Summary:PROBLEM TO BE SOLVED: To provide a voice recognition device which keeps a recognition performance close to the performance of a specific speaker system and is enhanced in convenience by automatically conducting the training. SOLUTION: When recognition words are registered, text information of the recognition words is inputted into a voice synthesis processing section 15, synthesized voice signals that are to be outputted are converted into synthesized sound acoustic data by a synthesized voice sound converting section 19. The data are registered in a word acoustic data storage section 21 in place of the uttering of a speaker in a conventional training. The coincident process for acoustic data in a word recognition section 26 in the voice recognition process, that is conducted after the registration, is conducted for the synthesized sound acoustic data. Thus, the voice recognition device for a specific speaker is realized at a low cost and the convenience which is similar to the convenience of an unspecified speaker system voice recognition device that does not required training can be provided.
