Patent number: 7747434Abstract: A system and method that integrates automated voice recognition technology and speech-to-text technology with automated translation and closed captioning technology to provide translations of “live” or “real-time” television content is disclosed. It converts speech to text, translates the converted text to other languages, and provides captions through a single device that may be installed at the broadcast facility. The device accepts broadcast quality audio, recognizes the speaker's voice, converts the audio to text, translates the text, processes the text for multiple caption outputs, and then sends multiple text streams out to caption encoders and/or other devices in the proper format.
