Impact of dynamic model adaptation beyond speech recognition
Fernando Batista, Rui Amaral, Isabel M. Trancoso, Nuno Mamede · 2008
The application of speech recognition to live subtitling of Broadcast News has motivated the adaptation of the lexical and language models of the recognizer on a daily basis with text material retrieved from online newspapers. This paper studies the impact of this adaptation on two of the blocks following the speech recognition module: capitalization and topic indexation. We describe and evaluate different adaptation approaches that try to explore the language dynamics.
