PURPOSE: A handsfree for voice recognition is provided to drive a desired electric device by voice information inputted by a user and automatically perform a cellular phone call without directing pushing a button of a cellular phone. CONSTITUTION: A switch unit(10) has a record switch(11) operated for recording a voice, an execution switch(12) for executing recorded contents, and a handsfree mode switch(13) for selecting a handsfree. A handsfree module(20) has a microcomputer(21) for executing an internally set program according to an inputted signal, and an A/D converting unit(22) for converting a voice signal inputted from a microphone(30) into a digital signal and outputting the digital signal. A voice reproducing unit(23) outputs a voice signal stored in the microcomputer(21) by the operation of the reproducing switch(12) of the switch unit(10). An ECU(Engine Control Unit)(100) connects to an output terminal of the microcomputer(21) and drives an electronic device in a vehicle or a cellular phone by a voice signal of a user. A voice information device(90) has a code converting unit(40) for connecting to an output terminal of the handsfree module(20) and coding the digital signal of the A/D converting unit(22), a database unit(50) for storing the digital signal, and a buffer unit(60) for buffering stored data and outputting the buffered data to the outside. The voice information device(90) has a comparing unit(70) for comparing the data outputted from the buffer unit(60) with the digital signal outputted from the A/D converting unit(22), and a signal output unit(80) for receiving a signal outputted from the comparing unit(70) and outputting the received signal so that the electronic device of the vehicle is driven through the microcomputer(21). 본 발명은 사용자가 입력한 음성정보에 의해 원하는 전기장치가 구동됨과 동시에 휴대폰을 직접 손으로 전화버튼을 누르지 않더라도 자동으로 휴대전화 통화가 이루어질 수 있는 음석인식용 핸즈프리에 관한 것이다.
