摘　　要：目的探讨计算机频谱分析系统在艺术嗓音客观评估方面的规律及标准。方法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例艺术嗓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)、基频标准差(F_0SD)、基频微扰(jitter)、振幅微扰(shimmer)、噪声/谐和比(noise to harmonic ratio,NHR)以及基频、音强、音长、音高。结果艺术嗓音组与对照组比较,F_0、F_0SD、jitter、shimmer以及基频、音长、音强和音高具有显著性差异(P<0.05)。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,可为艺术嗓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 assessment of artistic voice objective. Methods Audio signal spectrum analysis was performed in 60 cases of artistic voice group and control group by CSL-4150B voice acoustic assessment system, and each group of the fundamental frequency （ F0 ）, audio frequency standard deviation （FoSD） , jitter, shimmer, noise to harmonic ratio （NHR） , fundamental, the length （domain）, sound intensity （energy） and pitch was analyzed. Results There were significant differences in F0, FoSD, length, sound intensity and pitch between art voice group and control group （P 〈 0. 05）. Conclusion Application of CSL-4150B computer voice spectrum analysis system to obtain the physical acoustics parameters of each audio detection provides effective, objective, and quantitative indicators for the assessment, diagnosis and treatment of artistic voice.
