An acoutic assessment system of dysphonia, which is hereafter called acoustic voice assessment system, has been developed. The hardware setup for the system is either a personal computer (PC) with a special apparatus which has been newly developed to perform voice input/output and fast signal processing, or a PC with a commercially available sound board. The two setups are able to realize the same function for the voice assessment except that the latter lacks the ability of making voice range profile. The system allows the user to make the assessment quite easily, since it takes a full advantage of Windows on a PC.The voice assessment data obtained from the voice assessment system can be directly utilised for further analyzes using various statistical software packages which are now commercially available on the Windows.Voice assessment can be performed in two different modes : a routine mode and a research mode. In the routine mode, the acoustic assessment is automatically made once a sustained vowel is input to the system. In the research mode, on the other hand, the user can analyze and evaluate a voice sample with a large variety of acoustic analysis tools on a step-by-step basis. The tools include not only acoustic measurements relevant to the assessment of dysphonia, but also various fundamental speech analysis methods such as sound spectrogram, formant and pitch measurement, FFT/LPC spectrum display. A speech synthesis module is also implemented to perform a rather sophisticated assessment of dysphonia as well as the normal voice.The voice assessment system can be used at voice clinics and voice laboratories.

本研究开发了一种发声障碍的声学评估系统，以下简称声学嗓音评估系统。该系统的硬件设置是一台带有新开发的专用设备的个人计算机（PC），以执行语音输入/输出和快速信号处理，或者是一台带有商用声卡的PC。这两种设置都能够实现相同的功能，为语音评估，但后者缺乏的能力，使语音范围的轮廓。由于该系统充分利用了PC机上的Windows操作系统，用户可以很容易地进行评估。从声音评估系统获得的声音评估数据可以直接用于使用各种统计软件包进行进一步分析，这些软件包现在可以在Windows上购买。声音评估可以在两种不同的模式下进行：常规模式和研究模式。在常规模式下，一旦持续元音输入到系统，声学评估就自动进行。另一方面，在研究模式中，用户可以逐步地用各种各样的声学分析工具分析和评估语音样本。这些工具不仅包括与发音障碍评估相关的声学测量，而且还包括各种基本的语音分析方法，如声谱图、共振峰和音高测量、FFT/LPC频谱显示。语音合成模块也实现了一个相当复杂的评估发声障碍以及正常的声音。语音评估系统可以在语音诊所和语音实验室使用。
