拍摄了4名正常受试者的高速荧光电影，这些受试者在正常的说话水平和产生速率下说含有鼻音辅音（N）、辅音（C）和元音（V）的各种组合的英语句子。单词和音节的边界被设计成以各种方式跨越序列。根据逐帧描记，测量软腭运动和咽闭合。结果表明，广泛的预期cocarticulation软腭运动对腭咽开口的CVN和CVVN序列，软腭运动对开放开始在所有情况下，在接近初始元音和一些腭咽开口观察到所有元音。对于NC和NCN序列，软腭运动关闭的辅音通常开始在前面的鼻音，这样一些软腭关闭期间观察到所有爆破音和摩擦辅音使用。这些结果直接反驳了CV型音节是共构音的最小单位的假设。
High‐speed cinefluorographic films were taken of four normal subjects speaking English sentences containing various combinations of nasal consonants (N), consonants (C), and vowels (V) at normal speaking levels and rates of production. Word and syllable boundaries were designed to fall across the sequences in various ways. From frame‐by‐frame tracings, measures of velar movement and velopharyngeal opening were made. Results indicate extensive anticipatory coarticulation of velar movement toward velopharyngeal opening in CVN and CVVN sequences such that velar movement toward opening began during the approach to the initial vowel in all cases and some velopharyngeal opening was observed on all vowels. For NC and NCN sequences, velar movement toward closure for the consonant usually began during the preceding nasal such that some velar closure was observed during all plosive and fricative consonants used. These results directly contradict the hypothesis that a CV‐type syllable is the minimal unit of coarticu...
