To what extent do French listeners perceive differences in accent location within words? An EEG investigation

Résumé

In this study, we provided a more in-depth examination of the ability of French listeners to perceive and use the location of accent in a discrimination task. Event-related potentials (ERPs) were recorded while participants performed a same-different task. Different stimuli diverged either in one phoneme (e.g., /'ʒyʁi/-/'ʒyʁɔ̃/) or in accent location (e.g., /'ʒyʁi/-/ʒy'ʁi/). Although, participants reached 90% of correct responses, ERPs results indicated that a change in accent location was not detected while a change in one phoneme was detected in two time- windows, the first between 400 and 500 ms, and the second between 500 and 650 ms after target onset. It results that in the early moments of speech processing, stimuli that are phonemically identical but that differ in accent location are perceived as being strictly similar. The good performance observed in behavioral responses was interpreted in relation to attentional processes
