There has been recent growing interest in the analysis of various electronically recorded signals as potential tools for objective assessment of vocal dysfunction. In the past, analysis of such signals required an expensive multitrack FM recorder, mainframe computer system, customized software, and significant time commitment. This report describes an adaptation of commercially available components that allow digital recording of multiple electronic signals, storage of data, and subsequent signal analysis using an inexpensive personal microcomputer system. Commercially available software for manipulation and examination signals is discussed as adapted for examination of glottographic and acoustic signals. The relatively inexpensive availability of similar computer systems will, hopefully, encourage assessment of the clinical applications of objective techniques of voice quality.
最近，人们越来越关注对各种电子记录信号的分析，将其作为客观评估嗓音功能障碍的潜在工具。过去，分析此类信号需要昂贵的多轨调频录音机、大型计算机系统、定制软件，并且需要投入大量时间。本报告描述了一种对市售组件的改装，该改装允许使用廉价的个人微机系统对多个电子信号进行数字记录、数据存储以及后续的信号分析。文中讨论了适用于声门图和声信号检测的市售信号处理和检测软件。希望类似计算机系统相对低廉的价格能促使人们对嗓音质量客观评估技术的临床应用进行评估。
