Abstract :
The integration of an LR natural language parser with the SPHINX speech recognition system is described. LR parsing was incorporated into SPHINX to provide more global grammatical constraints. However, when using a tight grammar in a left-to-right continuous speech recognizer, when one word is missing or wrong, often several subsequent words are also incorrect. A solution to this problem that involves combining a context-free grammar with a bigram grammar is proposed
