| Abstract(in English) | Automatic speech recognition (ASR) of lectures on elementary and secondary education is addressed. Most of conventional studies of lecture speech recognition target on lectures in universities or oral presentations in technical conferences, in which lecturers make their speech for adult audiences. On the contrary, in elementary school or junior high-school, lecture audience is immature people. Lecturers (teachers) often make utterances in a different way from talks to adult audiences. Specifically, teachers try to select easy words and phrases, some of which are only for kids. For ASR of elementary school lectures, a language model which covers such linguistic phenomena is required. In this paper, suitable vocabulary and language model for elementary school lectures are discussed. Word 3-gram language model trained with texts for adults (Corpus of spontaneous Japanese and one-year newspaper articles) cannot cover a half of 3-grams (about 3000 kinds) appeared in 13 lectures in school. We got higher adjusted testset perplexity about 343. Word 3-gram language model trained with small texts for kids (1.2M words from kids-oriented web sites), we can cover one-third of 3-grams, which are not modeled in the language model for adult. We confirmed that it is significant to collect text corpora for ASR of elementary school lectures. |
