry of the speaker. Aeronautics is the project’s most researched domain.
