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

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.
