The invention involves the loading and unloading of dynamic section grammars and language models in a speech recognition system. The values of the sections of the structured document are either determined in advance from a collection of documents of the same domain, document type, and speaker; or collected incrementally from documents of the same domain, document type, and speaker; or added incrementally to an already existing set of values. Speech recognition in the context of the given field is constrained to the contents of these dynamic values. If speech recognition fails or produces a poor match within this grammar or section language model, speech recognition against a larger, more general vocabulary that is not constrained to the given section is performed.
A method for use with an automatic speech recognition system, the method comprising acts of:
At least one computer-readable medium having instructions encoded thereon which, when executed in a system comprising at least one automatic speech recognition component, perform a method comprising acts of:
A system for use with at least one automatic speech recognition component, the system comprising at least one processor programmed to:
