| dc.description.abstract | V tomto článku zkoumáme adaptaci jazykových modelů na konkrétního řečníka v úloze automatické segmentace do dialogových aktů. Adaptace je provedena jako lineární interpolace obecného modelu s modelem natrénovaným jenom na datech konkrétního řečníka. Metoda byla testována na 20 nejčastějších řečnících v databázi záznamu mítinků. bylo dosaženo zlepšení pro 17 resp. 15 řečníků pro ruční resp. automatické přepisy. | cs |
| dc.description.abstract-translated | Dialog act (DA) segmentation in meeting speech is important for meeting understanding. In this paper, we explore speaker adaptation of hidden event language models (LMs) for DA segmentation using the ICSI Meeting Corpus. Speaker adaptation is performed using a linear combination of the generic speakerindependent LM and an LM trained on only the data from individual speakers. We test the method on 20 frequent speakers, on both reference word transcripts and the output of automatic speech recognition. Results indicate improvements for 17 speakers on reference transcripts, and for 15 speakers on automatic transcripts. Overall, the speaker-adapted LM yields statistically significant improvement over the baseline LM for both test conditions. | en |
