“…Further, the cross‐modal compensation observed at the behavioral level is accompanied by plastic changes in the visual and auditory networks involved during visual and audiovisual speech integration (Giraud et al ., 2001b; Lagleyre, Rouger, Laborde et al ., 2006; Lee, Giraud, Kang et al ., 2007). Lastly, our behavioral data in CI deaf patients suggest a synergy between vision and audition during the first years after implantation, leading to an increase of performance in each single modality – at least for men, whose speechreading processing abilities immediately post‐implant was poorer than that of women (Strelnikov, 2008). Similarly, such a synergetic phenomenon can also be observed at the cortical level, as expressed by a progressive increase in the activity level of the visual and auditory areas in response to stimulation by auditory words following the recovery of speech comprehension (Giraud et al , 2001b).…”

“…Our results were rather unexpected given that long periods of deafness tend to be accompanied by the acquisition of a high proficiency for word speechreading (Rouger et al ., 2007; Strelnikov et al ., 2008). Consider however that in our study, stimuli were short meaningless phonetic structures without semantic cues.…”

“…However, this conclusion was reconsidered when the gender of subjects was taken into account (Strelnikov, 2008). In NH participants, even though overall performance was low (less than 10% for word recognition), women significantly outperformed men at word speechreading (12% vs. 7%, respectively).…”

“…The approaches described above that allow manipulation of different levels of speech integration during speechreading can be implemented not only in behavioral but also in neuroimaging studies. According to a recent model of continuous speech processing (Strelnikov, 2008), the more prediction and integration are used for speech processing, the greater the expected involvement of right hemispheric structures, especially the posterior frontal and posterior temporal areas of the right hemisphere. Extensive activations in the posterior parts of the superior and middle temporal regions and in the posterior parts of the middle and inferior frontal regions were reported bilaterally for speechreading of isolated words both for congenitally deaf subjects and hearing controls (Capek, MacSweeney, Woll et al ., 2008).…”

Deguine, O. (2009). Role of speechreading in audiovisual interactions during the recovery of speech comprehension in deaf adults with cochlear implants. Scandinavian Journal of Psychology, 50, 437-444.Speechreading is an important form of communicative activity that improves social adaptation in deaf adults. Cochlear implantation allows interaction between the visual speechreading abilities developed during deafness and the auditory sensory experiences acquired through use of the cochlear implant. Crude auditory information provided by the implant is analyzed in parallel with conjectural information from speechreading, thus creating new profiles of audiovisual integration with implications for brain plasticity. Understanding the peculiarities of change in speechreading after cochlear implantation may improve our understanding of brain plasticity and provide useful information for functional rehabilitation of implanted patients. In this article, we present a generalized review of our recent studies and indicate perspectives for further research in this domain.

“…Our findings indicate that the processes recruited for words differ from those for pseudo-words and the neural response elicited is correlated with the lexical specification. Using the terms of Strelnikov, the MMN modulations can be seen as the result of two different predictions, one served by an inductive (parallel/topdown) and one by a deductive (sequential/bottom-up) processes (Strelnikov, 2008). As opposed to pseudo-words, semantic information can overrule the effect of violated stress in a single word paradigm by acting as a top-down influence, so that a meaning first process compensate for the prediction error.…”

In the present study, we investigate how lexicality affects the processing of suprasegmental features at the word level. In contrast to earlier studies which analyzed the role of either segmental or suprasegmental feature in language processing our aim was to investigate the effect of the lexical status on the processing of violated stress pattern defined by linguistic rules. We have conducted a passive oddball ERP experiment, presenting a frequent CVCV word with legal (familiar) and illegal (unfamiliar) stress patterns. Former results obtained with pseudo-words in a similar paradigm enabled to assess the influence of lexical information on stress processing. The presence of lexically relevant information resulted in different ERP patterns compared to those obtained with pseudo-words. We obtained two consecutive MMN responses to the illegally stressed words while violating the illegal stress pattern with a legal one the deviant stimulus elicited two consecutive MMN responses as well. In the latter condition lexicality clearly enhanced the comparison of prosodic information between standard and deviant stimuli, as these components very completely missing when presenting pseudo-words. We interpret the results that lexicality acts as a filter since in the absence of lexical familiarity unfamiliar stress patterns are discriminated better. Our results highlight that even when stress is fully predictable, it is taken into account during pre-attentive processing of linguistic input.

Brain Prediction of Auditory Emphasis by Facial Expressions During Audiovisual Continuous Speech

et al. 2013

The visual cues involved in auditory speech processing are not restricted to information from lip movements but also include head or chin gestures and facial expressions such as eyebrow movements. The fact that visual gestures precede the auditory signal implicates that visual information may influence the auditory activity. As visual stimuli are very close in time to the auditory information for audiovisual syllables, the cortical response to them usually overlaps with that for the auditory stimulation; the neural dynamics underlying the visual facilitation for continuous speech therefore remain unclear. In this study, we used a three-word phrase to study continuous speech processing. We presented video clips with even (without emphasis) phrases as the frequent stimuli and with one word visually emphasized by the speaker as the non-frequent stimuli. Negativity in the resulting ERPs was detected after the start of the emphasizing articulatory movements but before the auditory stimulus, a finding that was confirmed by the statistical comparisons of the audiovisual and visual stimulation. No such negativity was present in the control visual-only condition. The propagation of this negativity was observed between the visual and fronto-temporal electrodes. Thus, in continuous speech, the visual modality evokes predictive coding for the auditory speech, which is analysed by the cerebral cortex in the context of the phrase even before the arrival of the corresponding auditory signal.
