Method of accessing a dial-up service
First Claim
Patent Images
1. A method comprising:
- comparing, via a processor, a feature coefficient generated from a speech signal to a user-specific codebook associated with a user who provided the speech signal, to yield a similarity value, wherein the user-specific codebook comprises codes that are formed from cepstrum coefficients generated from utterances spoken by the user;
when the similarity value meets a threshold;
adding the speech signal to a database of reference speech signals; and
adding the feature coefficient to the user-specific codebook; and
performing a speaker verification process of the user based on the database of reference speech signals and the user-specific codebook.

Abstract
A method of accessing a dial-up service is disclosed. An example method of providing access to a service includes receiving a first speech signal from a user to form a first utterance; recognizing the first utterance using speaker independent speaker recognition; requesting the user to enter a personal identification number; and when the personal identification number is valid, receiving a second speech signal to form a second utterance and providing access to the service.

8. A system comprising:
-
a processor; and a computer-readable storage medium having instructions stored which, when executed by the processor, cause the processor to perform operations comprising; comparing a feature coefficient generated from a speech signal to a user-specific codebook associated with a user who provided the speech signal, to yield a similarity value, wherein the user-specific codebook comprises codes that are formed from cepstrum coefficients generated from utterances spoken by the user; when the similarity value meets a threshold; adding the speech signal to a database of reference speech signals; and adding the feature coefficient to the user-specific codebook; and performing a speaker verification process of the user based on the database of reference speech signals and the user-specific codebook. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A non-transitory computer-readable storage device having instructions stored which, when executed by a computing device, cause the computing device to perform operations comprising:
-
comparing a feature coefficient generated from a speech signal to a user-specific codebook associated with a user who provided the speech signal, to yield a similarity value, wherein the user-specific codebook comprises codes that are formed from cepstrum coefficients generated from utterances spoken by the user; when the similarity value meets a threshold; adding the speech signal to a database of reference speech signals; and adding the feature coefficient to the user-specific codebook; and performing a speaker verification process of the user based on the database of reference speech signals and the user-specific codebook. - View Dependent Claims (16, 17, 18)
