2) pitch of concurrent speech signals
混叠语音基频
3) voice plus
音频叠加
4) overlap audio
重叠音频
5) overlapping speech
混叠语音
1.
Wavelet transform is very effective for picking up the pitch detection from a single source,but there is no effective way to obtain the pitch information from the pitch detection in overlapping speech with multi-sources.
小波变换对单一信号源的基音提取非常有效,但在多音源混叠语音的基音提取中则无法有效地获得基音信息。
2.
This paper puts up a method suitable for multi pitch detecting under overlapping speech signals environment.
本文提出了一种在混叠语音信号中检测各自语音分量基音信息的方法 。
3.
From the ideas of computational auditory scene analysis, this paper studies how to pick out the independent pitches and harmonics of each source from the overlapping speech signals.
从计算声场景思想出发，研究了如何从混叠语音中提取各源信号基音及谐波分量的方法，在此基础上根据语音信号正弦模型重建各语音分量，从而实现混叠语音分离。
6) frequency aliasing
频谱混叠
1.
The research of frequency aliasing of Contourlet transform based on directional filter banks;
基于方向滤波器组的Contourlet变换频谱混叠特性研究
2.
It shows that we can avoid the frequency aliasing by changing the direction of t.
得出了当被测物体的频谱呈现非圆形分布时,可以采用改变投影的光栅条纹的方向消除频谱混叠,达到在不增加条纹密度和图像获取装置的分辨率的情况下减小或消除基频和零频间的混叠。
