摘要
目的 应用嗓音训练方法改善职业用声者发音并验证其有效性.方法 选择31例有嗓音症状但无声带器质性病变的职业用声者作为研究对象接受为期4周的嗓音训练.训练的内容包括嗓音卫生教育、改善呼吸支持及增强共鸣等.应用嗓音障碍指数量表、最长发声时间测量及嗓音声学分析进行训练前后的评估.结果 受试者接受嗓音训练后嗓音障碍指数值((-x)±s,以下同)由(33.7±19.2)分降至(18.8±18.4)分,差异具有统计学意义(t=6.14,P<0.05).受试者接受嗓音训练后最长发声时间由(15.5±5.8)s延长至(18.6±6.0)s,差异具有统计学意义(t=-3.43,P<0.05).受试者接受嗓音训练后基频微扰有显著性下降,由0.42%[0.36%;0.62%](中位数[25分位数;75分位数])降至0.35%[0.29%;0.47%],Z=-2.51,P<0.05;而噪谐比、振幅微扰变化无统计学意义.结论 嗓音训练能够减轻职业用声者嗓音障碍症状,降低嗓音障碍程度并增加发音过程呼吸支持的效率,改善嗓音质量.
Objective To explore the effectiveness of voice training on professional voice users with voice disorders. Methods Thirty one professional voice users suffering from voice symptoms without organic disorder were treated with a four-week voice training program, including vocal hygiene education, respiratory training and resonant therapy. Voice handicap index, maximum phonation time, noise to harmonic ratio,jitter and shimmer were compared before and after the training. Results The voice handicap index ((-x) ± s)decreased from 33.7 ± 19. 2 to 18. 8 ± 18.4 after the training and the difference was significant (t =6. 14,P < 0. 05 ). Maximum phonation time ( (-x) ± s) increased significantly from ( 15. 5 ± 5. 8 ) s to ( 18.6 ± 6.0) s (t = - 3.43, P < 0. 05 ). jitter ( M [P25; P75] ) decreased significantly after the training from 0. 42%[0.36%; 0.62%] to0.35% [0.29%; 0.47%] (Z= -2.51, P<0.05), while there was no significant change in shimmer and noise to harmonic ratio. Conclusion Voice training can effectively reduce the vocal symptoms in professional voice users, decrease the handicap degree and increase the respiratory support during phonation, thus improve the voice quality.
