Appeal No. 1999-1581
Application No. 08/651,369
Claim 1 is illustrative of the claimed invention, and it
reads as follows:
1. A method for improving word classification
performance of a speech recognition system allowing
multiple speech attempts from a user, the method
comprising:
storing a predefined vocabulary of word models and
non-word models, the word models containing speech
representations of acceptable words and the non-word
models containing speech representations of non-words;
comparing each of the speech attempts to the word
models and the non-word models to determine a plurality
of best words and corresponding word scores and non-word
scores for each of the speech attempts;
determining at least one common best word from among
all the speech attempts;
determining if the at least one common best word is
a highest-ranking best word based on the corresponding
word scores for all speech attempts by the user;
if so, classifying the multiple speech attempts as
the at least one common best word if the at least one
common best word is the highest-ranking best word for all
the speech attempts; and
if not, performing an objective test on each of the
at least one common best word to classify the multiple
speech attempts.
