偏离函数 meaning in Chinese

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
研究结果表明：采用所提出的中心偏离函数和时域削波方法相结合来搜索基音周期，能够有效地克服传统方法的不足，降低误判率，提高基音周期的估计精度。
