PROBLEM TO BE SOLVED: To provide a voice recognition device which can register only the vocabularies actually used by a user as the target vocabularies for voice recognition. SOLUTION: The signal processing unit 1 has an external memory 15 storing legitimate names as the target vocabularies for voice recognition. It creates other synonymous words from the legitimate names through the signal processor 11, and registers them in the external memory 15 as the vocabularies for voice recognition after evaluating how often they are used. It registers only the synonymous words estimated to be actually used often as the target vocabularies for voice recognition. COPYRIGHT: (C)2008,JPO&INPIT
