Speech Recognition for Live ClosedCaptioning ABSTRACT This paper describes three realtime closedcaptioning systems using speech recognition that are in practical use and a new system under study. The first system employs thedirect method whose input is the original program sound, and the second one in use employs therespeak methodwhose input is the speech rephrased by arespeakerthe new system employs a hybrid method combining thedirectandrespeakmethods. This paper also describes approaches to improving the accuracy of spontaneous speech recognition in order to enlarge the number of closedcaptioned TV programs. NHK R&D/No.122/2010.7 25
