关于语音产生的关键问题之一是听觉反馈在该过程中所扮演的角色。在这里，研究了扬声器是否对其反馈响度的短暂扰动表现出快速补偿变化。每个受试者的语音都被放大并输入 Eventide Ultraharmonizer，该谐波器会对受试者的音频反馈音量引入短暂（400 毫秒）610 dB 的扰动。在所有受试者中都发现了对两种振幅扰动类型的补偿反应，其发生时间与之前在对音调扰动的反应中观察到的潜伏期相似（-10 dB：171 ms；+10 dB：287 ms）。 (C) 2005 年美国声学学会。
One of the key questions about speech production is the role that auditory feedback plays in the process. Here, it was investigated whether speakers show fast compensatory changes to brief perturbations of the loudness of their feedback. Speech from each subject was amplified and fed into an Eventide Ultraharmonizer that introduced brief (400 ms) 610-dB perturbations to volume of the subject's audio feedback. Compensatory responses to both amplitude perturbation types were found in all subjects, which occurred at a similar latency (-10 dB: 171 ms; +10 dB: 287 ms) to that previously observed in responses to pitch perturbations.
