Abstract: PURPOSE: A system control device using voice recognition is provided so that a user voice can be inputted without being interrupted by a sound source. CONSTITUTION: A sound input unit(1) inputs a voice control command. A voice input sensing unit(11) senses an input of the voice control command, by comparing the voice control command of the voice input unit(1) with an audio signal from a sound source of a system main body. As a result of the comparison, when the voice control command is currently inputted, an input interruption unit(12) interrupts a voice output from the system main body. A voice recognition engine(9) receives the voice control command inputted to the voice input unit(1), and performs voice recognition according to the voice control command. Accordingly, it is possible to prevent voice mis-recognition due to interference between the voice control command of the user and the audio signal from the system main body.
