1. A system for performing a task for or providing a service to a source, the system comprising: a first device having a first sensor for receiving recognition information from the source and transmitting the received recognition information to a second device; the first and second devices for independently processing at least different portions of the recognition information, wherein the first and second devices use a common recognition model or use a different recognition model to process the recognition information, and the first and second devices independently assigning a respective first and second recognition score to the source, wherein the second device is communicatively linked to the first device, a dynamic paring code derived from each of the independently assigned recognition scores; one or both of the first and second devices authenticating the source responsive to the first and second recognition scores by collaboratively determining whether the source is authenticated based on the dynamic paring code; and responsive to the source having been authenticated, the first or second device for performing the task or for providing the service to the source.

The system of claim 1 wherein the recognition information comprises sound samples, speech samples, sound features, speech features, voice, whistles, clicks, claps, music, behavior metrics, or biometrics.
