System and method for improving recognition accuracy in speech recognition applications
First Claim
Patent Images
1. A wireless communications system, comprising:
- a controlling computer;
one or more wireless access points connected to the controlling computer by a network;
a badge that communicates using a wireless protocol with one of the wireless access points; and
wherein the controlling computer further comprises a speech recognition system that receives a voice command from a particular user through the badge and interprets the voice command of the user to generate a set of voice commands interpretations, the speech recognition system further comprising an inner circle mechanism having an inner circle store containing a list of entities associated with the particular user, the inner circle mechanism improving the accuracy of the set of voice commands interpretations to generate a best fit voice command corresponding to the received voice command of the user.

Abstract
A speech recognition system and method are provided to correctly distinguish among multiple interpretations of an utterance. This system is particularly useful when the set of possible interpretations is large, changes dynamically, and/or contains items that are not phonetically distinctive. The speech recognition system extends the capabilities of mobile wireless communication devices that are voice operated after their initial activation.

9. A wireless communications system, comprising:
-
a controlling computer;
one or more wireless access points connected to the controlling computer by a network;
a badge that communicates using a wireless protocol with one of the wireless access points; and
wherein the controlling computer further comprises a speech recognition system that receives a voice command from a particular user through the badge and interprets the voice command of the user to generate a set of resulting voice command interpretations, the speech recognition system further comprising a say or spell mechanism that permits the user to spell a voice command, making it sufficiently phonetically distinct from other voice commands allowed in the grammar, in order to reduce the chance of an incorrect voice command interpretation. - View Dependent Claims (10, 11)

12. A method for improving the accuracy of a computer-implemented speech recognition system, the method comprising:
-
obtaining a set of voice command interpretations from a speech recognition engine, each voice command interpretation having a verb portion;
partitioning the set of voice command interpretations into one or more isomorphic sets, each isomorphic set containing one or more voice command interpretations having a common verb portion;
filtering the one or more voice command interpretations in each isomorphic set to generate a preferred voice command interpretation; and
outputting the preferred voice command interpretation. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A method for improving the accuracy of a computer-implemented speech recognition system, the method comprising:
-
receiving a voice command from a user, the voice command having a verb portion and an argument portion;
spelling the verb portion of the voice command to distinguish similar voice command interpretations and generate a set of voice command interpretations; and
spelling the argument portion of the voice command to further distinguish similar voice command interpretations to generate a reduced set of voice command interpretations. - View Dependent Claims (24, 25)

26. A computer implemented speech recognition system, comprising:
-
a speech recognition engine that generates a set of voice command interpretations based on a voice command of a user; and
an inner circle mechanism, connected to the speech recognition engine, the inner circle mechanism having an inner circle store containing a list of entities associated with the user, the inner circle mechanism improving the accuracy of the set of voice commands interpretations to generate a best fit voice command corresponding to the voice command of the user. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33)
