A speech audiometric trial is described for testing the degree of hearing loss and its pathogenesis. Test vowels and distorted speech sounds were synthesized with DECtalk for use in speech audiometric tests. Results showed that 100% articulation can be obtained with undistorted synthesized vowels, while reasonable articulation scores can be obtained with distorted synthetic speech signals. This method could solve some of the problems inherent in use of recorded natural Japanese speech sounds as acoustic stimuli during otological examinations.
本文描述了一种用于测试听力损失程度及其发病机制的言语听力测试方法。使用DECtalk合成测试元音和畸变语音，用于言语听力测试。结果表明，使用未畸变的合成元音可获得100%的清晰度，而使用畸变的合成语音信号也可获得合理的清晰度得分。该方法可以解决耳科检查中使用录制的自然日语语音作为声学刺激所固有的一些问题。
