In the same time, a sliding pitch analysis window method is used, so it can reduce the pitch detection error in non-stationary speech segments with irregular pitch.

同时又采用了滑动窗的方法，使得对基音周期不规则的不平稳的语音段进行基音周期估计时的误差减小。

Taking the sliding window processing, the maneuver detection algorithm is real-time without any time delay.

同时通过采用逐点更新法，可实时进行机动检测。
