言语测听汉语系统的开发

Development of Chinese Speech Test System

目的为了使我国的言语测听临床工作与国际听力研究接轨,研制一套适应我国耳病患者的汉语语言训听系统。方法作者利用Visual Studio2008、Access2003、DirectX9开发了汉语言语测听系统,系统包括受试者管理、言语测听、测试表管理、数据管理、系统设置5个功能模块。结果本测听系统受试者管理模块可以添加、修改、删除、检索、导出患者的各项信息;言语测听模块可以进行言语识别阈和识别率的测听,测试完毕系统可以自动存储分析受试者的测听结果 ,并绘制出受试者的PI曲线;测试表管理模块可以查看、添加、修改、删除测试表及测试项的文字、关键字、声音;数据管理模块可以查看、筛选、导出受试者的测试结果 ;系统设置模块中,用户可以设置测试表的选择方式、播放方式、自动播放时间间隔、刺激声及噪声。结论本系统改变了传统的手工测听模式,简便了言语测听工作,缩短了测试时间,降低了测试成本,可以为我国的言语测听提供一个统一的平台,进一步促进言语测听的科学化、标准化、信息化。

Objective To make speech audiometry clinical work,comply with information society development,and to integrate with the international hearing study,the authors developed a computerized speech test system. Methods The system used Visual Studio 2008,Access 2003 and DirectX 9. The system included five functions：listener management,speech test,list management,data management and system settings. Results By using listener management,the tester was able to search,review,add,revise and delete listener＇s information. The speech test included the measurement of a speech recognition score（SRS） and speech recognition threshold（SRT）,in an open set test. At the end of a list or series of tests,both the stimuli and corresponding subject responses were recorded onto the hard drive for each test item. In addition,the system could report and print the results in a graphic format. Using list management,testers could review,add,revise and delete lists or items such as characters,key words and sounds. By using data management,the results could be reviewed,searched and exported. According to the test condition and the preferences,tester could set system. Conclusion The study changed the traditional manual audiometry mode,might provide a unified platform for speech audiometry in China,and contribute to scientific,standardized,and informationally developed speech audiometry.
