Prosody As Dynamic COordinative DEvice – PASDCODE

Submission summary

We test two hypotheses on the role of prosody in speech motor control. 1) the prosodic structure shapes the coordination between the rhythmic regularities present in the speech signal at different time scales. This has the effect of constraining the interactions between the many individual phonetic processes contributing to these regularities. 2) the control of the speech stream is not uniformly distributed over the duration of speech utterances. Indeed prominent syllables are better controlled than other syllables. These hypotheses will be systematically tested and their implications will be investigated through the analyses of available speech corpora and through the recordings of speakers from different languages. These hypotheses have direct implications for our understanding of the degradation of speech motor behaviour due to aging and to its impairment due to different types of dysarthria which will be investigated through the analysis of available corpora.
