Abstract :
In this paper we propose a new approach to integrating a parser into a statistical speech recognizer. The method is able to incrementally apply grammatical restrictions and robustly combine them with the statistical acoustic and language models. On spontaneous speech data a 11.6% reduction in word error rate could be achieved compared to the baseline system applying statistical models only.
