Abstract
A device includes a processor configured to extract parameters from an audio signal. The processor is configured to perform liveness verification by determining, based on first parameters and a liveness data model, whether the audio signal corresponds to a first audio type indicating spoken speech, to perform user verification by determining, based on second parameters and a user speech model, whether the audio signal corresponds to speech of a particular user, and to perform keyword verification by determining, based on third parameters and a keyword data model, whether the audio signal corresponds to a particular keyword. The processor is configured to generate an output indicating that user authentication is successful in response to determining that the audio signal corresponds to speech of the particular user, to the particular keyword, and to the first audio type.
