This study examines the significance of language use for second language (L2) accent and tests it against factors such as length of residence (LOR) and age of onset (AO). Participants include 42 non-native speakers of English and 8 native speaker controls. Read-aloud items and guided free-speaking tasks are rated on a 5-point scale. Correlation analyses confirm the significance of AO, LOR, and experiential factors such as first language (L1) use, breadth of L2 use across multiple modes, and especially domain-based L2 use, such as personal, interactive contact with native speakers of the target language. Results suggest that experiential quality has a more significant impact on accent than experiential quantity and that, according to multiple regression models, experience is independent of the influences of AO and LOR. Based on these analyses, closer investigations of language experience and its connections to LOR are recommended. (Contains 1 figure, 7 tables, and 3 notes.)
