以往的研究对声学线索负责的清音-清音的区别在预应力英语爆破强调清音开始时间的重要性，相对于爆破释放（VOT）。英语中的浊塞音通常有一个短的VOT（小于20-30毫秒），并且在声音开始之后存在显著的共振峰转换。另一方面，处于预加应力位置的清塞音具有相对长的VOT（大于约50毫秒），并且共振峰转换基本上在发声之前完成。我们的合成语音实验比较了VOT的作用，以及在浊音开始后是否存在显著的共振峰转换作为浊音-无声区分的线索。数据表明，这两个线索之间存在显着的交易关系。语音开始后快速频谱变化的存在或不存在会在感知音素边界的位置产生高达15毫秒的变化，以绝对频率测量。
Previous research on acoustic cues responsible for the voiced‐voiceless distinction in prestressed English plosives has emphasized the importance of voicing onset time with respect to plosive release (VOT). Voiced plosives in English normally have a short VOT (less than 20–30 msec) and a significant formant transition is present following voice onset. Voiceless plosives in prestressed position, on the other hand, have relatively long VOT's (greater than about 50 msec) and the formant transitions are essentially completed prior to voice onset. Our experiments with synthetic speech compare the role of VOT and the presence or absence of a significant formant transition following voicing onset as cues for the voiced‐voiceless distinction. The data indicate that there is a significant trading relationship between these two cues. The presence or absence of a rapid spectral change following voice onset produces up to 15‐msec change in the location of the perceived phoneme boundary as measured in terms of absolut...
