Abstract: The present invention relates to a voice recognition system. More particularly, the present invention relates to an apparatus for adapting language model scale to improve voice recognition performance in the voice recognition system. According to the present invention, in case of a voice signal of a low signal-to-noise ratio, a weighted value is applied to the discrimination of a language model. Therefore, recognition performance with regard to noisy environment is improved.

Abstract: Provided is a voice-based completely automated public turing test to tell computers and humans apart (CAPTCHA) method and an apparatus to perform a CAPTCHA procedure using the voice of a human being. The provided method comprises the steps of collecting a plurality of uttered sounds of a user; detecting a start point and an end point of a voice from each of the plurality of collected uttered sounds, and then detecting speech sections; comparing the uttered sounds of the respective detected speech sections with reference uttered sounds, and then determining whether the uttered sounds are correctly uttered; and determining whether the plurality of uttered sounds have been made by an identical speaker if it is determined that the uttered sounds are correctly uttered. Accordingly, the CAPTCHA procedure is performed using the voice of the human being, and thus it can be easily checked whether a human being has personally made a response using a voice online.
