1. A system for providing an acoustic grammar to dynamically sharpen speech interpretation, wherein the system comprises an electronic device configured to: represent one or more syllables with one or more series that include acoustic elements associated with an acoustic speech model; and construct an acoustic grammar that contains transitions between the acoustic elements in the one or more series associated with the one or more represented syllables, wherein an unstressed central vowel links sequential phonemic elements in the acoustic grammar to reduce the transitions between the acoustic elements.
