PURPOSE: A method for automatically recognizing a voice system is provided to let a user easily use a television by automatically setting up a voice system via a specific program. CONSTITUTION: A method for automatically recognizing a voice system comprises the steps of obtaining a weight using PLL(Phase Locked Loop) after tuning a signal by automatic search or ATF(Automatic Fine Tuning)(S1), respectively switching SAW(Surface Acoustic Wave) filters embedded in a television system(S2), obtaining weights of acoustic signals of respective systems by analyzing the base band acoustic signals(S3), obtaining weights of respective systems by FFT(Fast Fourier Transform) for discriminating the difference between a noise and a signal(S4) by switching the SAW filters of all embedded voice systems(S5,S6), and setting up the system having the largest value as a voice system of the presently tuned program by adding up all weights(S7).
