A review of Hunt reveals that the reference describes a
system and method for enabling a caller to obtain access to
services via a telephone network (abstract). After a first
utterance is stored in the voice verification reference database
(col. 6, lines 2-14), the system performs the step of voice
verification to determine if the utterance is spoken by a voice
previously enrolled (col. 6, lines 20-24). Hunt further
discloses that if a “match” is established, access to the service
is allowed, but the call is terminated if voice cannot be
substantially matched (col. 6, lines 27-30). However, Hunt
provides for another option which prompts the caller to input
additional personal information if the entered voice
substantially matches a stored voice, but not within a
predetermined criterion (col. 6, lines 30-37). It is after the
caller fails to provide such information that the call is
terminated (col. 6, lines 37-39).
