Abstract

This paper describes an adaptive language model for recognition tasks, where person names are specific for each recognition session and have to be added to the recognition vocabulary. Creation of an adaptive language model with word (name) classes is illustrated on two different tasks of automatic online subtitling: subtitling of parliament meetings (1.5 % of names) and ice-hockey matches (15 % of names). The second part outlines the system for automatic online subtitling with vocabulary up to 100 000 words in real-time. The recognition system is based on Hidden Markov Models, lexical trees and bigram language model. Finally, experimental results with and without the adaptive language model are reported and discussed.
