讨论了通过房间平方脉冲响应计算调制转移函数从而导出语言传输指数预测厅堂的语言清晰度的方法,并对该方法中存在的问题作了详细的探讨。%The method of predicting speech intelligibility with speech transmission index STI is discussed in this paper. The STI is derived from the modulation transfer function MTF determined by the squared pulse response. Some problems of predicting speech intelligibility are also discussed in detail.
