System and method of word lattice augmentation using a pre/post vocalic consonant distinction
First Claim
1. The method for recognizing speech, the method comprising:
- receiving, via a processor, an input speech having at least one pre-vocalic consonant or at least one post-vocalic consonant;
generating at least one output lattice that calculates a first score by comparing the input speech to a training model to provide a result;
distinguishing between the at least one pre-vocalic consonant and the at least one post-vocalic consonant in the input speech;
calculating a second score by measuring a similarity between the at least one pre-vocalic consonant or the at least one post-vocalic consonant in the input speech and the first score;
determining at least one category for at least one pre-vocalic match or mismatch or at least one post-vocalic match or mismatch by using the second score; and
refining the results of the an automated speech recognition system by using the at least one category for at least one pre-vocalic match or mismatch or at least one post-vocalic match or mismatch.

Abstract
Systems and methods are provided for recognizing speech in a spoken dialogue system. The method includes receiving input speech having a pre-vocalic consonant or a post-vocalic consonant, generating at least one output lattice that calculates a first score by comparing the input speech to a training model to provide a result and distinguishing between the pre-vocalic consonant and the post-vocalic consonant in the input speech. A second score is calculated by measuring a similarity between the pre-vocalic consonant or the post vocalic consonant in the input speech and the first score. At least one category is determined for the pre-vocalic match or mismatch or the post-vocalic match or mismatch by using the second score and the results of the an automated speech recognition (ASR) system are refined by using the at least one category for the pre-vocalic match or mismatch or the post-vocalic match or mismatch.

8. A system for recognizing speech, the system comprising:
-
a first module configured, via a processor, to receive an input speech having at least one pre-vocalic consonant or at least one post-vocalic consonant; a second module configured to generate at least one output lattice that calculates a first score by comparing the input speech to a training model to provide a result; a third module configured to distinguish between the at least one pre-vocalic consonant and the at least one post-vocalic consonant in the input speech; a fourth module configured to calculate a second score by measuring a similarity between the at least one pre-vocalic consonant or the at least one post vocalic consonant in the input speech and the first score; a fifth module configured to determine at least one category for at least one pre-vocalic match or mismatch or at least one post-vocalic match or mismatch by using the second score; and a sixth module configured to refine the results of the an automated speech recognition system by using the at least one category for at least one pre-vocalic match or mismatch or at least one post-vocalic match or mismatch. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A non-transitory computer-readable medium storing instructions for controlling a computing device to process speech, the instructions comprising:
-
receiving, via a processor, an input speech having at least one pre-vocalic consonant or at least one post-vocalic consonant; generating at least one output lattice that calculates a first score by comparing the input speech to a training model to provide a result; distinguishing between the at least one pre-vocalic consonant and the at least one post-vocalic consonant in the input speech; calculating a second score by measuring a similarity between the at least one pre-vocalic consonant or the at least one post-vocalic consonant in the input speech and the first score; determining at least one category for at least one pre-vocalic match or mismatch or at least one post-vocalic match or mismatch by using the second score; and refining the results of the an automated speech recognition system by using the at least one category for at least one pre-vocalic match or mismatch or at least one post-vocalic match or mismatch. - View Dependent Claims (16, 17, 18, 19, 20, 21)
