音调周期抽取，采用逆滤波和降低取样率的平均幅差函数方法。
Extraction of pitch period: An inverse filtered-simplified-AMDF method is proposed.
随之，当收缩周期开始时，每一个部分又回到你最初开始舞蹈时所安排的声音与音调的运动中。
Then as the contraction cycle begins, each part moves towards the original movement of sound and tone orchestrated as one first began the dance.
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。
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.
不同的语音音调主要体现在语音的基音周期和共振峰频率的差别上。
The different pitch and the different formant frequency decide the different pitch-scale.
不同的语音音调主要体现在语音的基音周期和共振峰频率的差别上。
