摘要
A system and method for evaluating performance of a microphone for long-distance speech recognition, which enables a robot to receive and respond to voices. A robot, which includes a network robot, must correctly recognize speech in order to recognize the user and to perceive its surroundings, objective evaluation criteria are required for choosing a microphone to be used in the robot. The methods include measuring a degree of attenuation of the voice, measuring a degree of distortion of the voice, and simultaneously measuring the degree of attenuation of the voice and the degree of distortion of the voice. A standard for the choice of a microphone, which can be digitalized, for a speech recognition function of a robot, permits choice of a microphone which has good sensitivity and can pick up voices without distortion when used at a large distance.
