【摘要】 运用SHS（分谐波累加）法可准确地提取单个语音的基音周期，本文将该方法推广运用到重叠语音基音的分离检测，并提出了相应的检测方法．实验证明，本文提出的方法能有效地分离并提取两重叠语音的基者，即使对于基音周期相差较近的两个重叠语音也能取得较好的结果．更多还原

【Abstract】 SHS (Subharmonic Summation) is a approach which can be applied to extract single speech pitchaccurately.In this paper, the approach ahs been extended to overlapping speeches situations to extract and separate pitches of overlapping specches, and a corresponding algorithm has been represented also. Experiments haveshowed that this approach can effectively extract and separtate pitches of two overlapping speeches, on the difference of the two speeches is quite smaall.更多还原
