To adapt to unforeseen circumstances during speech production, the motor system integrates sensory information (e.g., auditory feedback) and benefits from rhythmic grouping, which is characterized by prosody. However, a speaker's sensorimotor system processes acoustic events related to their own voice differently from those of others. This thesis aims to examine the flexibility of speech production by analyzing the organizing role of both prosody and a speaker's subjective sensation of control over his voice (i.e., the sense of agency related to his voice).Experiments of auditory feedback perturbations were conducted with French-speaking female speakers. With delayed auditory feedback (DAF), the duration difference between accented and unaccented vowels increased, highlighting greater flexibility during accent production. Furthermore, DAF induced a reorganization of speech rhythm with enhanced syllabic grouping. With a constant shift in the fundamental frequency (f0) of auditory feedback, the majority of female speakers aligned their f0 with the modified auditory feedback, suggesting that their sensorimotor system processed the perceived voice as an external input. The simultaneous presence of DAF and an f0 shift resulted in a reduction of DAF effects compared to the condition without an f0 shift. This observation suggests a reduction in the sense of agency related to the voice among female speakers, as well as an interaction between rhythmic organization and sense of agency in sensorimotor processes of speech production

This study on segmental reduction (i.e. deletion or temporal reduction) in spontaneous French allows us to propose two research methods for linguistic studies on large corpora, to investigate different factors of variation and to bring new insights on the propensity of segmental reduction. We applied the descendant method using forced alignment with variants when it concerns a specific reduction phenomena. Otherwise, we used the ascendant method using absent and short segments as indicators. Three reduction phenomena are studied: schwa elision, /ʁ/ deletion and the propensity of segmental reduction. The descendant method was used for analyzing schwa elision and /ʁ/ deletion. Common factors used for the two studies are post-lexical context, speech style, sex and profession. Schwas elision at initial syllable position in polysyllabic words and post-consonantal /ʁ/ deletion at word final position are not always conditioned by the same variation factors. Similarly, lexical schwa and epenthetic schwa are not under the influence of the same variation factors. The study on the propensity of segmental reduction allows us to apply the ascendant method and to investigate segmental reduction in general. Results suggest that liquids and glides resist less the reduction procedure than other consonants and nasal vowels resist better reduction procedure than oral vowels. Among oral vowels, high rounded vowels tend to be reduced more often than other oral vowels
