The use of lexical and sublexical cues in speech segmentation by second language learners of English
This study examined the use of lexical and sublexical cues in speech segmentation by Mandarin L2 learners of English, focusing on
two types of lexical cue, lexical knowledge and semantic relatedness, and three coda (sublexical) cues, /n, s, ŋ/ due to their
varying phonotactic probabilities in Mandarin and English. Thirty-five native English speakers and 30 L2 learners participated in
two experiments. Experiment 1 showed that learners were able to use lexicality as a cue to segment L2 speech. The lexicality
effect significantly interacted with L2 proficiency. Experiment 2 showed that learners did not use semantic cues to the same
extent as native listeners did. All participants experienced more difficulty with word boundary identification preceded by /s/.
This difficulty may stem from weak allophonic cues of /s/ in English. L2 learners with better proficiency may be better at
recognizing familiar words from continuous speech, thus more efficiently utilizing the lexicality cue.
