Claim:
A radio receiver comprising: a tuner that provides an audio output for a selected radio station; a voice-only detection mechanism that monitors the audio output of the tuner, and that provides a first output indication when the audio output of the tuner is mostly voice, and that provides a second output indication when the audio output of the tuner is mostly music; a radio processor coupled to the voice-only detection mechanism, the radio processor changing an operational mode of the radio receiver according to the first and second output indications of the voice-only detection mechanism, wherein the radio processor changes the tuner to a different radio station according to the first and second output indications of the voice-only detection mechanism; a spectrum analyzer coupled to the audio output of the tuner, the spectrum analyzer storing a preferred frequency spectrum signature for a radio signal; a second tuner coupled to the radio processor; the radio processor scanning available radio stations using the second tuner to locate a program that matches the preferred frequency spectrum signature within predetermined criteria, and changing to a radio station that matches the preferred frequency spectrum signature when the first output indication is received.
