What mechanisms help infants and children process speech when it is degraded? Are these mechanisms the same for infants and children with typical hearing and those with hearing loss? How do hearing devices affect these speech processing mechanisms? The aim of my research is to investigate these questions using both behavioural and neural perspectives.
Ongoing project
A neuroscientific study of the structure of the bilingual lexicon: the impact of linguistic distance, word type and word relationships on the developing brain
Our aim is to study the lexico-semantic organisation in bilingual infants, in order to explore the internal structure of the bilingual lexicon.

Statistical learning in 10-month-old infants using acoustically degraded speech – TP-VOC
We’re trying to understand the role of acoustic information in speech in statistical learning and the detection of patterns in language.

Infant entrainment to artificial voices
In this project, we are testing how infants react to hearing voices that either sound more artificial (machine-like), more human (human-like), or even more familiar (voice clone of the infant’s mother). Funded by SSHRC Canada (2025-2027)

Global speech
This project aims to unveil the general auditory mechanisms involved in the early development of speech perception by using both behavioural and neurophysiological tools with infants.

Neural study of bilingual lexicon structure: impact of language distance, word type, and relatedness in the developing brain
Our aim is to investigate lexical-semantic organisation in bilingual infants, as a lens into the internal structure of bilingual lexicon. More specifically, we aim to investigate how lexical-semantic organisation – both thematic and taxonomic – in the bilingual brain is shaped by language distance and cognate status of words.

Early speech perception and processing of phonological information in lexical acquisition in French- and Akan-learning infants and toddlers
This cross-linguistic project explores how French and Akan-learning toddlers process phonological information (consonants, vowels, tones) when learning words in their native and non-native languages.

Linking early phonolexical acquisition and later vocabulary development
In this project, we test the proposal that a crucial milestone in language acquisition is reached when infants discover which sounds (consonants versus vowels) are more important at the lexical level in their native language, leading to an acceleration of subsequent vocabulary development.
