OBJECTIVE
To verify the immediate effect of the flexible resonance tube vocal technique on the oropharyngeal geometry and vocal acoustic parameters of individuals with Parkinson's disease (PD) and to study the correlation between oropharyngeal geometry and the intensity and fundamental frequency (f0) parameters of the voice.
METHODS
Forty individuals participated-20 with PD and 20 healthy individuals, with a mean age of 60.95 (± 5.69) years. There were 10 men and 10 women in each group. All underwent pharyngometric analysis of the vocal tract and voice acoustics parameters before and after use of the vocal technique with a flexible resonance tube.
RESULTS
After the technique, there was a reduction in pharyngeal cavity volume only in females in the healthy group, a reduction in shimmer values in females in both groups and males in PD group and an improvement in noise parameters in females in the PD group. There was a negative correlation between vocal tract volume and intensity, between f0 and vocal tract volume, between f0 and oropharyngeal junction area, between f0 and oral cavity volume as well as a positive correlation between oral cavity length and f0.
CONCLUSION
The vocal technique with the flexible resonance tube applied to individuals with PD improved the subjects' voice quality in the perceptual and acoustic voice parameters. Regarding the oropharyngeal geometry, it was possible to observe its correlation with the parameters of vocal intensity and frequency in the studied population.
目的
验证柔性共鸣管发声技术对帕金森病（PD）患者的口咽几何形状和嗓音声学参数的即时影响，并研究口咽几何形状与嗓音强度和基频（f0）参数之间的相关性。
方法
共有 40 名参与者参与，其中 20 名 PD 患者和 20 名健康对照者，平均年龄为 60.95（±5.69）岁。每组各有 10 名男性和 10 名女性。所有参与者均在使用柔性共鸣管发声技术前后进行了声道的咽测图分析和嗓音声学参数的检测。
结果
技术应用后，健康组女性的咽腔容积减小，两组女性的颤抖值减小，PD 组男性的颤抖值减小，PD 组女性的噪声参数改善。声道容积与强度呈负相关，f0 与声道容积、f0 与咽峡部面积、f0 与口腔容积呈负相关，而口腔长度与 f0 呈正相关。
结论
应用于 PD 患者的柔性共鸣管发声技术改善了患者的嗓音质量，在感知和声学嗓音参数方面都有改善。就口咽几何形状而言，在研究人群中观察到了它与嗓音强度和频率参数之间的相关性。
