Biometrics Voice Liveness assesses voice samples for liveness detection and anti-spoofing. You add it to your Trust Flow and configure it in the product Settings panel.

​
How it works

​
Processes

The flow is built around one process:
  • Voice Liveness Check — Evaluates whether the submitted audio comes from a live speaker and applies anti-spoofing checks to reduce replay, synthesis, and other attacks.
This appears as the selectable process when you configure Biometrics Voice Liveness.

​
Inputs

The capture you collect from the end user is:
  • Voice File — The audio sample your flow records or uploads for analysis.
Use a clear recording in a quiet environment when possible so the liveness model can score the sample reliably.

​
Tool settings

Open the Tool settings section in the product settings modal when you need to tune behaviour for Biometrics Voice Liveness. Available controls depend on what is enabled for your account; use the information icons beside each option for explanations.
The options available to you reflect what is enabled for your account—so you may not see every option, and labels can differ slightly. If anything is missing or you need guidance, contact IDmeta support.
