目的探讨噪声、振动复合因素下生成语音在听觉效果上的变化及变化规律。方法在安静及信噪比分别为０ｄＢ和－６ｄＢ三种状态下进行清晰度测试，以研究噪声、振动复合因素组、单独噪声组、单独振动组及对照组４个组的语音材料清晰度变化规律。结果和对照组相比，复合因素作用下语音清晰度有明显降低，检验结果非常显著；和单因素相比，多数情况下有显著性变化。研究还发现，清晰度的降低随听音环境的信噪比的降低而变得严重，当信噪比为－６ｄＢ时，清晰度得分低于７０％。结论噪声、振动复合因素对发音人发音的影响，会使通话效果变差，并且在听音环境恶劣时尤为突出。本研究结果对改善航天及军事环境语言通信效果具有重要意义
Objective To investigate the changes and changes of the auditory effects of the generated speech under the compound factors of noise and vibration. Methods Clarity tests were performed under quiet and SNR of 0dB and -6dB, respectively, to study the change of sharpness of speech materials in 4 groups of noise and vibration complex factor group, noise alone group, vibration group and control group law. Results Compared with the control group, the speech intelligibility was significantly reduced under the combination of factors and the test results were very significant. Compared with the single factor, there were significant changes in most cases. The study also found that the reduction in sharpness became worse with a decrease in signal-to-noise ratio in the listening environment, with a sharpness score of less than 70% at a signal-to-noise ratio of -6 dB. Conclusions The influence of noise and vibration compound factors on pronunciation of speaker can worsen the effect of conversation and is especially prominent when listening environment is bad. The results of this study are of great significance for improving the language communication in aerospace and military environment
