Whereas topic-based adaptation of language models (LM) claims to increase the accuracy of topic-specific words within automatic speech recognition, this paper investigates why this wish is not always verified.

In addition to a better accuracy on topic-specific words, results show better graph error rates and word error rates on a set of spoken documents with various topics
