采用以汉语普通话为母语的听音人,对模拟仿真得到的具有不同客观语言清晰度参数的声学信号进行语言清晰度主观评价,获得汉语和英语的主观语言清晰度得分,分析比较了它们与语言传输指数STI的关系及其差异.结果表明：汉语和英语语言清晰度得分随STI增大而增加;采用韵律测试字表进行测试时,母语为汉语普通话的听音人听汉语时的语言清晰度得分比听英语时的高;而采用HINT句表进行清晰度测试时,当STI较高时,汉语句子的可懂度比英语的高,而当STI较低时,英语句子的可懂度比汉语的高.

Subjective speech intelligibility scores of Chinese and English are obtained through the sucjective evaluation of simulated room acoustical signals with different objective speech intelligibility parameters by a native standard Chinese listener.Then,the relationships and their difference between the scores and the speech transmission index STI for Chinese and English are analyzed.The results show that Chinese and English speech intelligibility scores increase with STI,that Chinese speech intelligibility scores are higher than English ones for the rhyme test words under the same conditions with native standard Chinese listener,and that the same circumstance occurs at high STI but opposite result is obtained at low STI for HINT sentences.
