本文通过对30例因腭咽闭合不全而行二次咽成形术的患者进行语音评价,分析了手术前后辅音清晰度的变化,结果发现咽成形术后各辅音清晰度均有显著改善,尤以爆破音最为明显,其后依次为塞擦音、摩擦音及鼻辅音。作者认为腭咽闭合不全对爆破音发音有直接影响,而擦音的发音异常则主要与不良语音习惯有关。 In this paper, 30 cases of velopharyngeal pharyngeal closure due to velopharyngeal pharyngeal angiography evaluated patients before and after the analysis of consonants sharp changes in the results found that the consonant clarity after pharyngeal angiography have significantly improved, especially The most obvious plosive sound, followed by rubbing sound, rubbing sound and nasal consonant. The author believes that velopharyngeal insufficiency has a direct impact on the sound of the plosive sound, while the pronunciation of the fricative anomaly is mainly related to bad voice habits.
