Voyelles brèves en parole conversationnelle

- Résumé : This work deals with the phenomenon of speech reduction in conversational speech. An automatic and a manual analysis have been conducted. The automatic analysis show a strong reduction in the vocalic system and very short durations for a great proportion of vowels in the corpus. The manual analysis highlights the specific realisations of extra-short vowels (30ms) according to voicing, formants, indentification and lexicon.

Quelques cas particuliers de détachement à gauche - ou la prosodie à l'aide de la syntaxe -

- Résumé : This paper presents a pilot study, which aims at characterizing four types of left-detachment in French. Whereas one of the four constructions is clearly composed of two clauses (a clause being defined as a minimal macro-syntactic unit), it is uncertain whether the other three contain one or two clauses. A bundle of prosodic features are implemented into a statistic model in order to predict the one or two-clause status of these ambiguous constructions. This quantitative procedure is also a first step to highlight specific prosodic marking of one vs. two-clause constructions.

La voyelle nasale en PB et son appendice nasal : étude acoustique et aérodynamique

- Résumé : This work investigates the acoustic variability of nasal vowel realization in Brazilian Portuguese caused by right-hand segmental context. Specifically, it appears that a discernible nasal murmur is measurable only when the nasal vowel precedes a plosive, but not before fricatives. According to an alternative hypothesis, there would be no difference between the nasal gestures in the two contexts. By means of both acoustic and aerodynamic data (nasal and oral airflow), a nasal appendix has been identified in both /p/ and /f/ contexts, which corresponds to the closing gesture of the lips and shows a high nasal airflow rate. Our alternative hypothesis is hence supported, while the acoustic difference is explained in terms of gestural overlap.
