Simultaneous measurements were made of voice, oral air flow, and nasal air flow for two speakers producing seven repetitions of 12 differing contexts containing Vowel + Nasal + Oral Consonant sequences in a search for the temporal pattern of nasal coarticulation. Analysis indicated a rather stereotyped degree of overlap of nasal air flow during the oral consonant, about 36% of the duration of the oral consonant. Carryover of nasal air flow into the oral consonant appears to reflect mechano-inertial limitations of a sluggish velum.
对两名说话者进行了同步测量，测量内容包括语音、口腔气流和鼻腔气流。这两名说话者对包含元音+鼻音+口腔辅音序列的12种不同语境重复了7次，以探寻鼻腔协同发音的时间模式。分析表明，在发口腔辅音期间，鼻腔气流的重叠程度相当固定，约占口腔辅音时长的36%。鼻腔气流延续到口腔辅音中似乎反映了软腭运动迟缓的机械惯性限制。
