摘　　要：本系统是一个集嗓音声学分析、声门图像分析功能于一体的喉疾病辅助诊断系统。软件由虚拟仪器开发语言(LabWindows/CVI)编制而成的。通过仪器化的界面,实现各种操作与结果的显示。嗓音分析功能可进行声音信号的采集、存储、显示,并可提取基频(F0)、频率微扰商(FPQ)、振幅微扰商(APQ)、谐波噪声比(HNR)、频率颤动(JF)和振幅微扰(Shimmer)等声学参数及,还可进行三维声图分析;声门图像分析功能可进行声带振动图像的静相、动相显示或帧图像冻结显示;可任意截取具有临床诊断价值的图像进行观察和存储;并可对帧图像进行声门长度、声门面积、声带面积、病变大小等参数的提取分析。This work is directed at developing a virtual instrument system as an accessorial diagnostic instrument for laryngeal diseases. Programmed with LabWindows/CVI, the system combines the voice acoustic analyzing function with the glottal image measuring function. The voice acoustic analyzing system can sample, store and replay vocal signals; can extract and analyze parameters, including fundamental frequency（F0）, frequency perturbation quotient （FPQ）, amplitude perturbation qtmtient（APQ）, barmonics-to-noise ratio（HNR） ,jitter frequency（JF）, Shimmer; and can do 3D sound graph analysis. The glottal image analyzing system can sample and store the image observed by the laryngostroboscope; can display any phase in one cycle of the vibration of the vocal cords or a slow and continuous movement of vibrating vocal cords; can snap and save the diagnostic frame of image; and can extract the parameters of the image such as the length and area of the glottis, the length and area of the vocal cords and the diseased part.
