本研究提出了一个假设，即说话人对元音对比的辨别越准确，说话人产生的元音对比就越明显。言语产生和感知的措施，收集了19个年轻的成年美国英语发言人。在生产实验中，发言者重复鳕鱼，反刍，谁的，和胡德在载波短语在正常，清晰，快速的速度。记录发音运动和相关的声学信号，产生/a/和/Lambda/之间以及/u/和/nu/之间的对比距离的测量。在辨别实验中，根据一名男性和一名女性说话者的作品，合成了七组自然发音的刺激，从鳕鱼到反刍，从谁到胡德。连续体，然后提交给每个19个扬声器的标签和歧视的任务。与此假设相一致的是，发言者的歧视分数高于中位数产生更大的声学对比度比发言者的歧视分数或低于中位数。语音产生和感知之间的这种关系与语音产生的模型是相容的，在该模型中，元音的发音运动主要是在听觉空间中计划的。(C)2004年，美国声学学会。
This study addresses the hypothesis that the more accurately a speaker discriminates a vowel contrast, the more distinctly the speaker produces that contrast. Measures of speech production and perception were collected from 19 young adult speakers of American English. In the production experiment, speakers repeated the words cod, cud, who'd, and hood in a carrier phrase at normal, clear, and fast rates. Articulatory movements and the associated acoustic signal were recorded, yielding measures of contrast distance between /a/ and /Lambda/ and between /u/ and /nu/. In the discrimination experiment, sets of seven natural-sounding stimuli ranging from cod to cud and who'd to hood were synthesized, based on productions by one male and one female speaker. The continua were then presented to each of the 19 speakers in labeling and discrimination tasks. Consistent with the hypothesis, speakers with discrimination scores above the median produced greater acoustic contrasts than speakers with discrimination scores at or below the median. Such a relation between speech production and perception is compatible with a model of speech production in which articulatory movements for vowels are planned primarily in auditory space.
