Authenticate audio evidence.

Recordings enter evidence already suspect

Cloned-voice clips now surface in disputes, custody matters, employment cases, and fraud investigations, where a fabricated recording can shift a decision before anyone questions it. Investigators and counsel need a defensible way to ask whether a recording is synthetic, with a record of how the question was answered.

A citable, reproducible analysis

Run the recording through the detector and save the verdict. You get a probability, a confidence level, the recognized model, a methodology version stamp, and a one-way audio fingerprint, all under a permanent citation URL. Because the methodology is published and versioned, an opposing expert can reproduce the test against the same snapshot. This is audio authentication in the practical sense: a documented, repeatable analysis of whether the voice was machine-generated. For the method, see how to verify AI audio.

Analysis, not a ruling

We provide a probability with a published method behind it. We do not determine admissibility, we are not a law firm, and we do not certify identity; whether and how a verdict is used in a proceeding is for counsel and the court. We analyze recordings after the fact, delete audio within 24 hours unless a verdict is saved, and never claim a guaranteed 100% result. Integrate into a review workflow with the API, and for provenance see C2PA. The goal is narrow and defensible: a documented answer to whether the voice was machine-generated, produced the same way every time, that an expert on either side can examine.

Where confidence comes from

The verdict is a probability, never rounded up, paired with a confidence level driven by the length and quality of the recording. Clean, longer audio yields high confidence; short, compressed, or noisy clips yield less, and the detector reports that honestly rather than overstating certainty. For a contested recording, capture the clearest available copy and avoid re-recording it through another device, which adds compression and strips the artifacts the analysis relies on. Because the analysis is documented and repeatable, it supports a case file, a dispute, or a referral without asking anyone to trust a black box.
