Appeal No. 2002-1982
Application No. 08/863,462
in Figure 6 and described in page 12 of the specification, a user
dials a service number and is prompted to speak a plurality of
digits. Using speaker independent voice recognition of step 176,
the uttered digits are compared to a stored utterance. Access is
allowed if the user is verified otherwise; the user is prompted
to input a personal identification number (PIN) which provides
access upon verification.
Representative independent claims 1 and 10 are reproduced
below:
1. A method of accessing a dial-up service,
comprising the steps of:
(a) dialing a service number;
(b) speaking a plurality of digits to form a first
utterance;
(c) recognizing the plurality of digits using speaker
independent speaker recognition;
(d) when a user has used the dial-up service
previously, verifying the user based on the first utterance
using a speaker verification system that has only two
possible decisions verified and not verified;
(e) when the user is not verified, requesting the
user to enter a personal identification number; and
(f) when the personal identification number is valid,
providing access to the dial-up service.
