APPARATUS AND METHOD FOR GENERATING NOISE ADAPTIVE ACOUSTIC MODEL INCLUDING DISCRIMINATIVE NOISE ADAPTIVE TRAINING FOR ENVIRONMENT TRANSFER

摘要

An apparatus and a method for generating a noise adaptive acoustic model including discriminative noise adaptive training for environment transfer are provided to apply a voice recognition system to a noise environment effectively by using a voice recognition method. Voice studying data(201) reflects various noise environments by high-capacity audio data elementarily used for sound type model learning. A noise reduction unit(203) removes various noise components which are included in the voice studying data. A noise adaptive training technique unit(205) learns the voice studying data by the acoustic model training method. The learned acoustic model is set up as a basis acoustic model parameter(207). Voice data(211) for environmental adaptation is a small amount of voice data collected in the environment to which a voice recognition system is applied.
