一种话音激活检测算法的DSP实现和性能分析

An Voice Activity Detection Algorithm and Implementation on DSP

本文介绍了一种基于短时能量和短时过零率的话音激活检测算法,在TMS320VC5416 DSK开发平台上实现了该算法,并与ITU-TG.729B、G.723.1话音编码方案中所采用的话音激活检测算法作比较,最后得出该算法具有一定实用价值的结论。

This paper introduces the algorithm of voice activity detection based on the chip_time energy and chip_time zero crossing and implementation on TMS320VC5416 DSK platform,We analyze and compare the results with ITU-T G.729B and G.723.1 speech coding protocol and get a conclusion.
