Rhythm Analysis of Teacher's Speech in Classroom

In this paper, we propose a novel method for classroom teaching evaluation by combining with speech analysis. The real time voice signals are transformed into discrete digital signals through hardwares, and we can access and deal with them in MATLAB. During the procedures, a lot of experiments and simulations have been made. The enrichment of rhythm, tone fluctuation and passion are judged by setting some evaluation criteria, and a preliminary conclusion about the teaching effects is provided.
