Recent research in Human-Computer Interaction (HCI) has focused on equipping machines with means of communication that are used between humans, such as speech and accompanying gestures. For the hearing impaired , the visual components of speech, such as lip movements, or ges-tural languages such as sign language are available means of communication. This has led researchers to focus on lip read...

A large body of literature has shown that phonemic voicing contrasts are preserved in the production and perception of whispered speech. Nevertheless, it is unclear to what extent allophonic voicing is also maintained in whisper. The present study investigates whether a non-contrastive voicing distinction in Spanish fricatives – which results from voice assimilation in obstruent clusters – is a...

Perception of spoken language requires attention to acoustic as well as visible phonetic information. This article reviews the known differences in audiovisual speech perception in children with autism spectrum disorders (ASD) and specifies the need for interventions that address this construct. Elements of an audiovisual training program are described. This researcher-developed program deliver...

Stuttering is a neurodevelopmental disorder characterized by frequent and involuntary disruptions during speech production. Adults who stutter are often subject to negative perceptions. The present study examined whether negative social and cognitive impressions are formed when listening to speech, even without any knowledge about the speaker. Two experiments were conducted in which naïve parti...

In a previous study [1] on vowel rounding anticipatory perception through a fricative consonant stream with a gating paradigm, we discovered that auditory information could be, in this VCV frame, ahead of visual information, and even of audiovisual information (hence A>AV>V). We propose here to extend this experiment to different modality-impaired groups of adults and children, namely: (i) to b...

________________________________________________________________________________________________________ French Cued Speech perception and expertise effect in hearing people Since French Cued Speech (CS) is multi-signal (lip movements and CS gestures), we conducted an eye tracking study to examine whether this perception involves integrative treatment and how expertise affects it in normally-he...

Cued Speech (CS) is an augmented lip reading system complemented by hand coding, and it very helpful to the deaf people. Automatic CS recognition can help communications between people others. Due asynchronous nature of lips movements, fusion them in automatic a challenging problem. In this work, we propose novel re-synchronization procedure for multi-modal fusion, which aligns features with fe...

This paper deals with the problem of the automated classification of cued speech gestures. Cued speech is a specific gesture language (different from the sign language) used for communication between deaf people and other people. It uses only 8 different hand configurations. The aim of this work is to apply a simple classifier on 3 images data sets, in order to answer two main questions: is 3D ...

Some theories concerning speech mechanisms assume that overlapping representations are involved in programming certain articulatory gestures and hand actions. In previous studies we have shown a compatibility effect between pronouncing or hearing meaningless syllables like [kɑ] and [ti] and simultaneously performing a power or a precision grip, respectively. The present study investigated wheth...
