Using cinefluorography, this investigation evaluated how the bilabial and dorsal stop closure postures of 2 hearing and 5 deaf speakers varied with vowel context. The jaw and tongue body postures of the hearing and the 2 most intelligible deaf speakers altered with the identity of the following vowel. This did not occur consistently for the remaining deaf speakers. The results concur with a previous suggestion (Tye, Zimmerman, & Kelso, 1983) that some speakers who learn speech without audition may develop a different articulatory coordination than hearing speakers. Discovering these differences may lead to a general account for many of their intelligibility deficits.
本研究使用电影荧光造影术，评估了2名听力正常者和5名聋人说话者的双唇音和软腭塞音闭合姿势如何随元音语境而变化。听力正常者以及2名最易听懂的聋人说话者的下颌和舌体姿势会随着后续元音的不同而改变。而其余聋人说话者并非始终如此。研究结果与之前的一项提议（泰伊、齐默尔曼和凯尔索，1983年）一致，即一些通过非听觉方式学习言语的说话者可能会形成与听力正常者不同的发音协调方式。发现这些差异可能会为他们许多可懂度缺陷提供一个总体解释。
