| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | By using Automatic Speech Recognition (ASR) technology, it is possible to subtitle lecture and other voices at low cost and in real time, which is a great help for the hearing impaired people. However, when using the ASR system, there is a problem that the recognition accuracy is greatly influenced by the fact that the technical term tends to become an unknown word especially in a university lecture and the recognition accuracy is greatly influenced by the speaker and the recording environment. In order to correct such a misrecognition result, conventional semi-automatic captioning systems require several operators for simultaneous editing, or cause a large delay for time-consuming editing work. In this paper, we propose a low cost correction method to feedback only a part of errors such as misrecognized technical terms and to identify and correct erroneously recognized segments by using Spoken Term Detection (STD) and lattice modification methods. We also adopt an unsupervised language model adaptation for additional subtitle correction after the modified online caption text were obtained for a lecture. We report the experimental result of our proposed system using the lecture speech corpus. | |
