“…That possible explanation implies that infants at that developmental stage may have an AV representation of syllables so they detect a novel, unpredicted sound that is incongruent with the mouth movement. However, a study conducted by the same research team on an older group of monolinguals (7‐ to 10‐month‐olds) showed the reverse effect: more looking to the eyes in the incongruent condition (Mercure et al., 2022). Interpretation of the latter result was that infants shifted their attention away from mismatching mouth movements to tolerate articulatory inconsistencies.…”

Humans pay special attention to faces and speech from birth, but the interplay of developmental processes leading to specialization is poorly understood. We investigated the effects of face orientation on audiovisual (AV) speech perception in two age groups of infants (younger: 5‐ to 6.5‐month‐olds; older: 9‐ to 10.5‐month‐olds) and adults. We recorded event‐related potentials (ERP) in response to videos of upright and inverted faces producing /ba/ articulation dubbed with auditory syllables that were either matching /ba/ or mismatching /ga/ the mouth movement. We observed an increase in the amplitude of audiovisual mismatch response (AVMMR) to incongruent visual /ba/‐auditory /ga/ syllable in comparison to other stimuli in younger infants, while the older group of infants did not show a similar response. AV mismatch response to inverted visual /ba/‐auditory /ga/ stimulus relative to congruent stimuli was also detected in the right frontal areas in the younger group and the left and right frontal areas in adults. We show that face configuration affects the neural response to AV mismatch differently across all age groups. The novel finding of the AVMMR in response to inverted incongruent AV speech may potentially imply the featural face processing in younger infants and adults when processing inverted faces articulating incongruent speech. The lack of visible differential responses to upright and inverted incongruent stimuli obtained in the older group of infants suggests a likely functional cortical reorganization in the processing of AV speech.

This study aimed to investigate the development of audiovisual speech perception in monolingual Uzbek and bilingual Uzbek-Russian-speaking children, focusing on the impact of language experience on audiovisual speech perception and the role of visual phonetic (i.e. mouth movements corresponding to phonetic/lexical information) and temporal (i.e. timing of speech signals) cues.Three hundred twenty-one children in Tashkent, Uzbekistan, between the ages of 4 and 10 years discriminated /ba/ and /da/ syllables across three conditions: auditory-only, audiovisual phonetic (i.e., the sound accompanied by mouth movements), and audiovisual temporal (i.e, sound onset/offset accompanied by mouth opening/closing). Effects of modality (audiovisual phonetic, audiovisual temporal, or audio-only cues), age, group (monolingual vs. bilingual), and their interactions were tested using a Bayesian regression model.Participants performed better in the audiovisual phonetic modality compared to the auditory modality. However, no significant difference between monolingual and bilingual children was observed across all modalities. This finding stands in contrast with earlier studies. We attribute the contrasting findings of our study and the existing literature to the cross-linguistic similarity of the language pairs involved. When the languages spoken by bilinguals exhibit substantial linguistic similarity, there may be an increased necessity to disambiguate speech signals, leading to a greater reliance on audiovisual cues. The limited phonological similarity between Uzbek and Russian might have minimized bilinguals’ need to rely on visual speech cues, contributing to the lack of group differences in our study.
