RECOGNITION USING RE-RECOGNITION AND STATISTICAL CLASSIFICATION

摘要

Architecture that employs an overall grammar asa set of context-specific grammars for recognition of an input,each responsible for a specific context, such as subtask category,geographic region, etc. The grammars together cover the entiredomain. Moreover, multiple recognitions can be run in parallelagainst the same input, where each recognition uses one or moreof the context-specific grammars. The multiple intermediaterecognition results from the different recognizer-grammars arereconciled by running re-recognition using a dynamically com-posedgrammar based on the multiple recognition results and po-tentiallyother domain knowledge, or selecting the winner usinga statistical classifier operating on classification features extract-edfrom the multiple recognition results and other domainknowledge.
