ABSTRACT:
The method and system for modifications of grammars presented in this invention applies to automatic speech recognition systems which take a spoken utterance as input and use a grammar to assign word sequence(s) and, possibly, one or more semantic interpretations to that utterance. One type of modification may take a form of reducing the importance of select grammar components based on the analysis of the occurrence of these components in the original grammar. Another type of modification may take form of adding new grammar components to the grammar of some semantic interpretations based on the analysis of the occurrence of these components in the select set of other semantic interpretations. Both modifications can be carried out either automatically or offered for validation. Some benefits of the presented method and system are: reduced effort for building grammars, improvement of recognition accuracy, automatic adaptation of dynamic grammars to the context.
