Abstract

A system for enabling a user of a communication device to both handle an incoming call and originate an outgoing call without having to touch the communication device, by way of exchange of voice messages with the communication device. The system is operative for receiving a signal produced by a microphone associated with the communication device and for processing this signal in an attempt to detect at least one of a plurality of spoken commands potentially contained therein. The plurality of spoken commands comprises at least one spoken call handling command and at least one spoken call origination command. In response to detecting a spoken call handling command, the system causes handling of an incoming call destined for the communication device in accordance with the detected spoken call handling command. In response to detecting a spoken call origination command, the system causes an attempt to establish an outgoing call using the communication device in accordance with the detected spoken call origination command.
