This study aims at characterizing the acoustic and articulatory modifications that occur in speech in noisy environments, and at examining them as compensatory strategies. Audio, EGG and video signals were recorded for a female native speaker of French. The corpus consisted of short sentences with a subject-verb-object (SVO) structure. The sentences were(More)
Speech output technology is finding widespread application, including in scenarios where intelligibility might be compromised – at least for some listeners – by adverse conditions. Unlike most current algorithms, talkers continually adapt their speech patterns as a response to the immediate context of spoken communication, where the type of interlocutor and(More)
In this study we explore how acoustic and lip articulatory characteristics of bilabial consonants and three extreme French vowels vary in Lombard speech. In the light of several theories of segments perception we have shown that formant modifications should decrease the audio intelligibility of vowels in noise. On the contrary, modification in lip(More)

23 Previous studies have demonstrated that bacteria influence microalgal metabolism, suggesting that the 24 selection and characterization of growth-promoting bacteria should offer a new strategy for improving 25 industrial algal cultivation. In the present study, 48 cultivable bacteria were isolated from marine 26 microalgae species and identified using(More)
Speech produced in noise (or Lombard speech) is characterized by increased vocal effort, but also by amplified lip gestures. The current study examines whether this enhancement of visible speech cues may be sought by the speaker, even unconsciously, in order to improve his visual intelligibility. One subject played an interactive game in a quiet situation(More)
How and why do vocal tract resonances and articulation change when shouting? Vocal tract resonances R1 and R2, Open quotient, Fundamental frequency, voice intensity, larynx height, lip aperture and spreading were simultaneously recorded for a female native speaker of French, on 7 French vowels and for 3 different conditions of increasing vocal effort: "(More)
