Clinical phonetics, atypical voice and speech

Another key theme at the LPP is “T2 - Clinical phonetics, atypical voice and speech”, which focuses on the dynamic characterization of healthy and pathological voice quality, effects of dysphonia on voice and speech, articulatory coordination in Moebius syndrome, as well as L1 acquisition and pathological speech.

Current and future work aims to improve protocols for the evaluation of speech and to develop techniques for automatic processing in order to study changes in speech and voice across different populations. This work is carried out in coordination with the theme Methods: Corpora, analysis tools, experimental and computational approaches.

The LPP has several active projects in this area, in particular the international project ChaSpeePro whose goal is to characterize different types of motor speech disorders using a database of more than 100 patients.

Another current project studies how speech evolves over the lifespan. This research continues to use the longitudinal database PATATRA, which includes annual recordings of the same speakers for more than ten years.

The lab also studies prosody as a means of dynamic coordination in order to understand the deterioration of motor behavior due to aging and the deficits that are due to different types of dysarthria.

In addition, the large-scale project INSPECT is developing a multidimensional model of the effects of aging on speech motor control. Another project in collaboration with Orange, IRCAM and the LIA is refining the specification of voice attributes and developing ways to use them to create or modify voices.
