PURPOSE: An apparatus for changing a voice of an optical disk regenerator of an accompaniment device is provided to convert a voice without a noise by performing a conversion of voice by a mike using a data distributor and a mute circuit without an A/V decoder. CONSTITUTION: A main control unit(111) controls a total system of an optical disk reproducing device and a calculates data. A main memory(112) stores and outputs data of the main control unit(111). A front control unit(113) is interfaced and communicated with the main control unit(111) and a serial in/output(SIO), and controls digital/analogue converters(117, 118, 119). A front panel unit(114) displays a control result of the front control unit(113). An A/V decoder(115) receives a control of the main control unit(111) and separates and decodes audio and video signals. A decoder memory(116) transmits/receives to the A/V decoder(115), and stores and outputs decoding data. The first DAC(117) receives audio data of front L, R channels outputted from the A/V decoder(115), and converts the audio data into analogue data. The second DAC(118) receives audio data of rear L, R channels outputted from the A/V decoder(115), and converts the audio data into analogue data. The third DAC(119) receives audio data of center and sub channels outputted from the A/V decoder(115), and converts the audio data into analogue data. The first mixer(120) mixes analogue audio signals outputted from the first DAC(117), the second DAC(118) and the third DAC(119). Also, a mike(121), a mike amplification unit(122) and a mike sensor are provided. A data distributor(129) receives channel information having a voice from the front control unit(113) and transmits the information to a mute circuit. The first mute circuit(130) senses a signal outputted from the data distributor(129) and connects to an output terminal of the first DAC(117) in parallel and mutes the voice. In addition, the second and third mute circuits(131, 132), the second mixer(124), a mixer audio outputting unit(125), a video encoder(126) and a video output unit(127) are provided.
