Voice Authentication System and Method |
| 摘要 |
A method for maintaining a voiceprint utilisable to authenticate a user comprises associating a trainable universal background model with the user. A voiceprint for the user is generated utilising the trainable universal background model and at least one enrolment voice sample provided by the user. The trainable universal background model is subsequently trained with additional voice samples provided by the user post enrolment that satisfy predefined adaptation criteria. The voiceprint is regenerated responsive to a change to the trainable universal background model. |
