Appeal No. 1999-2294
Application No. 08/807,430
BACKGROUND
Appellants’ invention relates to a speech recognition system using nonparametric
speech models. An understanding of the invention can be derived from a reading of
exemplary claim 19, which is reproduced below.
19. A speech recognition system comprising:
an input device configured to receive a speech sample to be recognized;
a stored nonparametric vocabulary representing utterances from one or more
human speakers, the vocabulary including discrete training observations, each of which
represents a single utterance by a single speaker; and
a processor coupled to the input device and to the nonparametric vocabulary and
configured to evaluate the speech sample against the nonparametric vocabulary.
The prior art references of record relied upon by the examiner in rejecting the
appealed claims are:
Rabiner et al., A TWO-PASS PATTERN-RECOGNITION APPROACH TO ISOLATED
WORD RECOGNITION, The Bell System Technical Journal (Journal), May-June 1981, Vol.
60, No. 5, pp. 739-766.
Scott, David W., MULTIVARIATE DENSITY ESTIMATION THEORY, PRACTICE, AND
VISUALIZATION, (John Wiley & Sons, Inc. 1992), pp. 19, 154-157.1
1We note that the examiner indicated in the references relied upon section of the answer that the
Scott reference was the Proceedings of the 6th Annual Conf. and Expo: Computer Graphics, Vol. III, pp.
715-718, but the rejection cites to various pages and sections only found in the Scott book above.
Therefore, we understand the rejection to be based on the book rather than the article. Appellants
concurred in this understanding at the hearing.
