A blind separation algorithm of speech signal based on spatial cues

Based on spatial cues, a blind separation algorithm of speech signal was proposed. In time-frequency domain, extract the spatial cues of speech signal, which are ITD and ILD, then construct the 2D diagram by distribution density of ITD and ILD. Next, mark the time-frequency binary masking and using this technique separate the source in time-frequency domain. Finally, I-STFT is used to transform the separated source back to time domain, and realize the blind separation algorithm of speech signal. To summarize, the proposed algorithm will give a new prospect to the research filed of blind separation of speech.
