Measurements were made of intraoral air pressure associated with bilabial closure durations of VCV syllables in sentence-like frames of increasing length for nine deaf and nine matched normal hearing chidren. Results demonstrated significantly longer absolute closure durations at all utterance lengths for the deaf, but with the same relative decrease in closure durations with increases in utterance length for both groups. The deaf children showed lower peak intraoral air pressure values with more variability than the normal children. In addition, the deaf children had longer air-pressure pulse durations than did the normals. Clinical application of these findings to speech management are discussed.
对9名失聪儿童和9名听力匹配的正常儿童进行了测量，测量内容为在长度不断增加的类似句子框架中，与VCV音节双唇闭合时长相关的口腔内气压。结果表明，在所有话语长度下，失聪儿童的绝对闭合时长显著更长，但两组的闭合时长都随着话语长度的增加而相对减少。与正常儿童相比，失聪儿童的口腔内气压峰值更低，且变化更大。此外，失聪儿童的气压脉冲持续时间比正常儿童更长。本文还讨论了这些研究结果在言语管理中的临床应用。
