语音对比是由多个声学维度发出的信号，但这些维度并不具有同等的诊断性。此外，语音中声学维度的相对诊断性或权重在语音感知和语音产生的不同交际环境中会发生变化。然而，关于说话者是否，如果是，如何在不断变化的交际需求背景下调整言语以强调不同的声学维度，文献仍然不清楚。在这里，我们研究了灵活的线索权重在语音产生和感知中的相互作用，包括振幅和持续时间，普通话语音语音的次要非频谱声学维度，自然语音和耳语，这消除了基本频率轮廓，主要声学维度。与发音的普通话相比，母语者的发音和低语普通话的持续时间和幅度都有所增强。当非语音振幅调制噪声模拟这些增强模式时，将噪声识别为普通话词汇音调类别比识别为语音振幅和持续时间线索的噪声更准确。因此，说话者夸大了耳语中的次要线索，听者利用了这些信息。然而，普通话四种声调之间的增强并不对称，这表明这种增强的实现可能存在限制。
Speech contrasts are signaled by multiple acoustic dimensions, but these dimensions are not equally diagnostic. Moreover, the relative diagnosticity, or weight, of acoustic dimensions in speech can shift in different communicative contexts for both speech perception and speech production. However, the literature remains unclear on whether, and if so how, talkers adjust speech to emphasize different acoustic dimensions in the context of changing communicative demands. Here, we examine the interplay of flexible cue weights in speech production and perception across amplitude and duration, secondary non-spectral acoustic dimensions for phonated Mandarin Chinese lexical tone, across natural speech and whispering, which eliminates fundamental frequency contour, the primary acoustic dimension. Phonated and whispered Mandarin productions from native talkers revealed enhancement of both duration and amplitude cues in whispered, compared to phonated speech. When nonspeech amplitude-modulated noises modeled these patterns of enhancement, identification of the noises as Mandarin lexical tone categories was more accurate than identification of noises modeling phonated speech amplitude and duration cues. Thus, speakers exaggerate secondary cues in whispered speech and listeners make use of this information. Yet, enhancement is not symmetric among the four Mandarin lexical tones, indicating possible constraints on the realization of this enhancement.
