摘　　要：语音信号的基音估计算法多年来一直是人们关注的问题。属于时域法的基于短时自相关函数的基音估计方法以其算法简单、计算量小而成为人们首选的算法。论文在此法的基础上,提出了一种基于时域自相关平方函数的基音周期估计方法。通过实验仿真表明,该方法简单易行,基音周期估计的准确性比较高。Speech pitch estimation is a problem attended by people for many years.Pitch estimation in time-domain based on correlated function of short-time is a preferred algorithm because of simple algorithm and little calculating times.So the paper brings forward a method of pitch estimation in time-domain based on correlated square function.Through experiment simulation,the method is simple and pitch estimation is much exact.
