Disclosed is a method for eliminating audio feedback and echo in a headset of a mobile device connected to the headset which includes a first head having a first speaker unit and a second head having a second speaker unit and a microphone, wherein the method is characterized by including the steps of: monitoring an audio signal received through the microphone; and blocking a channel applied to the second speaker unit of the headset when a waveform corresponding to audio feedback or echo is detected in the received audio signal through the monitoring. Accordingly, noise from the outside can be effectively screened, and also, a user's voice can be sufficiently captured in order to prevent audio feedback and echo from occurring at the source, so that clean sound can be provided to the user and voice recognition accuracy can be increased when the method is applied to a voice recognition device. |
