Auto-Generation of Parsing Grammars from a Concept Ontology

摘要

An ontology stores information about a domain of an automatic speech recognition (ASR) application program. The ontology is augmented with information that enables subsequent automatic generation of a speech understanding grammar for use by the ASR application program. The information includes hints about how a human might talk about objects in the domain, such as preludes (phrases that introduce an identification of the object) and postludes (phrases that follow an identification of the object).

主权项

1. A computerized ontology for facilitating automatically generating a speech understanding grammar for an automatic speech recognition (ASR) application program, the ontology comprising:
a computerized database containing information about a plurality of hierarchically organized concepts related to a domain of the ASR application program; and for each of at least a subset of the plurality of concepts, information associated with the concept, wherein the information comprises at least one hint about how a human speaker might refer to the concept in an utterance.
