Embodiments of the invention are directed to systems and methods for speech transaction processing. A location of a device associated with a user may be determined. A reference to a voice model associated with the user stored within a database may be retrieved, based at least in part on the location. A voice segment may be received from the user. Using the reference, the voice segment may be compared to the voice model stored within the database. A determination may be made whether the user is authenticated for the transaction based on the comparing step.
