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: To explore the role of speech intelligibility in the evaluation of postoperative laryngeal phonological function. Methods: The frequency spectrum of 40 patients with laryngeal cancer after operation was analyzed by U SSA computer speech spectrum analysis system, meanwhile the speech intelligibility was tested and the correlation coefficient was calculated. Results: The speech intelligibility of quantified subjective indicators had no correlation with the objective indexes such as sound time, fundamental frequency, harmonic ratio, frequency perturbation quotient and amplitude perturbation quotient (P> 0.05), P means the absolute irrelevant possibility Sex). Conclusion: The objective indexes can not completely replace the subjective indexes. Especially for patients who have a large range of laryngectomy and are strongly required to speak, the speech intelligibility can be used as an important evaluation index of pronunciation function.
