Claim 9:
10. A control method of a voice recognition device by a processor comprising:
detecting whether a content reproducing device including a voice output unit is present;
analyzing whether a specific characteristic component is included in a voice signal input into a voice input unit when presence of the content reproducing device is detected;
recognizing a voice by executing voice recognition processing of the voice represented by the voice signal input into the voice input unit when it is detected that the voice signal does not include the specific characteristic component;
instructing a response to a response operation unit that operates in response to a recognized voice; and
performing control not to execute the voice recognition processing of the voice represented by the voice signal input into the voice input unit or perform control not to instruct the response operation unit about an instruction content by the voice recognized by executing the voice recognition processing, when it is analyzed that the voice signal includes the specific characteristic component,
wherein the specific characteristic component is an artificial waveform component superimposed on the voice signal by a content signal corrector at a predetermined time interval.
