15. A grammar rule generator for use in a speech recognition system, said speech recognition system converting an audible signal representative of spoken words to a textual output from, said speech recognition system comprising a natural language processor for parsing a partially recognized sentence, said grammar rule generator, and a speech recognition engine, said grammar rule generator being configured to generate a dynamic grammar rule from the partially recognized sentence and provide the dynamic grammar rule to the speech recognition engine by: utilizing the natural language processor to parse the partially recognized speech into a pre-determined sentence type and an ordered list of recognized words and place holders corresponding to unrecognized sound groups; selecting a list of grammar rules associated with the pre-determined sentence type from a plurality of grammar rules stored by a storage unit on a storage medium, each grammar rule in said list having a plurality of constituent concepts, each of said constituent concepts corresponding to one of the recognized words and the unrecognized sound groups by position in said order list; for each place holder corresponding to said unrecognized sound group, merging said corresponding constituent concepts in all said selected grammar rules into a list of concepts; generating the dynamic grammar rule from said ordered list by replacing each concept in said list of merged concepts with a list of keywords a list of candidate words using pre-determined concept to keywords mappings stored by the storage unit wherein each of the keywords mapped from the merged concept are expandable to a plurality of words conceptually related to each of the merged concepts and wherein the plurality of words are the list of candidate words; and providing the dynamic grammar rule to the speech recognition engine to enable the speech recognition engine to use the dynamic grammar rule to resolve the unrecognized sound groups in the partially recognized speech corresponding to the place holders and to convert the audible signal to the textual output.
15. A grammar rule generator for use in a speech recognition system, said speech recognition system converting an audible signal representative of spoken words to a textual output from, said speech recognition system comprising a natural language processor for parsing a partially recognized sentence, said grammar rule generator, and a speech recognition engine, said grammar rule generator being configured to generate a dynamic grammar rule from the partially recognized sentence and provide the dynamic grammar rule to the speech recognition engine by: utilizing the natural language processor to parse the partially recognized speech into a pre-determined sentence type and an ordered list of recognized words and place holders corresponding to unrecognized sound groups; selecting a list of grammar rules associated with the pre-determined sentence type from a plurality of grammar rules stored by a storage unit on a storage medium, each grammar rule in said list having a plurality of constituent concepts, each of said constituent concepts corresponding to one of the recognized words and the unrecognized sound groups by position in said order list; for each place holder corresponding to said unrecognized sound group, merging said corresponding constituent concepts in all said selected grammar rules into a list of concepts; generating the dynamic grammar rule from said ordered list by replacing each concept in said list of merged concepts with a list of keywords a list of candidate words using pre-determined concept to keywords mappings stored by the storage unit wherein each of the keywords mapped from the merged concept are expandable to a plurality of words conceptually related to each of the merged concepts and wherein the plurality of words are the list of candidate words; and providing the dynamic grammar rule to the speech recognition engine to enable the speech recognition engine to use the dynamic grammar rule to resolve the unrecognized sound groups in the partially recognized speech corresponding to the place holders and to convert the audible signal to the textual output. 16. The grammar rule generator of claim 15 , the grammar rule generator being further configured to assign a context designation to said dynamic grammar rule.
