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。
The system is a collection of voice acoustic analysis, glottic image analysis functions in one laryngeal disease diagnosis system. The software is compiled from the Virtual Instrument Development Language (LabWindows / CVI). Through the instrument of the interface, to achieve a variety of operations and results display. The voice analysis function can collect, store and display the sound signal, and can extract fundamental frequency (F0), frequency perturbation quotient (FPQ), amplitude perturbation quotient (APQ), harmonic noise ratio (HNR) JF) and amplitude shuffling (Shimmer) and other acoustic parameters, but also for three-dimensional sound map analysis; glottic image analysis of the vocal cords vibration images can be static, dynamic display or frame image freeze display; can be intercepted with clinical Diagnostic value of the image for observation and storage; and frame images can be glottal length, glottis area, vocal fold area, lesion size and other parameters extraction and analysis.
