Error Detection and Error Recovery from Speech Recognition: Language Engineering Strategies

María Teresa López-Soto, José F. Quesada

University of Seville, Spain

This work presents a series of strategies developed for a Natural Language Processing (NLP) module, which receives as input a sequence of words generated by a speech recognizer. These strategies have proved to be very effective in detecting and correcting the errors generated at the speech recognition stage. These strategies can be classified into three blocks: lexicomorphological and grammatical flexibility, metrics. The model has been implemented into a real system (automatic telephone operator system); the results generated for this paper have been taken after parsing a Spanish corpus of 1,719 requests to the operator.
