之前的作者已经证实，幼儿的停止辅音发声比成人更受到限制，并将其归因于不成熟的声道压力管理。与言语空气动力学相关的身体发育持续到青春期，这表明辅音发声的发展也可能持续到学龄期。本研究探讨了女性、5 岁和 10 岁儿童的停止辅音发声与口内压力轮廓之间的关系。每个年龄段的八位说话者录制了声间 /p b/ 的作品。根据 Muller 和 Brown [语音和语言：基础研究和实践进展，N. Lass 编辑（学术，麦迪逊，1980 年），第 1 卷，对停止辅音发声和 delta 进行了测量，该测量旨在表征停止时口内压力增加的时间过程。 4，第 318-389 页]。年龄对停止辅音发声和 Delta 的影响在统计上并不显着，但 Delta 和停止发声之间的相关性通常不太显着，有时在儿童中相反，这提供了不成熟的空气动力学控制的一些证据。目前的数据以及 Muller 和 Brown 的数据也表明，Delta 测量可能会产生一些矛盾的值，这表明在评估口内压力时变特征的方法方面需要做更多的工作。
Previous authors have established that stop consonant voicing is more limited in young children than adults, and have ascribed this to immature vocal-tract pressure management. Physical development relevant to speech aerodynamics continues into adolescence, suggesting that consonant voicing development may also persist into the school-age years. This study explored the relationship between stop consonant voicing and intraoral pressure contours in women, 5 year olds, and 10 year olds. Productions of intervocalic /p b/ were recorded from eight speakers at each age. Measures were made of stop consonant voicing and delta, a measure designed to characterize the time course of intraoral pressure increase in stops, following Muller and Brown [Speech and Language: Advances in Basic Research and Practice, edited by N. Lass (Academic, Madison, 1980), Vol. 4, pp. 318-389]. Age effects for stop consonant voicing and delta were not statistically significant, but correlations between delta and stop voicing were less often significant and sometimes reversed in the children, providing some evidence of immature aerodynamic control. The current data, as well as those of Muller and Brown, also show that the delta measure may yield some paradoxical values, indicating that more work is needed on methods of assessing time-varying characteristics of intraoral pressure.
