PURPOSE: A voice signal output apparatus for a display device and a method thereof are provided to supply an optimized voice signal for a user by applying optimized equalizer function according to a preset voice mode. CONSTITUTION: A voice signal analysis part(20) acquires a frequency bandwidth level value by analysis of a voice signal on an external interface part(10). A control part sets the frequency bandwidth level value for compensation of the input voice signal by the analysis between frequency bandwidth reference values according to a preset voice mode and a bandwidth level value. A voice signal compensation part(50) compensates the voice signal according to the compensation values on frequency band compensation values.
