Abstract

A radio telephone apparatus having a voice recognition function. A voice dial mode may be set for a predetermined time period in response to the actuation of a switch, whereby address data corresponding to an operator'"'"'s utterances within a predetermined time period after the switch is actuated may be broadcast to a base station over a radio channel. The operator may confirm the address data to be broadcast by checking one or more indications which are visually or acoustically provided before the address data is broadcast.
