A real-time sound localization/separation system for near-field sound sources was constructed and evaluated in a real office environment. As for the sound localization, the experimental results showed that the direction of the two sources was estimated with high accuracy while the range of the sources was estimated with moderate accuracy. As for the sound separation, a recognition rate of 70% for an on-line recognizer on a network and of 90% for an off-line recognizer were achieved, respectively.
