Brain–speech entrainment in typical and dyslexic readers
Mathieu Bourguignon, San Sebastian
During continuous speech listening, oscillations within auditory cortices entrain to speech rhythmicity at syllable (4–7 Hz) and phrasal (below 1 Hz) pace. This phenomenon widely known as brain–speech entrainment can be revealed by means coherence analysis between electrophysiological recordings and the temporal envelope of heard speech. In this talk, I will first review the current knowledge of brain–speech entrainment in typically developing subjects. I will then present how it is altered in dyslexic readers and elaborate on what that tells us about the neuronal underpinning of dyslexia. Finally, I will touch upon few lines of research around brain–speech entrainment I’m currently exploring.
