In order to investigate control of voice fundamental frequency (F0) in speaking and singing, 24 adults had to utter the nonsense word ['ta:tatas] repeatedly, while in selected trials their auditory feedback was frequency-shifted by 100 cents downwards. In the speaking condition the target speech rate and prosodic pattern were indicated by a rhythmic sequence made of white noise. In the singing condition the sequence consisted of piano notes, and subjects were instructed to match the pitch of the notes. In both conditions a response in voice F0 begins with a latency of about 150 ms. As predicted, response magnitude is greater in the singing condition (66 cents) than in the speaking condition (47 cents). Furthermore the singing condition seems to prolong the after-effect which is a continuation of the response in trials after the frequency shift. In the singing condition, response magnitude and the ability to match the target F0 correlate significantly. Results support the view that in speaking voice F0 is monitored mainly supra-segmentally and controlled less tightly than in singing.
为了研究说话和唱歌时嗓音基频（F0）的控制情况，24名成年人被要求反复说出无意义的词['ta:tatas]，同时在特定试验中，他们的听觉反馈频率向下偏移100音分。在说话条件下，目标语速和韵律模式由白噪声组成的节奏序列指示。在唱歌条件下，序列由钢琴音符组成，受试者被要求匹配音符的音高。在两种条件下，嗓音F0的反应潜伏期约为150毫秒。正如预测的那样，唱歌条件下的反应幅度（66音分）大于说话条件下的反应幅度（47音分）。此外，唱歌条件似乎延长了后效应，即频率偏移后试验中反应的延续。在唱歌条件下，反应幅度与匹配目标F0的能力显著相关。结果支持这样一种观点，即在说话时，嗓音F0主要通过超音段进行监测，并且控制不如唱歌时严格。
