最近的研究发现，当说话时，受试者通过改变他们的声音基频（F-0）来补偿感知到的音高偏移，从而对语音听觉反馈的音高扰动做出反应。长的反应延迟（150-200 ms）表明，它们可能太慢，以帮助在线控制与音节到音节的基础上的词汇音调相关联的局部音高轮廓模式。在本研究中，我们引入了音高转移听觉反馈的母语为汉语普通话的人，而他们产生的双音节序列/ma ma/与不同的音调组合在一个自然的讲话速度。语音F-0反应延迟（100-150毫秒）的音高扰动短于音节持续时间在其他地方报道。响应幅度从静态音调期间的50美分增加到动态音调制作期间的85美分。反应潜伏期和峰值时间减少短语涉及F0的动态变化。在需要精确、动态控制F0的任务中，较大的响应幅度和较短的等待时间和峰值时间表明，用于调节语音F0的这种自动系统可能是任务相关的。这些结果表明，听觉反馈可能被用来帮助调节语音Fo在生产的双调普通话短语。(C)2004年，美国声学学会。
Recent research has found that while speaking, subjects react to perturbations in pitch of voice auditory feedback by changing their voice fundamental frequency (F-0) to compensate for the perceived pitch-shift. The long response latencies (150-200 ms) suggest they may be too slow to assist in on-line control of the local pitch contour patterns associated with lexical tones on a syllable-to-syllable basis. In the present study, we introduced pitch-shifted auditory feedback to native speakers of Mandarin Chinese while they produced disyllabic sequences /ma ma/ with different tonal combinations at a natural speaking rate. Voice F-0 response latencies (100-150 ms) to the pitch perturbations were shorter than syllable durations reported elsewhere. Response magnitudes increased from 50 cents during static tone to 85 cents during dynamic tone productions. Response latencies and peak times decreased in phrases involving a dynamic change in F0. The larger response magnitudes and shorter latency and peak times in tasks requiring accurate, dynamic control of F0, indicate this automatic system for regulation of voice Fo may be task-dependent. These findings suggest that auditory feedback may be used to help regulate voice Fo during production of bi-tonal Mandarin phrases. (C) 2004 Acoustical Society of America.
