Voice dialing using a rejection reference
First Claim
Patent Images
1. A voice dialing method, comprising the steps of:
- (a) receiving a first utterance followed by a subsequent utterance from a user via a microphone associated with an automatic speech recognition system;
(b) determining a first recognition result for the first utterance and a subsequent recognition result for the subsequent utterance using a processor associated with the automatic speech recognition system;
(c) communicating the recognition results to the user via an output device associated with the automatic speech recognition system;
(d) receiving from the user a first indication that at least one of the recognition results is incorrect;
(e) populating a rejection reference in memory associated with the automatic speech recognition system with the subsequent recognition result after receiving the first indication;
(f) receiving from the user a second indication that at least one of the recognition results is incorrect after receiving the first indication;
(g) clearing the subsequent recognition result from the rejection reference and populating the rejection reference with the first recognition result after receiving the second indication;
(h) receiving a correction utterance from the user; and
then(i) processing the correction utterance based on the first recognition result being in the rejection reference.

Abstract
A voice dialing method includes the steps of receiving an utterance from a user, decoding the utterance to identify a recognition result for the utterance, and communicating to the user the recognition result. If an indication is received from the user that the communicated recognition result is incorrect, then it is added to a rejection reference. Then, when the user repeats the misunderstood utterance, the rejection reference can be used to eliminate the incorrect recognition result as a potential subsequent recognition result. The method can be used for single or multiple digits or digit strings.
