为研究不同性别及年龄阶段我国正常成人嗓音的声学特征以及不同发音方式下声带振动的特性，应用计算机语音频谱分析技术对90例20～50岁正常人的嗓音进行了声学参数测量。结果表明：在发最低音、自然舒适音、真声最高音时，各年龄组男女间基频（F0）、频率微扰商（FPQ）、振幅微扰商（APQ）均有显著性差异，F0、FPQ女性大于男性，而APQ男性大于女性。F0与FPQ、APQ之间有显著相关性。真声音域（OCT）在年龄性别间无明显差别。本研究可为临床嗓音的分析评估提供客观的方法和依据。
In order to study the acoustic characteristics of normal adult voice and vibration of vocal cords under different pronunciation styles in different genders and ages, the acoustic parameters of 90 normal adults aged 20 to 50 years were measured by computer speech spectrum analysis. The results show that there are significant differences in the fundamental frequency (F0), frequency perturbation quotient (FPQ) and amplitude perturbation quotient (APQ) between men and women in the lowest bass, natural comfort tone, F0, FPQ women than men, while APQ men than women. There was a significant correlation between F0 and FPQ and APQ. True sound area (OCT) no significant difference between the age and gender. This study can provide an objective method and basis for the analysis and assessment of clinical voice.
