Abstract
A voice enhanced phone card which allows a caller to place a call by voice activated dialing only when the caller desires it is presented. A caller places a call using a standard calling card switch number and enters a predetermined service code. The voice enhanced phone card system recognizes the service code, and using known telephone switching capabilities, switches the call to a voice activated dialing system at a main feature point in the voice activated dialing system call flow. The call is then connected to a destination using the voice activated dialing routine.
