假设在自然语音的正弦波复制中，由于F0信息的丢失，词汇声调识别将受到严重损害，但即使在有限的声调信息的情况下，句子层面的语言信息也可以被提取。41名以普通话为母语的听众参与了实验。结果表明，正弦波声调识别的正确率平均只有32.7%。然而，正弦波句子识别的表现非常准确，平均正确率约为92%。因此，词汇声调对句子识别的功能负荷是有限的，正弦波句子的高水平识别很可能归因于受自上而下过程影响的知觉组织。(C)2012年美国声学学会
It is hypothesized that in sine-wave replicas of natural speech, lexical tone recognition would be severely impaired due to the loss of F0 information, but the linguistic information at the sentence level could be retrieved even with limited tone information. Forty-one native Mandarin-Chinese-speaking listeners participated in the experiments. Results showed that sine-wave tone-recognition performance was on average only 32.7% correct. However, sine-wave sentence-recognition performance was very accurate, approximately 92% correct on average. Therefore the functional load of lexical tones on sentence recognition is limited, and the high-level recognition of sine-wave sentences is likely attributed to the perceptual organization that is influenced by top-down processes.
