Authenticity Verification

Authenticity verifications analyze the authenticity and liveliness of an audio to validate that the voice belongs to a human speaking live.

They can be used to detect a variety of spoofing or spam attempts, including the use of synthetic voices.

Combining authenticity verifications with message verifications can improve robustness against spoofing attempts.

Access: To manage a verification, you must have access to its space.

Isolation: A verification can only interact with resources inside its space.

Model: The analysis of the authenticity and liveliness of the voice is powered by a specific version of an authenticity verification model.

Scores: Confidence in positive results in different metrics is represented in the scores field.
