SYSTEM AND METHOD FOR ENHANCING SPEECH RECOGNITION ACCURACY
First Claim
1. A method comprising:
- identifying, via a processor, segments of a dialog system based on probable user responses;
activating a weighted grammar for a segment of dialog in the dialog system during the segment, to yield an activated weighted grammar; and
recognizing user speech received during the segment of the dialog using the activated weighted grammar.

Abstract
Disclosed herein are systems, computer-implemented methods, and computer-readable media for enhancing speech recognition accuracy. The method includes dividing a system dialog turn into segments based on timing of probable user responses, generating a weighted grammar for each segment, exclusively activating the weighted grammar generated for a current segment of the dialog turn during the current segment of the dialog turn, and recognizing user speech received during the current segment using the activated weighted grammar generated for the current segment. The method can further include assigning probability to the weighted grammar based on historical user responses and activating each weighted grammar is based on the assigned probability. Weighted grammars can be generated based on a user profile. A weighted grammar can be generated for two or more segments. Exclusively activating each weighted grammar can include a transition period blending the previously activated grammar and the grammar to be activated.
