Sensorimotor influences on speech perception in pre-babbling infants: Replication and extension of Bruderer et al. (2015)

Findings reveal specificity in the relation between sensorimotor and perceptual processes in pre-babbling infants, and show generalizability to a second phonetic contrast.

Infants' discrimination of consonant contrasts in the presence and absence of talker variability.

This study asked whether variability would impair or facilitate discrimination for older infants, comparing 7.5-month-old infants' discrimination of an early acquired native contrast with an acoustically subtle, non-native contrast.

Distributional Phonetic Learning at 10 Months of Age.

It is revealed that at 10 months of age, distributional phonetic learning remains effective, but is more difficult than before perceptual reorganization.

The development of visual speech perception in Mandarin Chinese-speaking children

Visual speech perception in Chinese is a developmental process that is acquired over time and is still fine-tuned well into late adolescence, and factors other than cross-linguistic differences in phonological complexity and degrees of reliance on visual information are involved in development of visual speech perception.

The development of audiovisual speech perception

The seemingly effortless and incidental way in which infants acquire and perfect the ability to use spoken language/s is quite remarkable considering the complexity of human linguistic systems.

Electrophysiological evidence of illusory audiovisual speech percept in human infants

Measuring event-related brain potentials in 5-month-old infants shows differential brain responses when conflicting auditory and visual speech cues can be integrated and when they cannot be fused into a single percept, revealing a surprisingly early ability to perceive speech cross-modally.


During the first year of life, infants go from perceiving speech sounds primarily based on their acoustic characteristics, to perceiving speech sounds as belonging to speech sound categories relevant

Discriminating Non-native Vowels on the Basis of Multimodal, Auditory or Visual Information: Effects on Infants’ Looking Patterns and Discrimination

It is proposed that by 8 months, infants’ native vowel categories are established insofar that learning a novel contrast is supported by attention to additional information, such as visual articulations.



Two-month-old infants match phonetic information in lips and voice

Infants aged 4.5 months are able to match phonetic information in the face and voice (Kuhl & Meltzoff, 1982; Patterson & Werker, 1999); however, the ontogeny of this remarkable ability is not

Statistical phonetic learning in infants: facilitation and feature generalization.

It is demonstrated that exposure to a bimodal statistical distribution in 8-month-old infants' phonetic input can lead to increased discrimination of difficult contrasts, suggesting that infants extract acoustic/phonetic information that is invariant across an abstract featural representation.

Infant sensitivity to distributional information can affect phonetic discrimination

Auditory-visual speech integration by prelinguistic infants: perception of an emergent consonant in the McGurk effect.

Visual-fixation durations in test trials showed that the experimental group treated the emergent percept in the McGurk effect, [da] or [(delta)a], as familiar (even though they had not heard these sounds previously) and [ba] as novel.

Children's perception of visual and auditory speech.

Tests of quantitative models indicated that both preschool children and adults had available continuous and independent sources of information and the only developmental difference was less of an influence of the visual source of information for children relative to adults.

Is the integration of heard and seen speech mandatory for infants?

The research demonstrates that integration is neither as strong or consistent in infants as it is in adults, and suggests that Integration is not mandatory for young infants.

The McGurk effect in infants.

5-month-old English-exposed infants were tested for the McGurk effect and results suggest that the infants were visually influenced in the same way as English-speaking adults are visually influenced.

Speech Perception in Infants

Recovery from habituation was greater for a given acoustic difference when the two stimuli were from different adult phonemic categories than when they were from the same category.
