Abstract: Disclosed herein is a voice-based CAPTCHA method and apparatus which can perform a CAPTCHA procedure using the voice of a human being. In the voice-based CAPTCHA) method, a plurality of uttered sounds of a user are collected. A start point and an end point of a voice from each of the collected uttered sounds are detected and then speech sections are detected. Uttered sounds of the respective detected speech sections are compared with reference uttered sounds, and then it is determined whether the uttered sounds are correctly uttered sounds. It is determined whether the uttered sounds have been made by an identical speaker if it is determined that the uttered sounds are correctly uttered sounds. Accordingly, a CAPTCHA procedure is performed using the voice of a human being, and thus it can be easily checked whether a human being has personally made a response using a voice online

Abstract: An apparatus and method for performing asynchronous speech recognition using multiple microphones are disclosed. The apparatus includes a microphone selection unit, a signal-to-noise ratio measurement unit, a speech recognition and verification unit, and a final recognition result output unit. The microphone selection unit selects two or more microphones responsive to a user's voice from among a plurality of microphones distributed around the user. The signal-to-noise ratio measurement unit measures the signal to noise ratios of inputs of the selected two or more microphones. The speech recognition and verification unit performs speech recognition using the input of the microphone having a highest signal to noise ratio, and verifies the speech recognition using the inputs of the remaining microphones. The final recognition result output unit outputs the final recognition results of the user's voice based on the results of the speech recognition and verification unit.
