The following study concerns the acoustic parameters marking the difference between the phonation of children with velar incompetency and a corresponding control group. Population is made of 64 children aged 5 and 6; 32 are in the control group and 32 in the pathological group. Each child was required to repeat several words; 10 vowels and 9 consonants were taken from those words. Acoustic signal was recorded and studied using a standard speech assessment work station. 63 parameters for the vowels and 6 for the consonants were studied. Results showed that the best parameters concerned the vowels and that cepstrum coefficients were an efficient tool to perform the separation of the two groups. On the contrary, formants, voice pitch and jitter did not appear to be efficient enough to do this task. It was, then, deduced a check form for velopharyngeal incompetency, form which will be tested in future work.
以下研究关注的是表明腭功能不全儿童与相应对照组发声差异的声学参数。研究对象为64名5岁和6岁的儿童；32名在对照组，32名在病理组。要求每个儿童重复几个单词；从这些单词中选取10个元音和9个辅音。使用标准语音评估工作站记录并研究声学信号。研究了元音的63个参数和辅音的6个参数。结果表明，最佳参数与元音有关，且倒谱系数是区分两组的有效工具。相反，共振峰、音高和抖动似乎不足以有效地完成这项任务。据此，推导了一种腭咽功能不全的检查表格，该表格将在未来的工作中进行测试。
