Prosem Lecture: The Role of Auditory Feedback in Error-detection and Correction in First and Second Language Production

Topic: The Role of Auditory Feedback in Error-detection and Correction in First and Second Language Production
Speakers self-correct small variations they hear in their own speech, whether self-produced or experimentally-induced perturbations to auditory feedback. In a first language (L1), phonetic categories and therefore auditory expectations are well-established, but in a second language (L2), lack of experience with new categories may interfere with the ability to detect and correct such deviations.
We will present two companion studies testing how English speakers learning French detect such variations in their auditory feedback in both L1 and L2. In one study, speakers uttered monosyllabic English and French words while simultaneously receiving different levels of masking noise to determine how access to auditory feedback information impacts speakers’ ability to make online adjustments to self-produced speech. In a second study, speakers received altered auditory feedback, creating the perception of an error. We compare correction of these internally- and externally-generated errors to understand speakers’ sensitivity to auditory feedback in native and learned languages.
