Blind source separation based on the timedelayed decor
relation, which had been extended to a convolved mix
ture problem, is evaluated and implemented in a DSP
system. The evaluation is conducted using the data
recorded in an anechoic chamber and those in a listen
ing room with moderate reverberation. The crosstalks
and the scores of automatic speech recognition are mea
sured. The hardware consists of dual DSPs and a host
PC. The results of the benchmark is shown.
