1. A method of setting controls on a digital communication device operated by an end user participant in a digital content event provided from a digital communication network, the method comprising: operating a tracking control in the digital communication network to track activity of the digital communication device in a context of the digital content event; applying the activity to a content series detector; applying an output of the content series detector to a series gap detector; operating a timer in conjunction with the activity and an output of the series gap detector to form a time-stamped set of ranking controls; attenuating the time-stamped set of ranking controls according to an elapsed time; applying the time-stamped set of ranking controls and content inputs from a digital content manager to operate a ranking control and digital filter to generate a control interface for the digital communication device, the control interface comprising a plurality of individually operable controls; operating a sub-stream filter on the digital content event to generate an extracted digital sub-stream; operating a speech-to-text converter on the extracted digital sub-stream to generate a digital text sequence; applying the digital text sequence to adapt the time-stamped set of ranking controls into adapted ranking controls of the control interface; and configuring the digital communication device with the control interface.
