摘要
教室是典型的语言声厅堂,良好的言语交流条件至关重要,言语可懂度是表征语音传输质量的重要参量。传统的客观声学参量不能对教室的语音传输质量进行综合性的评价。随着言语可懂度的客观评价参量语音传输指数(STI)最新标准的发布,使用言语可懂度评价教室音质成为当前的研究热点。基于探讨传统评价方法与言语可懂度评价方法的关系,本文对使用言语可懂度评价教室音质的研究进行了梳理与分析,并指出了STI用于客观评价教室音质的发展方向。
The classrooms are typical speech sound auditoriums where good communication conditions are essential. Speech intelligibility is an important parameter to guarantee the quality of speech transmission. Traditional objective acoustic parameters cannot provide a comprehensive assessment of the quality of speech transmission in the classroom. With the release of the latest standard of the speech intelligibility objective assessment of parameterized speech transmission index （STI）, the application of speech intelligibility in evaluating classroom sound quality has become the current research hotspot. This study combed and analyzed the recent research progress of speech intelligibility evaluation in classrooms and points out the development direction of speech intelligibility in evaluating sound quality of classrooms.
