本研究通过考察受试者使用F0音域作为说话人身份识别的线索，考察了普通话二声（中升调）和三声（低降升调）感知中的说话人标准化。选择两个扬声器，使得低音扬声器的单独2和高音扬声器的音调3出现在相同的F0高度。产生和感知实验确定了转折点（或音调的拐点）和Delta F0（起始点和转折点之间的F0差异）区分两种音调。三个音调连续变化的转折点，三角洲F0，或两个声学尺寸，然后附加到一个自然的前体短语从两个扬声器。结果表明，识别偏移，使得相同的刺激被识别为低音调的高前体条件，但作为高音调的低前体条件，在转折点变化的刺激没有显示出显着的偏移，这表明，听者正常化时，只有在相同的维度上的前体变化的刺激，偏移的幅度是更大的变化仅在Δ F0的刺激，与在转折点和Δ F0两者上变化的刺激相比，表明对于更紧密地匹配自然语音的刺激，归一化效应降低。(C)1997年美国声学学会。
This study investigated speaker normalization in perception of Mandarin tone 2 (midrising) and tone 3 (low-falling-rising) by examining listeners' use of F0 range as a cue to speaker identity. Two speakers were selected such that lone 2 of the low-pitched speaker and tone 3 of rite high-pitched speaker occurred at equivalent F0 heights. Production and perception experiments determined that turning paint (or inflection point of the tone), and Delta F0 (the difference in F0 between onset and turning point) distinguished the two tones. Three tone continua varying in either turning point, Delta F0, or both acoustic dimensions, were then appended to a natural precursor phrase from each of the two speakers. Results showed identification shifts such that identical stimuli were identified as low tones for the high precursor condition, but as high tones for the low precursor condition, Stimuli varying in turning point showed no significant shift, suggesting that listeners normalize only when the precursor varies in the same dimension as the stimuli, The magnitude of the shift was greater for stimuli varying only in Delta F0, as compared to stimuli varying in both turning point and Delta F0, indicating that normalization effects are reduced for stimuli more closely matching natural speech.
