Abstract

A system and method for allowing a communication device to accepts voice commands from a user. The voice commands can include commands to execute or dial key sequences or commands to control device functionality. Voice commands are received from a user of the communication device, indicating a command to be carried out by said communication device. The commands are interpreted and executed by the communication device.

interpreting said received audible information as a voice command instructing the communication handset to dial said requested key sequence entry;

dialing said requested key sequence entry; and

exiting said voice command mode, wherein exiting said voice command mode is performed in response the occurrence of the expiration of a time period, passing of a period of silence, or completion of a recognized command or command sequence.

2. The method of claim 1, wherein said entering a voice command mode is performed in response to a manual operation performed by said user or in response to the occurrence of one or more programmed events.

3. The method of claim 2, wherein said programmed events comprise at least one of the group of dialing an identified number, receiving a call from an identified calling number, or receiving an incoming call in an idle mode.

4. The method of claim 1, wherein said interpreting comprises employing speech recognition techniques to interpret a received voice command to determine a key or key sequence the user is instructing the communication handset to dial.

5. The method of claim 1, wherein said recognized command or command sequence comprises a voice-mail message reply or forward command.

6. The method of claim 1, wherein said dialing comprises generating one or more DTMF tones and transmitting said generated tone or tones to said system.

7.
