摘要:A new real-time closed-captioning system for Japanese TV news broadcasts is described. The system is based on a hybrid automatic speech recognition system that switches its speech input between the original program sound and speech rephrased by a “re-speaker”. By improving our speech recognizer and its error correction system, we decreased the number of correction operators needed from four in our previous news system to one or two, depending on the difficulty of the speech recognition. Experimental results show that the system could be used at broadcasting stations for captioning typical news programs more easily and by fewer staff.
