| 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. |
