How it works.

  1. Capture the voice

    Receive a suitable speech segment from the call.

  2. Create a representation

    Convert the segment for speaker comparison.

  3. Compare

    Evaluate it against the enrolled reference under a defined threshold.

  4. Return the state

    Send the result to accept, review, or escalate.

Identity is one signal in the call, checked alongside authenticity.

Check both speech authenticity and the enrolled speaker before advancing a sensitive request.

Plan the deployment.

A speaker comparison is one identity signal and should be combined with the controls appropriate to the transaction risk.
