摘要
本文介绍了用调制转移函数(MTF)预测通信系统中语言清晰度的原理和实验装置。由于在不同带宽和不同信噪比组成的42种通信条件下得到的STI值与主观的清晰度得分的百分数存在极密切的相关关系,所以MTF方法是预测通信系统中语言清晰度的一条新途径。
In this paper the principle for predicting speech intelligibility with STI and experimental device are recommended. The STI values measured in 42 different communication conditions with combination of different bands and different signal to noise ratio have closely correlated with the subjective intelligibility score in percentage. MTF method is a new way for predicting speech intelligibility in communication systems.
