听觉反馈影响人类语言的产生，正如使用快速音高和响度变化的研究所证明的那样。反馈也被调查使用逐步操纵共振峰在适应研究与低声说话。在这里报道的工作中，在浊音语音的试验中，稳态孤立元音的第一个组成峰出乎意料地发生了变化。这是通过为此目的开发的实时峰跟踪和滤波系统实现的。元音/epsilon/的第一个构成峰被100%地操纵到/ae/或/I/，参与者通过改变他们的产量来做出回应，平均F1补偿分别高达应用形成峰位移的16.3%和10.6%。估计补偿在刺激开始后小于460毫秒开始。这里发现的快速峰补偿表明，F0和峰的听觉反馈控制是相似的。(c) 2006年美国声学学会。
Auditory feedback influences human speech production, as demonstrated by studies using rapid pitch and loudness changes. Feedback has also been investigated using the gradual manipulation of formants in adaptation studies with whispered speech. In the work reported here, the first formant of steady-state isolated vowels was unexpectedly altered within trials for voiced speech. This was achieved using a real-time formant tracking and filtering system developed for this purpose. The first formant of vowel /epsilon/ was manipulated 100% toward either /ae/ or /I/, and participants responded by altering their production with average F1 compensation as large as 16.3% and 10.6% of the applied formant shift, respectively. Compensation was estimated to begin < 460 ms after stimulus onset. The rapid formant compensations found here suggest that auditory feedback control is similar for both F0 and formants.
