Abstract
A user's voice is authenticated by prompting a user to say a challenge phrase from a list of predetermined phrases and comparing the user's response with a prerecorded version of the same response. The user's stored recordings are associated with an electronic identification or serial number for a specific device, so that when communication is established using the device, only the specific user may authenticate the session. When several phrases and recordings are used, one may be selected at random for authentication so that fraudulent authentication using a recording of the user's voice may be thwarted. The system and method may be used for authenticating a device when it is first activated, such as a telephony device, or may be used when authenticating a specific communications session.
