PURPOSE: A portable phone accessory and a voice dialing method using the same are provided to implement a voice dialing function through the accessory so that the voice dialing function can be applied to every portable phone. CONSTITUTION: If a button for an audio mode is selected(S201), a microcomputer detects audio information inputted from an audio CODEC(S202). The microcomputer compares the detected voice information with audio reference information stored in a memory, detects command data corresponding to a keypad(S203), and transfers the detected data to a portable phone through a serial port(SIO) and a connector(S204). If dialing is made, the microcomputer checks whether the portable phone is in a call state(S205). If the portable phone is in the call state, the microcomputer maintains an idle state until the call state ends(S206). If the call finishes, the microcomputer enters an audio monitoring mode in order to detect whether an earphone/microphone button is pushed(S207).
