PVR-based system and method for TV content control using voice recognition

摘要

A system and method for controlling the content displayed on a TV based on recognizing a viewer's voice. A microprocessor in a PVR that is associated with the TV can recognize a viewer's voice and allow only appropriate programming to be played on the TV. Thus, for example, violent or sexually explicit programs or commercials can be screened from a viewer who is recognized as being a young person.
