Abstract
An apparatus, program product, and method restrict access to objectionable audio content in an audio or audio/video transmission using sound recognition. Sound recognition may be performed, for example, to detect and control access to objectionable non-spoken audio content, e.g., by detecting violent sounds such as screams, explosions, gun shots, sirens, punches, kicks and/or other non-spoken content such as sexually-suggestive sounds. In addition, occurrences of objectionable audio content detected in an audio transmission may be tracked so that access to the audio transmission may be controlled responsive to the identification of multiple occurrences of objectionable audio content. Furthermore, access control over detected objectionable audio content in an audio transmission may result in inhibition of access to a program associated with the audio transmission.
