Outline of Final Research Achievements

First of all, we developed Japanese and English lecture speech recognition systems based on DNN. Next, we studied on English to Japanese translation for lecture speech. We transcribed English lectures by using plural English recognition systems and translated to Japanese based on a statistical machine translation system (SMT). Then, we selected the best translation from plural translation candidates by using a re-scoring technique based on language models and improved the translation result. For attacking mis-recognition errors, we simulated speech recognizers and used them as the training data for the SMT.
By 1-year extension of the research period, we developed a neural machine translation system (NMT), and combine SMT and NMT. By re-scoring based on back translation for these translation candidates, we improved remarkably the translation performance.
Finally, we applied the above techniques to the translation from Japanese lecture speech to English caption.
