一种应用于移动终端的语音盲分离算法

A Blind Speech Separation Algorithm for Mobile Terminal

盲分离算法被广泛应用于语音信号处理领域中。为改善移动终端的通话质量,提出了一种新的语音盲分离预处理方案,应用频域复随机梯度算法,分离出移动终端待传的主语音信号,从而使其它干扰语音得到抑制。模拟和实际录音的实验结果表明,该方法对改善通话质量有明显的效果。

Blind source separation algorithms are widely used in speech signal processing. In order to improve call quality of mobile terminal, a new scheme for speech signal process is proposed in this paper. By using a frequency complex stochastic gradient algorithm, the speech signal to be transmitted is separated from the mixed speech signal. As a result, the interference speech signal is cancelled. The results of simulations for both synthesizing speech signals from computer and real-world speech signals show that the proposed approach can improve call quality obviously.
