Why do some people learn new speech sounds more easily than others?
I combine speech science, cognitive psychology, artificial intelligence and data science to find out, and to understand how listeners respond to synthetic voices.
Research themes
AI voices
Voice cloning, text-to-speech, naturalness and speaker similarity.
Second-language speech
Perception, production and phonetic training in a new language.
Individual differences
How auditory processing, memory and experience predict learning success.
EEG & FFR
Neural encoding of speech and its link to perception and learning.
Acoustic phonetics
Formant dynamics, voice onset time, prosody and speech timing.
Data science
Mixed-effects models, machine learning and reproducible workflows.
Current projects
SoundCoach
Exploring how AI-supported pronunciation training can adapt to each learner, moving beyond one-size-fits-all feedback.
ProsodAI
How native and second-language listeners perceive AI-generated speech, and which acoustic cues make it sound human.
EEG & frequency-following responses
Linking the brain's encoding of speech sounds with perception, production and learning in a second language.

Try the tasks
Browser-based tasks I use to measure abilities that contribute to speech and language learning.
Serial Reaction Time Task
A measure of procedural and implicit learning: respond to boxes on screen as quickly as you can while a hidden sequence repeats.

A measure of phonological awareness: listen to a word and remove one sound from its beginning, middle or end.
Teaching & supervision
I teach phonetics, phonology, applied linguistics and research methods, and supervise dissertation projects in experimental design, acoustic phonetics, second-language acquisition and speech technology.
Programming
Machine learning
Speech processing
Web application design
