动态音高又称语调，在言语交际中既传达语义又传达语用意义。虽然这种线索的改变是有害的语音清晰度在噪声中，所涉及的机制知之甚少。本研究采用任务诱发瞳孔反应的心理生理学方法，考察了噪声环境中动态音高线索改变对言语知觉的影响。实验结果表明，在噪声条件下的句子识别中，瞳孔的扩大程度随着动态音高强度的增加而增加。两者结合识别准确率数据，结果表明，在语音感知与动态音高变化的知觉唤醒的参与。
Dynamic pitch, also known as intonation, conveys both semantic and pragmatic meaning in speech communication. While alteration of this cue is detrimental to speech intelligibility in noise, the mechanism involved is poorly understood. Using the psychophysiological measure of task-evoked pupillary response, this study examined the perceptual effect of altered dynamic pitch cues on speech perception in noise. The data showed that pupil dilation increased with dynamic pitch strength in a sentence recognition in noise task. Taken together with recognition accuracy data, the results suggest the involvement of perceptual arousal in speech perception with dynamic pitch alteration.
