Abstract

A voice recognition apparatus according to the embodiment includes a first user input unit for receiving a first user command; a second user input unit for receiving a second user command; and a control unit for executing a specific function according to a combination of the first and second user commands input through the first and second user input units.

Claims

1. A voice recognition apparatus comprising:

a first command input unit configured to receive an input signal;

a second command input unit configured to receive and recognize a voice;

a wireless communication part configured to transmit control signals to a peripheral device; and

a control part configured to determine whether the input signal is a first command;

wherein if the control part determines that the input signal is a first command, the control part is configured to activate the second command input unit if the second command input unit is in an inactivation state; and

wherein if the control part determines that the input signal is not a first command, the control part is configured to perform a function according to the input signal;

wherein if the input signal is determined to be the first command, the control part is configured to output a control signal shutting off an audio output of the peripheral device through the wireless communication part;

wherein the control part is configured to;

determine whether the first command is continually received through the first command input unit,

if the first command is continually received through the first command input unit, voice recognition sensitivity of the second command input unit is increased; and

if the input signal is not continually received through the first command input unit, the voice recognition sensitivity of the second command input unit is decreased; and

wherein the activation of the second command input unit is maintained while the input signal is not received through the first command input unit.

2. A method of recognizing a voice, the method comprising:

inactivating a voice recognition function;

receiving an input signal through a first command input unit;

determining whether the input signal is a first command;

transmitting a control signal shutting off an audio output of a peripheral device through a wireless communication part if the input signal is determined to be the first command;

activating the voice recognition function if the input signal is determined to be the first command;

performing a function according to the input signal if the input signal is determined not to be a first command;

determining whether the first command is continually received through the first command input unit;

if the first command is continually received through the first command input unit, increasing voice recognition sensitivity of the voice recognition function to a first level;

if the first command is not continually received through the first command input unit, decreasing the voice recognition sensitivity of the voice recognition function to a second level;

wherein the activation of the voice recognition function is maintained while the input signal is not received through the first command input unit, and

wherein the first and second levels are respectively settable and changeable.
