语言可懂度在喉癌术后发音功能评价中的作用

The Function of Speech Intelligibility in Voice Evaluation after Laryngectomy

目的 :探索语言可懂度在喉癌术后发音功能评价中的作用。方法 :应用 U SSA计算机语图频谱分析系统对 40例喉癌术后患者的发声进行频谱分析 ,同时检测语言可懂度 ,并计算两者间的相关系数。结果 :量化主观指标语言可懂度与声时、基频、谐噪比、频率微扰商和振幅微扰商等客观指标无相关性 (P >0 .0 5 ,P表示绝对不相关的可能性 )。结论 :客观指标不能完全替代主观指标的作用 ,特别是对于那些喉切除范围较大、强烈要求能够说话的患者 ,语言可懂度可以作为发音功能的重要评价指标。

Objective:Our purpose was to study the function of speech intelligibility in voice evaluation after laryngectomy. Methods:We chose 40 patients with laryngeal carcinoma, and made frequency spectrum analysis of their voices with USSA computerized sonagram and frequency spectrum analysis system. We examined their speech intelligibility, and calculated Pearson correlation coefficients simultaneously. Results:The correlation analysis indicated that speech intelligibility had no relativity with maximum phonation time, fundamental frequency, harmonic to noise ratio, pitch perturbation quotient, and amplitude perturbation quotient (P>0.05). Conclusion:Speech intelligibility is an important index of voice evaluation especially for communicating ability. Objective indexes can not take the place of subjective ones totally.
