Prosodic grouping biases from birth to adulthood in monolingual speakers

This project studies how adults and young children use variations in intensity, duration and intonation to group syllables into word units.

Characterisation of the processing of acoustic cues and speech processing in noise in normal-hearing and hearing-impaired children with mild to moderate sensorineural hearing loss – SPINTAE

In this large-scale study, we aim to evaluate the processing abilities of different acoustic indices between 5 and 10 years of age in children without hearing problems and those with sensorineural hearing loss.

Neural processing of temporal modulations and computational modelling – Heardevcomp

The processing of acoustic information, such as variations in sound amplitude over time called “sound envelope”, is of crucial importance for speech perception in adults. We will seek to characterize the evolution of sound envelope processing during development in infants.

Perception of sibilant consonants and understanding of plurals in hearing-impaired children – LaulauH

The objective is to understand to what extent a deficit in perception of certain sounds, such as “s” and “z”, when they are heard in background noise, can have an impact on oral comprehension of the plural in subject-verb agreement.

Development of the auditory system and speech perception in infants- BabySIN

On the one hand, the cerebral processing of different acoustic variations of sounds is studied in 3-month-old infants using the electroencephalography technique. On the other hand, the ability to perceive speech in noise in these infants is measured using an observation technique.

Proccesing phonological information while learning and recognizing words

It has been proposed that consonants carry more weight than vowels in lexical processing. Given the timing of acquisition observed in French, we have proposed that this consonant bias emerges in connection with phonological and (proto)lexical acquisition, a hypothesis we are currently testing.

Predicting language outcomes in typical development

We explore how elementary perception and learning mechanisms are linked to language acquisition. To this end, we test infants on different perception and learning mechanisms, at different stages of their development and up to 2-3 years of age.
