语言传输指数 STI和语言可懂度指数 SII为当前语言可懂度的两个主要客观评价体系.对 STI和 SII计算模型和测量结果的研究表明,二者并没有本质上的区别,测量结果的差别也主要是由采用的具体方法不同造成的；STI和SII的汉语语言可懂度主、客观评价关系曲线差别也不大,都可以用来对汉语的语言可懂度进行客观评价.但考虑到 SII 的测量过程更为复杂,在传统建筑声学等领域的应用也不具有优势,以及 ANSI S3.5对测量条件限制的相对宽松可能会带来数据之间的可比性降低等因素,STI 更适用于对汉语语言可懂度的客观评价.

STI (speech transmission index)and SII (speech intelligibility index)are the two main obj ective rating methods for speech intelligibility.Their calculation models and measured data are examined,and the results show that there is no fundamental difference between them except those caused by the specific process.In terms of their relationship with Chinese speech intelligibility scores, there is also very little difference between STI and SII,and it has been demonstrated that both STI and SII can be used as an obj ective rating method for Chinese speech intelligibility.Considering that the SII measurement process is more complex,there is less advantage of using it compared to STI in conventional architectural acoustics measurements.In addition,it has been revealed that the relative loose restrictions on measurement conditions in ANSI S3.5 may reduce the comparability between different measurements.Overall,it seems that STI is more suitable as the obj ective rating method of Chinese speech intelligibility.
