摘　　要：维吾尔语口语考试系统,基于C/S结构,由考试系统、考试管理系统等模块组成。应用Socket实现管理机和考试机之间的通信。介绍了维吾尔语口试测试方案和流程,研究了维吾尔语的输入、输出,音频的输入、输出,系统开发平台和运行环境等问题。讨论了在Windows 7下,利用回调函数管理音频数据块和应用低级音频函数进行录音的方法。给出了在录音过程中,采用波形图和柱形图实时显示录音音量大小变化的方法和录音设备故障检测的方法。在维吾尔语口语考试中,应用口语考试系统,取得了成功。The system of Uyghur oral exam,based on C/S structure,is composed of exam system,exam management system and other modules. In the oral exam system,use Socket to realize the communication between management＆#39;s computer and exam＆#39;s computer. In-troduce the methods and processes of Uyghur oral exam. These problems are studied such as the input and output of Uyghur language,the input and output of the audio,the system development platform and running environment. Under Windows 7,the methods are discussed u-sing the callback function to manage audio data block and using the low-level audio functions to record. The algorithms are given how to use waveform graph and bar graph to display the changes of real-time recording volume,and how to detect the fault of recording equip-ment. In the Uyghur oral exam,have achieved success by application of the oral exam system.
