目的　为探索客观有效的异常语音评价方法 ,应用计算机语音分析系统 ( CSL )分析各种类型患者的异常语音。方法　 8例筛选患者 ,咽喉摩擦音、先天性腭咽闭合功能不全、腭化构音和正常构音各 2例 ,其中男性 4例 ,女性 4例 ,平均年龄 18岁。被检敏感音为 /z/、/c/、/s/,直接输入计算机语音工作站 ,存盘后对音声图像进行定量分析和比较。结果　各种类型语音的音声图像各有其特征 ,其频谱、辅音起声时间和共振峰各不相同。结论　 CSL综合了语图仪和计算机技术 ,可图像化和定量分析声音 ,在目前是一种较好的研究手段 Objective To explore an objective and effective method for evaluating abnormal speech, computer-assisted speech analysis system (CSL) was used to analyze the abnormal speech of various types of patients. Methods Totally 8 patients were selected, including 2 cases of throat rubbing tone, congenital velopharyngeal insufficiency, 2 cases of palatalization and normal acoustics, including 4 males and 4 females, with an average age of 18 years. Sensitive sound was detected / z /, / c /, / s /, directly into the computer voice workstation, save the sound image after the quantitative analysis and comparison. Results The audio images of various types of speech have their own characteristics, the spectrum, consonants, the onset time and the resonance peak vary. Conclusion CSL integrates a speech plotter and computer technology to visualize and quantify sound, which is a good research tool at present
