Evaluation and Real-time implementation of blind source separation system using time-delayed decorrelation


Blind source separation based on the time-delayed decorrelation, which had been extended to a convolved mixture problem, is evaluated and implemented in a DSP system. The evalutation is conducted using the data recorded in an anechoic chamber and those in a listening room with moderate reverberation. The crosstalks and the scores of automatic speech recognition are measured. The hardware consists of dual DSPs and a host PC. The results of the benchmark is shown.
