Abstract(in English) | Recent large vocabulary speech recognition systems consist of two statistical models, the acoustic and language models. In acoustic modeling, deep neural networks have realized a breakthrough and significant performance improvements have been achieved. On the other hand, in language modeling, there have not been any reports of comparable improvements. Although it is clear that recent practical language models have several problems such as "locality", "task dependency" and "data sparseness", we cannot obtain significant performance improvements by solving these problems separately. In this paper, we try to use various language modeling techniques simultaneously to cover the entire problem. Our investigation is conducted by dividing language modeling techniques into three viewpoints, "one pass decoding", "unsupervised adaptation" and "rescoring". |
