pitch period

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。

A new speech analysis method based on pitch period is presented.

提出了一种新的以基音周期为基础的分析方法。

The algorithm for pitch period search with MBE model is complex in calculation and low flexible.

MBE模型的基音周期搜索算法存在着运算量大,抗噪性能一般等缺点.

The pitch period and the spectral envelope of speech represent acoustical characteristics of the speech signal.

基音周期体现了发声过程肺部气流的周期性,而语音频谱包络是人的声道共振滤波特性在频域中的表现.

For a given corpus to estimate the pitch period.

对给定语料估计其基音周期.

The audio waveform is divided into several pieces according to the pitch period, and then the successive pieces with the same semitone are grouped into one segment.

首先利用基音分析技术将整个音频波形分割为若干基音周期，然后以半音为单位将连续的基音周期组织成音频段落，并在各个段落内部按指定比例进行缩放。
