Deepfake voice detection.

Updated July 2026

Cloned and synthetic voices are convincing enough to fool the ear. Drop a recording in and get a citable verdict, with the generator named, in under half a second.

Deepfake voice detection determines whether spoken audio was generated by a voice-cloning or text-to-speech model rather than a real person. A detector reads the acoustic fingerprint of the clip, the spectral, prosodic, and timing traces synthesis leaves behind, and returns a probability, a confidence level, and the source model where recognized, usually in under half a second.
What it is

A voice deepfake, and why the ear fails

A voice deepfake is speech produced or cloned by a model such as ElevenLabs, Resemble, or PlayHT, often from seconds of sample audio. Current systems reproduce prosody and timbre well enough that listeners perform close to chance on clean clips. The reliable signal is acoustic: synthesis leaves artifacts in the spectrum, in breath and pause placement, and in phoneme transitions that a trained model reads even when a person hears nothing wrong. For the tells you can check by ear first, see AI voice vs human voice.

How detection works

The audio, not the words

The detector analyzes the sound, not the script, so it works across languages and accents and on both cloned and stock voices. It names the generator where the signature is recognizable and returns an honest "unknown synthesis" when it cannot attribute the source. The method is retrained monthly and version-stamped on every verdict. See the full detection methodology.

Not a generic deepfake tool

We are voice and audio only. That is a deliberate scope: most deepfake tools are built for images or video and treat audio as a bolt-on. We name 24+ voice generators and report the evidence behind each verdict. We can read the audio track of a video, but we do not analyze the images, and we never claim a guaranteed 100% result.

Fraud, journalism, and evidence

Fraud teams screen flagged recordings for cloned-voice CEO and vishing attacks; see the fraud detection use case. Newsrooms verify audio before publishing, and investigators keep a citable verdict for a case file. Build it into your own workflow with the API, which returns the same JSON verdict with webhooks. For provenance beyond detection, content-authenticity standards like C2PA attach origin data to genuine media and complement a detector.

To verify a specific clip now, open the detector, or start from a suspected generator on the detect pages.

FAQ · Deepfake voice detection

Common questions

What is deepfake voice detection?
It is determining whether spoken audio was produced by a voice-synthesis or voice-cloning model rather than a real person. A detector reads the acoustic fingerprint of the clip, the spectral and prosodic traces synthesis leaves behind, and returns a probability, a confidence level, and the source model where recognized.
Do you detect deepfake video too?
We are voice and audio only. We can analyze the audio track of a video file, but we do not analyze the images. For a synthetic face or lip-sync, a video-specific tool is needed; we answer whether the voice is real.
How is this different from a generic deepfake detector?
Most generic detectors are tuned for images or video and treat audio as an afterthought. We are specialized for voice: we name 24+ voice generators (ElevenLabs, Resemble, PlayHT, OpenAI, and more) and report the acoustic evidence behind each verdict.
How accurate is it?
About 99% on clean audio. Heavily compressed or very short clips lower confidence, and the detector reports that rather than guessing. No detector should claim a guaranteed 100% result.
Is there a free deepfake voice detector?
Yes. A single verdict is free with no account. Higher volumes and the API begin on the paid plans.
