Abstract
Methods and apparatus to present a video program to a visually impaired person are disclosed. An example method comprises receiving a video stream and an associated audio stream of a video program, detecting a portion of the video program that is not readily consumable by a visually impaired person, obtaining text associated with the portion of the video program, converting the text to a second audio stream, and combining the second audio stream with the associated audio stream.
