Charlotte Benoit
PhD student – Assistant Professor
After completing my residency and earned my medical degree in Paris in Otolaryngology, I was able to join the pediatric ENT team of Prs Teissier and Van Den Abbeele at the Robert Debré hospital in 2019, where I dedicate a large part of my activity to hearing loss in children, including the cochlear implants procedures. I met Dr Laurianne Cabrera and Pr Christian Lorenzi and I began to have an interest in the development of auditory perception in children, a field of research that interests me especially for the possibilities of clinical improvement for children I see in my daily clinical practice. I moved to Seattle in 2022, to work with Pr Jay Rubinstein’s team, for a research year focused on the auditory perception in subjects with hearing loss due to the STRC mutation. In November 2022, I started a PhD with Dr. Laurianne Cabrera, with a project on the developmental trajectory of auditory processing and speech perception in noise in normal hearing children and children with hearing loss between 5 and 10 years old.

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.

Language acquisition in atypical development
Knowing the mechanisms underlying typical language acquisition also makes it possible to explore whether or not these mechanisms are present in populations with atypical language acquisition and could be involved in their learning difficulties.

Lexical-semantic development
Our studies aim to understand the neural mechanisms underlying this development in monolingual and bilingual children.

Acquisition of phonological biases in lexical processing
We aim to understand how different types of sounds, as well as their arrangements within the words of a language, influence the acquisition and lexical processing of French, German, and Franco-German bilingual speakers.

Vocabulary growth and sound symbolism
Our aim is to study whether the sensitivity to sound symbolism in infancy is linked to emerging vocabulary skills.

Voice familiarity in the processing of word meanings
This project aims to investigate whether familiarity with the speaker’s voice facilitates lexical-semantic processing in infants.
