For the pitch misgrouping problem caused by no voicing decision in Meddis'pitch extracting method for concurrent speech signals, referring to voicing decision for single speech signal, basing on the analysis of the voicing charater of concurrent speech signals, we present a voicing decision method in pitch extracting for concurrent speech signals. Double periodic degree and frequencies group's distribution degree are introduced for voicing decision of concurrent speech signals.

针对Meddis的基于听觉心理生理的混叠语音基频提取算法中不分清浊音所导致的语音基频错判问题，借鉴了单语音清浊音判断的方法，基于对混叠语音的清浊性能的分析，提出了混叠语音基频提取中的清浊音判断算法，提出了判断混叠语音周期性的双周期度及判断频带组周期性的分布度两个指标，用于混叠语音基频提取中的清浊音判断。
