SYSTEM AND METHOD FOR PROVIDING AN ACOUSTIC GRAMMAR TO DYNAMICALLY SHARPEN SPEECH INTERPRETATION
First Claim
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.

Abstract
The system and method described herein may provide an acoustic grammar to dynamically sharpen speech interpretation. In particular, the acoustic grammar may be used to map one or more phonemes identified in a user verbalization to one or more syllables or words, wherein the acoustic grammar may have one or more linking elements to reduce a search space associated with mapping the phonemes to the syllables or words. As such, the acoustic grammar may be used to generate one or more preliminary interpretations associated with the verbalization, wherein one or more post-processing techniques may then be used to sharpen accuracy associated with the preliminary interpretations. For example, a heuristic model may assign weights to the preliminary interpretations based on context, user profiles, or other knowledge and a probable interpretation may be identified based on confidence scores associated with one or more candidate interpretations generated with the heuristic model.

13. A computer-readable storage medium that stores an acoustic grammar, wherein the acoustic grammar stored on the computer-readable storage medium comprises:
-
one or more syllable representations, wherein the one or more syllable representations arrange acoustic elements associated with an acoustic speech model in one or more series; and transitions between the acoustic elements associated with the one or more syllable representations, wherein an unstressed central vowel links sequential phonemic elements associated with the one or more syllable representations to reduce the transitions between the acoustic elements. - View Dependent Claims (14, 15, 16, 17, 18)
