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.
