title: Language exposure facilitates talker learning prior to language comprehension, even in adults.
abstract: Adults show a native language advantage for talker identification, which has been interpreted as evidence that phonological knowledge mediates talker learning. However, infants also show a native language benefit for talker discrimination, suggesting that sensitivity to linguistic structure due to systematic language exposure promotes talker learning, even in the absence of functional phonological knowledge or language comprehension. We tested this hypothesis by comparing two groups of English-monolingual adults on their ability to learn English and French voices. One group resided in Montréal with regular exposure to spoken French; the other resided in Storrs, Connecticut and did not have French exposure. Montréal residents showed faster learning and better retention for the French voices compared to their Storrs-residing peers. These findings demonstrate that systematic exposure to a foreign language bolsters talker learning in that language, expanding the gradient effect of language experience on talker learning to perceptual learning that precedes sentence comprehension.
