Claims

[Scope of utility model registration request]

The audio data analysis section consists of a microphone that captures audio, a bandpass filter that analyzes the frequency of the captured audio, and an A/D converter that converts analog quantities into digital quantities, and the analyzed data is registered. In a voice recognition system that includes a voice recognition judgment unit that determines whether or not the voice data is equivalent to the voice data that is being used, and if it is equivalent, issues an output command based on the voice command, a registration number is stored in the voice data memory unit for registration. A voice recognition device characterized in that a combination of and voice data is registered, and recognition determination is normally performed only when the two match.
