偏离函数 meaning in English

departure function

A central bias function and an arithmetic of pitch detection based on central bias function were proposed for the transition sound , which cannot be detected by the traditional arithmetic of pitch calculation
摘要针对传统的基音估计算法不能适用于过渡音的问题，提出中心偏离函数及基于中心偏离函数的基音周期检测算法。
The results show that the method using bias function and time - domain clipping to search pitch period can overcome shortcomings of the traditional , reduce false decision and raise the estimation precision
