Outline of Final Research Achievements |
A system that can recognize speech and environmental sound and background sound into a robot with a microphone-array has been developed. It detects the directions of the sound sources, and then separated into each sound for directions. The subsystem is realized by the method of selecting the recognizer depending on whether speech or environmental sounds, after the separated sound is determined whether speech or non-speech. In addition, the remaining sound subtracting all the directional sounds is handled as the background sound. A background sound recognizer is also developed. Finally, the total system has been able to simultaneously recognize speech and environmental sound and background sound.
