| Abstract(in English) | Text corpus size is an important issue when building a language model (LM). This is a particularly important issue for languages where little data is available. This paper introduces a LM adaptation technique to improve a LM built using a small amount of task dependent text with the help of a machine-translated text corpus. Perplexity experiments were performed using data, machine translated (MT) from English to French on a sentence-by-sentence basis and using dictionary lookup on a word-by-word basis. Then perplexity and word error rate experiments using MT data from English to Icelandic were done on a word-by-word basis. For the latter, the baseline word error rate was 41.4%. LM interpolation reduced word error rate significantly to 37.6%. |
