  • Patent number: 7191117
    Abstract: A method for generating subtitles for audiovisual material received and analyses a text file containing dialogue spoken in audiovisual material and provides a signal representative of the text. The text information and audio signal are aligned in time using time alignment speech recognition and the text and timing information are then output to a subtitle file. Colors can be assigned to different speakers or groups of speakers. Subtitles are derived by receiving and analyzing a text file containing dialogue spoken by considering each word in turn and the next information signal, assigning a score to each subtitle in a plurality of different possible subtitle formatting options which lead to that word. The steps are then repeated until all the words in the text information signal have been used and the subtitle formatting option which gives the best overall score is then derived.

  • Patent number: 6226615
    Abstract: Text to be spoken by a speaker, e.g. a newsreader, and held in a store, is displayed on a display which is seen by the speaker through a partially-reflecting mirror 16 mounted in front of a television camera. The text is scrolled up as the speaker speaks, this being achieved automatically by a controller. The controller recognizes the spoken speech picked up by a microphone, using speech recognition techniques, and matches the spoken text with the stored text to be spoken. The speed at which the text is spoken is thus determined and used by positioning circuit to adjust the rate at which the text scrolls up on the display. If the speech recognition fails, the text continues to be changed at a rate dependent upon the previous rate of change.
