SYSTEM HAVING COMPOSITE STATISTICS MODEL AND RULE-BASED GRAMMAR MODEL FOR SPEECH RECOGNITION AND NATURAL LANGUAGE UNDERSTANDING

摘要

PURPOSE: A system having a composite statistics and rule based grammar model is provided to perform both of speech recognition operation and natural language understanding using a composite statistics model and a rule-based grammar language model. CONSTITUTION: A model authoring system(200) includes a model authoring component(202) and an optional user interface(204). The model authoring component receives schema(206), a training illustration text string(208), and an optional grammar library(209) as inputs and outputs a rule-based grammar(210). The optional grammar library includes a definition for an area-dependent concept obtained from an application database and an area-independent concept. A user provides the schema and the training illustration text string to the model authoring component through the optional user interface.
