先前的研究表明，在连续发声过程中，语音基频（语音 F-0）会受到频移听觉反馈的影响。在本研究中，针对无意义词 [tatatas] 的前两个音节确定了频移听觉反馈对语音 F-0 轮廓的影响。结果表明，语音 F-0 是通过听觉控制的，具有较长的延迟，并且响应不会因发声本身的开始和偏移而中断。此外，在试验中发现语音F-0在频移终止后有后遗症，这表明响应持续了几秒钟。有人认为，听觉发声系统的目的不是在单音节内精确控制语音 F-0，而是在韵律背景下的超音段水平上进行控制。 (C) 2002 年美国声学学会。
Previous studies have shown that, during continuous vocalization, voice fundamental frequency (voice F-0) is modified by frequency-shifted auditory feedback. In this study, the effects of frequency-shifted auditory feedback on voice F-0 contours were determined for the first two syllables of the nonsense word [tatatas]. Results show that voice F-0 is auditorily controlled with a long latency and responses are not interrupted by the onset and offset of phonation itself. Furthermore, after-effects were found in voice F-0 in trials after the termination of the frequency shift, which indicates that the response persists for several seconds. It is argued that the purpose of the auditory-vocal system is not to control voice F-0 precisely within single syllables, but rather on a supra-segmental level in the context of prosody.
