f0 contrast paradox in second language learners' phonation strategy - Evidence in English narrow focus syllables

摘要

This paper conducts acoustic experiments from a signal processing perspective, to examine the “-/a/ /C_ (C)” narrow focus syllable processing strategy of Chinese L2 learners of English. The research discusses f0 as a key phonatory acoustic parameter. A result of “tight” Chinese CV structure in contrast with a “loose” English CV(C) structure obtained from our previous study has been verified in the current research. The f0 contrast of L1 versus L2 groups is reflected by distinctive pitch ranges and L1 cognitive mechanism is transferred and modified in the application of speaker strategy.
