Claim 7:
8. A voice recognition device comprising:
a voice input unit into which a voice signal is input;
a voice analyzer configured to analyze whether a specific characteristic component is included in the voice signal input into the voice input unit;
a voice recognizer configured to recognize a voice represented by the voice signal input into the voice input unit;
a response instruction unit configured to instruct a response to a response operation unit that operates in response to the voice recognized by the voice recognizer;
a controller configured to control the voice recognizer not to execute voice recognition processing by the voice recognizer or to control the response instruction unit not to instruct the response operation unit about an instruction content by the voice recognized by the voice recognizer, when the voice analyzer analyzes that the voice signal includes the specific characteristic component; and
a reproducing device detection unit configured to detect that a content reproducing device including a voice output unit reproduces a content,
wherein the voice analyzer analyzes whether the voice signal input into the voice input unit includes the specific characteristic component when the reproducing device detection unit detects that the content reproducing device reproduces a content, and
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.
