摘　　要：目的探讨计算机频谱分析系统在职业语音客观评估方面的规律及标准。方法采用计算机频谱技术即应用CSL-4150B语音声学评估分析系统,对60例职业语音组及对照组的音频信号进行频谱检测并分析各组音频的基频(F_0)、共振峰、带宽(DB、B_1、B_2、B_3)、辅音起始时间(voice onset time,VOT)、以及音高、音强、音长等,同时对于语图谐波、共振峰成分特征及变化规律进行频谱分析。结果职业语音组与对照组比较,共振峰F_0、F_1、F_2、F_3、DB、B_1、B_2、B以及音长、音强、音高以及语图有显著性差异。结论应用CSL计算机语音频谱分析系统CSL-4150B检测获取音频的物理声学参量及语图,可为职业语音的评定及诊治提供量化的有效客观指标及依据。Objective To discuss rules and standards of computer spectrum analysis system in the field of professional voice objective assessment. Methods Audio signal spectrum analysis was performed in 60 cases in professional audio voice group and control group by CSL-4150-b voice acoustic assessment system, and the fundamental frequency （F0） , each group of audio and formant, bandwidth （DB, B1, B2, B3） , consonants starting time （voice onset time VOT） and pitch, the sound intensity （energy）, length （domain）, and the figure of harmonic, for- mant composition characteristics and change rule were analyzed. Results There were signifi- cant differences in formant F0, F1, F2, F3, DB, B1, B2, B, sound intensity and duration, pitch and figure between two groups （P 〈0. 05）. Conclusion Application of CSL CSL-4150- b computer voice spectrum analysis system to obtain the physical acoustics parameters of each audio detection and figure provides effective, objective, and quantitative indicators and basis for the assessment, diagnosis and treatment of professional voice.
