The relation between perception and action remains a fundamental question for neuroscience. In the context of speech processing, existing data suggest an interaction between auditory and speech-motor cortices (1), but the underlying mechanisms remain incompletely characterized. Moreover, data suggest that rhythmicity and synchrony play a crucial role for the speech production and perception loop. The speech audio signal carries a clear temporal pattern, with the syllable rate being extremely stable across languages (2). This rhythmicity seems to be crucial for speech comprehension, and some evidence suggests that it entrains auditory cortex activity yielding the correct syllable parsing required for the subsequent decoding of the signal (3, 4). I use a combination of neurophysiological and psychophysical tools to understand how the produced speech-rhythms emerge (5) and how they interact with the perceived ones.
