Patent Number: 8,818,459

Title: Hands-free device

Abstract: 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.
