Patent number: 8386263Abstract: In one aspect, a method for determining a validity of an identity asserted by a speaker using a voice print is provided. The method comprises acts of performing a first verification stage comprising comparing a first voice signal from the speaker uttering at least one first challenge utterance with at least a portion of the voice print and performing a second verification stage if it is concluded in the first verification stage that the first voice signal was obtained from an utterance by the user.

Publication number: 20100106503Abstract: In one aspect, a method for determining a validity of an identity asserted by a speaker using a voice print that models speech of a user whose identity the speaker is asserting is provided. The method comprises acts of performing a first verification stage comprising acts of obtaining a first voice signal from the speaker uttering at least one first challenge utterance; and comparing at least one characteristic feature of the first voice signal with at least a portion of the voice print to assess whether the at least one characteristic feature of the first voice signal is similar enough to the at least a portion of the voice print to conclude that the first voice signal was obtained from an utterance by the user.Type: ApplicationFiled: October 24, 2008Publication date: April 29, 2010Applicant: Nuance Communications, Inc.Inventors: Kevin R.

Patent number: 6820090Abstract: In a method for acquiring statistical information from data, an initial cumulative distribution function (CDF) that characterizes an initial set of data is acquired. The acquisition of this CDF comprises acquiring a set of quantile endpoints that define the CDF. At least one additional CDF, which characterizes a further set of data, is also acquired. Information that describes the initial CDF is combined with information that describes one or more additional CDFs, and the result is used to obtain a composite CDF that describes a combined set of data that includes the initial data set and the one or more further data sets. Then, a new set of quantile endpoints is determined, that defines the composite CDF. The sequence of steps described above is repeated at least once more. The previously obtained composite CDF is used as the initial CDF for each repetition of this sequence.Type: GrantFiled: March 22, 2002Date of Patent: November 16, 2004Assignee: Lucent Technologies Inc.Inventors: John M Chambers, David A James, Diane Lambert, Scott Alan Vander Wiel
