听自己的讲话对语言学习和保持准确的发音很重要。例如，语言后获得性耳聋的人通常表现出言语产生的许多方面的逐渐恶化。在这份手稿中，数据提出了解决的声音反馈在控制语音基频（F0）所发挥的作用。18名受试者在控制（正常F0反馈）和两个实验条件下产生元音：F0上移和F0下移。在每个实验条件下，受试者在训练期间产生元音，其中他们的F0在没有意识的情况下缓慢移动。在暴露于变换的F0之后，它们的声反馈恢复正常。观察到两种效果。受试者补偿了F0的变化，并显示出负面的后效。当F0反馈恢复正常时，受试者将其产生的F0向与偏移相反的方向修改。结果表明，基频控制使用听觉反馈和参考内部音高表示。这与目前关于言语运动控制的内部模型的工作是一致的。(C)2000年美国声学学会[S0001-4966（00）03009-5]。
Hearing one's own speech is important for language learning and maintenance of accurate articulation. For example, people with postlinguistically acquired deafness often show a gradual deterioration of many aspects of speech production. In this manuscript, data are presented that address the role played by acoustic feedback in the control of voice fundamental frequency (F0). Eighteen subjects produced vowels under a control (normal F0 feedback) and two experimental conditions: F0 shifted up and F0 shifted down. In each experimental condition subjects produced vowels during a training period in which their F0 was slowly shifted without their awareness. Following this exposure to transformed F0, their acoustic feedback was returned to normal. Two effects were observed. Subjects compensated for the change in F0 and showed negative aftereffects. When F0 feedback was returned to normal, the subjects modified their produced F0 in the opposite direction to the shift. The results suggest that fundamental frequency is controlled using auditory feedback and with reference to an internal pitch representation. This is consistent with current work on internal models of speech motor control. (C) 2000 Acoustical Society of America rr. [S0001-4966(00)03009-5].
