Abstract
An audio processing system searches for information reports or updates (such as traffic, weather, time, sports, news, and the like) broadcast over one or several radio stations. The search is based on at least one keyword (such as "traffic", "weather", "time", "sports", "news" depending on the desired report) being preselected by the user, and being entered into the audio processing system. While speech recognition software used by the audio processing system scans the radio station for the requested information report, the user may listen to other audio sources (a CD, a tape, another radio station broadcast, etc.) without being required to monitor (that is, listen to) the information content from those audio sources. Once the requested information report is detected based on the entered keyword used in the radio broadcast, the audio processing system switches its audio output to the radio station transmitting the desired broadcast, such that the user can timely and conveniently listen to the traffic, weather, time, sports, and/or news reports or updates.
