We review evidence suggesting that deaf speakers do not move their articulators toward the following open posture throughout closure and report results from a preliminary cinefluorographic study. Two prelingually deaf and two hearing speakers produced two different strings of alternating heterogeneous monosyllables as though speaking in time with a metronome (the so-called P-center task). Events traditionally associated with vowel production appeared evenly timed throughout the productions, and, in general, the deaf speakers performed similarly to the hearing speakers. We relate the results to Fowler's (1983) interpretation of the P-center phenomenon as an indicant of continuous vowel production.
我们回顾了相关证据，这些证据表明聋人说话者在整个发音闭合过程中不会将其发音器官朝着后续的开放姿势移动，并报告了一项初步的电影荧光造影研究结果。两名语前聋人和两名听力正常的说话者说出了两组不同的交替异质单音节序列，就好像跟着节拍器同步说话一样（即所谓的P中心任务）。传统上与元音发音相关的事件在整个发音过程中出现的时间均匀，并且总体而言，聋人说话者的表现与听力正常的说话者相似。我们将这些结果与福勒（1983年）对P中心现象的解释联系起来，该现象被视为连续元音发音的一个指标。
