| Abstract(in English) | Telecommunication Advancement Organization of Japan proceeds "Research Project for TV Production for the Seeing and Hearing Impaired" from 1995 to 2001. The purpose of the project is to establish the technologies of producing closed captions for hearing impaired people on TV programs efficiently. We have three research issues in the project: automatic text summarization, automatic synchronization with speech and captions and system engineering. Automatic text summarization summarized Japanese new text to 70% volume. Important sentence extraction, morphem-based text shortening and bunsetsu-based text shortening are used. Automatic synchronization uses HMM-based word spotter and DP-based synchronizing point search. The method can be applicable to new ans narration programs in which signal strength ratio between speech and background sound is more than 20dB. System engineering research results automatic changing method of new page and new line at a point easy to read. We integrate these elementary technologies to the automatic captioning system and evaluate it by caption creators and end users. From this evaluation experiments, we can know the system performance and future research issues. |
