Responding to a call to action contained in an audio signal
Abstract:
An audio signal is monitored to detect the presence of a call to action contained therein. Addressing information is automatically extracted from the call to action and stored on a storage medium. An electronic message responding to the call to action may be automatically prepared, or a contact field may be automatically populated for inclusion in a contact list. The audio signal may be digitized or obtained from a broadcast transmission, and the process may be performed by a mobile communication device, a central system, or a combination thereof.
