Abstract
An electronic appliance capable of preventing errors in speech recognition and improving the speech recognition rate. The appliance has a speaker for outputting an audio signal, a sound receiver for receiving external sound, a detector for detecting watermark information inserted into the sound received by the sound receiver, a sound remover for removing the audio signal including the watermark information detected by the detector, a speech recognizer for identifying the sound and giving a command corresponding to the recognized sound, and a control unit for receiving the command and controlling the operation corresponding to the received command. The improper operation of an electronic appliance can be prevented, during sound recognition, as the sound output from the speaker is removed and only the user'"'"'s speech is recognized.
