Abstract
Features described herein relate to providing the capability to playback audiovisual content in a comprehensible manner at a rate adjustable by the viewer. For example, if a viewer wishes to watch a one hour news program, but the viewer only has thirty minutes to view the program, playback of the program at twice the rate, but in a comprehensible manner is provided. To provide the playback of the video at the adjustable rate, substitute audio is generated by adding or removing audio content without changing the playback rate of the audio. The video at the adjusted playback rate and the substitute audio at the normal playback rate may have the same duration and in some embodiments, may be presented synchronously.

- and
- providing, with the video portion at the modified playback rate, the alternative audio at the first playback rate.
A method comprising:
- determining, by a computing device, a video portion, wherein the video portion is to be output at a modified playback rate that is different from a first playback rate of the video portion;
