    内容摘要:

    Any sound can be decomposed into temporal envelope (E) and temporal fine structure (TFS). E has been shown to play a critical role for speech perception in quiet. The contribution of the temporal fine structure (TFS) cues for speech perception in noise is still under debate. We have shown previously that TFS plays a dominant role in lexical tone recognition in quiet and that both E and TFS contribute to tone recognition in noise. Two new experiments were carried out to examine the relative contributions of E and TFS to sentence recognition in noise for both English and Mandarin Chinese.  Results showed that sentence recognition in noise had a strong reliance on E. The TFS showed a small effect on sentence recognition in noise. These observations were true for both types of maskers, i.e., speech-spectrum-shaped noise and two-talker babbles and were consistent in both languages, i.e., English and Mandarin Chinese.
