Abstract:

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. ccording 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.
