Hands-free device

摘要

A hands-free device disposed in a vehicle identifies a speech direction of an outgoing voice when a hands-free call operation is received. The device extracts callee information from the outgoing voice provided by an occupant to identify a portable communication terminal. In particular, the portable communication terminal is identified when the callee information extracted is registered in a telephone book data of the portable communication terminal. When the speech direction of the outgoing voice is identified as a driver side, the portable communication terminal identified is linked to the driver as a driver-linked terminal. Accordingly, a call being received by a portable communication terminal that is linked to the driver is performed as a hands-free call, whereas a call being received by a portable communication terminal not linked to the driver is not performed as a hands-free call.

主权项

1. A hands-free device disposed in a vehicle for performing a hands-free call for a portable communication terminal, the portable communication terminal including a telephone book data stored therein, the hands-free device comprising:
a communication unit being communicably coupled to the portable communication terminal and receiving the telephone book data from the portable communication terminal; a memory unit storing the telephone book data received by the communication unit; a voice output unit having a speaker for outputting a receiving voice of the hands-free call; a voice input unit having at least two microphones for inputting a outgoing voice of the hands-free call; an operation input unit receiving a hands-free call start operation; a speech direction identification unit identifying a speech direction of the outgoing voice inputted by the voice input unit when the hands-free call start operation is received by the operation input unit; a terminal identification unit identifying the portable communication terminal being used for the hands-free call when the hands-free call start operation is received by the operation input unit; and a control unit performing a link process linking the portable communication terminal identified by the terminal identification unit with a driver as a driver-linked terminal when the speech direction of the outgoing voice is identified as a driver side by the speech direction identification unit, wherein the control unit performs the hands-free call when a call being received is through the driver-linked terminal and does not perform the hands-free call when the call being received is not through the driver-linked terminal.
