The speech of nonnative, late English language learners usually exhibits an accent that results from transferring the phonological rules and segmental or suprasegmental features from their first language (L1) into their English speech. Second language (L2) learners may also create novel pronunciations of English sounds that are not part of their L1 (e.g., Best, 1995; Flege, 1995). Native-like attainment in L2 pronunciation by adult language learners is the exception rather than the rule (Bongearts, 1999), yet most adult learners wish to speak the L2 without an accent.
