普通话的声调主要由F0曲线来表达，但它们在时长和振幅曲线上也存在一致性差异。这些因素的贡献进行了研究，通过使用信号相关的噪声刺激，其中自然语音被操纵，使其没有F0或共振峰结构，但保留其原始的幅度轮廓和持续时间。声调2，3和4是可察觉的，从刚刚的幅度轮廓，即使持续时间也不是一个线索。在另外两个实验中，通过从原始音节的每个部分提取小段来检查音节过程中音调的关键信息的位置。声调2和3经常相互混淆，并且没有太多F0变化的片段最常被听到为声调1。然而，也有一些情况下，一个低的，不变的音高被听到作为第三声，这表明即使在普通话中也有部分语域效应。F0与振幅呈正相关，即使两者都是在基音周期的基础上计算的。两者合计，结果表明，普通话声调实现的不仅仅是F0模式，即幅度轮廓可以使用B听众作为线索的音调识别，并不是每一个部分的F0模式明确地表明了原来的音调。
While the tones of Mandarin are conveyed mainly by the F0 contour, they also differ consistently in duration and in amplitude contour. The contribution of these factors was examined by using signal-correlated noise stimuli, in which natural speech is manipulated so that it has no F0 or formant structure but retains its original amplitude contour and duration. Tones 2, 3 and 4 were perceptible from just the amplitude contour, even when duration was not also a cue. In two further experiments, the location of the critical information for the tones during the course of the syllable was examined by extracting small segments from each part of the original syllable. Tones 2 and 3 were often confused with each other, and segments which did not have much F0 change were most often heard as Tone 1. There were, though, also cases in which a low, unchanging pitch was heard as Tone 3, indicating a partial effect of register even in Mandarin. F0 was positively correlated with amplitude, even when both were computed on a pitch period basis. Taken together, the results show that Mandarin tones are realized in more than just the F0 pattern, that amplitude contours can be used b listeners as cues for tone identification, and that not every portion of the F0 pattern unambiguously indicates the original tone.
