| Abstract(in English) | For robot-human voice communication, accurate speech recognition and a speaker-direction mechanism are necessary. The microphone attached to the robot body receives motor and mechanical noises directory. The direct noises are often larger than human voices and fatally degrade the speech recognition rate. This paper describes a new method for detecting the speaker direction based on On-and-Off microphone combination. The system searches for the spectral elements of "on-mic" voice in the "off-mic" channels. The segregated power ratio or the time delay between the "off-mic" channels is used for detecting the speaker direction. Experiments show that the proposed method effectively improves the direction detection accuracy during the robot move. |
