Auditory feedback has been suggested to be important for voice fundamental frequency (F0) control. The present study featured a new technique for testing this hypothesis by which the pitch of a subject's voice was modulated, fed back over earphones, and the resultant change in the emitted voice F0 was measured. The responses of 67 normal, healthy young adults were recorded as they attempted to ignore intermittent upward or downward shifts in pitch feedback while they sustained steady vowel sounds (/a/) or sang musical scales. Ninety-six percent of subjects increased their F0 when the feedback pitch was decreased, and 78% of subjects decreased their F0 when the pitch feedback was increased. Latencies of responses ranged from 104 to 223 ms. Results indicate people normally rely on pitch feedback to control voice F0.
听觉反馈被认为对嗓音基频（F0）控制很重要。本研究采用了一种新的技术来检验这一假设，即调制受试者的嗓音音高，通过耳机进行反馈，并测量发出的嗓音F0的相应变化。记录了67名正常、健康的年轻成年人在持续发出稳定元音（/a/）或唱音阶时试图忽略音高反馈的间歇性上升或下降变化时的反应。当反馈音高降低时，96%的受试者提高了他们的F0，当音高反馈增加时，78%的受试者降低了他们的F0。反应潜伏期为104至223毫秒。结果表明，人们通常依靠音高反馈来控制嗓音F0。
