Most second language acquisition research focuses on linguistic structures, and less research has examined the acquisition of sociolinguistic patterns. The current study explored the perceptual classification of regional dialects of American English by native and non-native listeners using a free classification task. Results revealed similar classification strategies for the native and non-native listeners. However, the native listeners were more accurate overall than the non-native listeners. In addition, the non-native listeners were less able to make use of constellations of cues to accurately classify the talkers by dialect. However, the non-native listeners were able to attend to cues that were either phonologically or sociolinguistically relevant in their native language. These results suggest that non-native listeners can use information in the speech signal to classify talkers by regional dialect, but that their lack of signal-independent cultural knowledge about variation in the second language leads to less accurate classification performance.

IntroductionLearning the sound system of a second language involves the acquisition of a new phonological system, including new phoneme categories, new phonological rules or constraints, and new prosodic structures, as well as the acquisition of a new social indexical system, including phonological and phonetic markers for age, gender, and socioeconomic status. The acquisition of sociolinguistic knowledge in a second language is important not only for developing appropriate social communication skills in a second culture, but also has implications for speech processing. Native listeners exhibit processing benefits for familiar and standard varieties of their first language in a range of tasks, including sentence and word recognition (Clopper & Bradlow, 2008;Labov & Ash, 1997) and lexical decision (Floccia, Goslin, Girard, & Konopczynski, 2006). Knowledge about dialect variation 1 , therefore, may also have implications for online speech processing for non-native listeners.Corresponding author: Cynthia G.
