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.
Claims20
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;
- and
- 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.
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, 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;
- and
- 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.
A computer-readable storage device having instructions stored which, when executed by a computing device, cause the computing device to perform operations 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;
- and
- 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.
