Abstract
Techniques for audio authentication for digital telephony are disclosed. In an example method, a computing device receives a user voice sample. The computing device determines one or more user voice features from the user voice sample and generates a user voice model based on the one or more user voice features. Next, the computing device receives, from a client device, first authentication information including an authentication voice sample. The computing device again determines one or more authentication voice features from the authentication voice sample and generates an authentication voice model based on the one or more authentication voice features. The computing device then determines a difference between the user voice model and the authentication voice model. In response to the difference being less than a predetermined threshold, the computing device outputs, to the client device, an authentication grant.
