  • Method for enhancing recognition probability in voice recognition systems
    Patent number: 6801890
    Abstract: The invention relates to a method for enhancing recognition probability in voice recognition systems. According to the inventive method, selective post-training of the already stored homonymic term is carried out after inputting a term to be recognized. This makes it possible to improve the speaker-dependent recognition rate even in environments with prevailing acoustic interference.
