摘要: 目的 探讨脑卒中后构音障碍患者的元音产出特征改变及其与言语清晰度之间的关系。 方法 2019年10月至2020年1月,选择脑卒中后构音障碍患者19例(脑卒中组)和健康成人18例(对照组),朗读一段语音均衡材料,分析元音产出声学特征,包括下颌距、舌距、F2i/F2u、元音空间面积(VSA)、元音清晰度指数(VAI)、F1变异性、F2变异性;两名言语治疗师对言语清晰度进行主观评判。将元音产出特征与言语清晰度进行相关性分析。 结果 脑卒中组舌距、F2i/F2u、VSA、VAI和言语清晰度小于对照组(|t| > 2.268, P < 0.05);F2变异性大于对照组(t = 2.375, P < 0.05)。脑卒中组的F2i/F2u (r = 0.465)、VAI (r = 0.488)、F2变异性(r = -0.504)均与言语清晰度相关(P < 0.05)。 结论 脑卒中后构音障碍患者元音产出存在缺陷,表现为构音运动异常、各元音呈集中趋势、元音稳定性较差,脑卒中患者元音产出特征与其言语清晰度相关。

Abstract: Objective To explore the characteristics of vowel production of dysarthria after stroke, and the relationship between vowel production and speech clarity. Methods From October, 2019 to January, 2020, 19 patients with post-stroke dysarthria and 18 healthy controls were asked to read a short essay to extract vowels, and measured the jaw distance, tongue distance, F2i/F2u, vowel space area (VSA), vowel articulation index (VAI), F1 and F2 variability, and speech clarity. The correlation between vowel production and speech clarity were analyzed. Results Tongue distance, F2i/F2u, VSA, VAI, and speech clarity were less in the patients than in the controls (|t| > 2.268, P < 0.05), while F2 variability was more (t = 2.375, P < 0.05). F2i/F2u (r = 0.465), VAI (r = 0.488) and F2 variability (r = -0.504) were correlated to speech clarity (P < 0.05). Conclusion The vowel production impaired in patients with post-stroke dysarthria, featured as abnormal articulatory movements, concentration of vowels and poor stability of vowels, which impacts the speech clarity.
