| 目的：探讨维吾尔语脑卒中构音障碍患者元音声学特征，分析维吾尔语构音异常运动的特点。方法：纳入2020年1月~2021年12月我科住院康复的维吾尔语脑卒中后存在构音障碍的患者26例和正常人30例，朗读维吾尔语8个元音，分析比较元音共振峰F1、F2的频率、元音空间面积(VSA)和元音清晰度指数(VAI)的差异。结果：病例组元音/i、u/的F1高于对照组（P＜0.05）。病例组元音/a、u/的F2高于对照组（P＜0.05），元音/ε、e、、i、y/的F2低于对照组（P＜0.05）。维吾尔语脑卒中构音障碍患者的VSA、VAI小于对照组（P＜0.05）。结论：维吾尔语脑卒中后构音障碍患者VSA减小、VAI降低，元音发音呈集中趋势，舌运动范围减少，位置不正确，主要在舌前后运动范围缩小，导致发音不清晰。 |

| Objective: To explore the vowel acoustic characteristics in XinJiang Uyghur patients with post-stroke dysarthria and analyze the characteristics of abnormal articulation. Methods: From January, 2020 to December, 2020, 20 patients with post-stroke dysarthria and 20 healthy controls were asked to read Uygur vowels /ɑ, ε, e, , o, I, u, y/, and the F1, F2, the vowel space area (VSA), vowel articulation index (VAI) were measured. Results: The F2 of vowels ɑ and u in the case group was higher than that in the control group (P<0.05). The F2 of vowels /ε, e, , i,y/ in the case group was lower than that in the control group (P<0.05). For the vowel pronunciation /i, u/, the F1 in the case group was significantly higher than that in the control group (P<0.05). The VSA and VAI were significant less in the Uyghur patients with post-stroke dysarthria than in the controls (P<0.05). Conclusion: The vowel production is impaired in the Uyghur patients with post-stroke dysarthria, the VSA and VAI decrease, the pronunciation of vowels tends to be concentrated, the range of tongue motion is reduced, and the position is incorrect, which impacts the speech clarity. |
