Then the speech signal is pitch adjusted according to this pitch contour, where the original signal with time varying pitch period is converted to a signal of constant pitch period.
然后根据这一轨迹对语音信号进行“基音调整”，将原始的、具有时变基音周期的信号转化为一个具有恒定基音周期的信号。
The SNR in public environment of whispered speech is lower than normal speech and the former hasn't pitch period and its formants are not obvious, so whispered speech enhancement is harder.
相对于正常语音来说，耳语音在公共场合的信噪比较低，而且没有基音周期，共振峰不明显，所以耳语音增强具有一定的难度。
In this paper, we present a new method, which is entitled "the Function of Area Difference", to detect the pitch period of speech signal.
本文提出了一种新的检测基音周期的方法：“面积差函数法”。
