PROBLEM TO BE SOLVED: To properly recognize voice picked up by a nondirectional microphone. SOLUTION: The voice signal from a nondirectional microphone 15-4 is so delayed that voice signals of sound which arrive from a nondirectional microphone 15-3 and the nondirectional microphone 15-4 as shown by the thick arrow in the figure and disturb voice recognition are in phase with each other. The difference between the voice signal of voice picked up by the nondirectional microphone 15-3 and the delayed voice signal picked up by the nondirectional microphone 15-4 is calculated and according to the voice signal obtained as a result, the voice recognition is performed.
