A Real-Time Blind Speech Separation Algorithm Based on the Time-Delay Estimation
【摘要】 目前盲分离算法相当复杂,对硬件的运算速度要求很高,无法满足实时性要求。根据盲信号分离的原理和特点,提出了一种基于延时估计的实时语音盲分离算法,大大提高了盲解分离的运算速度,主客观评价表明其具有很好的分离效果,证明了算法的有效性。
【Abstract】 The presented blind source separation algorithms are very complicated for the hardware with the real-time operation. According to the principles and characteristics of the blind source separation, a real-time blind speech separation algorithm which can improve both the separation speed and the separation performance is proposed. The simulating results show that the proposed algorithm is effective.
