Abstract: This talk presents the findings of four experimental studies of intonation (production and perception) across three African tone languages with varying degrees of tonal complexity: three, four, and five level tone systems. While the results uphold some of the previous findings in the study of intonation in African languages, they reveal systematic tendances that current models of tonal and intonational representation cannot account for. This talk will briefly introduce a new unified representational model for tone and intonation that accounts for the observed data and makes testable predictions about the place of intonation in tone languages. The new model is then used as parameters in a generative cross-linguistic intonation algorithm. The algorithm is a proof of concept that a unified representation for tone and intonation can truly take full advantage of the advances in tonal and intonational research.

Bio: Dr. Mamadou's research focuses on the representation and computation of tone and intonation, which are two of the most widely shared aspects of human languages. From a theoretical standpoint, he is interested in questions of representation in phonology and how they play into the computation of different phonological processes. Empirically, his work focuses on the prosodic systems of understudied languages in Sub-Saharan Africa, where he conducts fieldwork in a variety of languages, including Ede Chaabe, Baatonum, Dan, and Zarma, spoken across Benin, Côte-d'Ivoire and Niger.

Prosodic cues as biomarkers for pathologies detection

Résumé :
In recent works we proposed that the prosodic parameters of speech bring information about biological and sociolinguistic aspects. In addition, it may lead us to a better description of the vocal alterations resulting from pathologies, like Parkinson Disease (PD), schizophrenia, COVID-19, and the syndrome named Long COVID-19. Furthermore, these changes may be confused with natural vocal variations in elderly people's speech, namely presbyphonia. In early studies about Brazilian Portuguese, we noticed that patients with schizophrenia showed less f0 variation and greater difficulty to implement prosodic constituents larger than a prosodic word, using unappropriated pauses and irregular f0 inflections. Covid-19 patients showed related results, concerning mainly the pauses. In the elderly people with PD, a first exploratory study showed that the variables spectral emphasis and HNR, which respectively indicated more vocal effort and more breathiness in the Parkinson group, although they are aspects expected in people with PD, they should be considered in future observations about these characteristics in the speeches of elderly with presbyphonia and the group that had COVID-19. The research to be conducted in the next six months aims to understand if these alterations are language specific, comparing Portuguese with French, and explore the differences the alterations among Parkinson Disease, Presbyphonia and Long Covid-19.
