What is the AI Speech Classifier?

The AI Speech Classifier is a free tool that estimates the probability that an audio sample was generated with ElevenLabs AI voice technology. Upload a clip and we return a match score in seconds.

How accurate is the AI Speech Classifier?

It reliably identifies audio generated with most ElevenLabs models. It does not reliably classify audio generated with the Eleven v3 model, and it cannot detect audio from other providers.

Which files and lengths are supported?

You can upload common audio and video files. We analyze the first minute of each sample, and no login is required.

Does it detect audio from other AI voice tools?

No. The classifier is built to detect speech generated with ElevenLabs. It is not a general-purpose detector for every AI voice provider.

What happens to the audio I upload?

We process your sample only to return a result. See our privacy policy for details on how we handle uploaded data.

What should I do if I find concerning AI-generated content?

If you come across content that raises concerns, report it to us so our team can review it and take appropriate action.

Our Safety Principles

We build safety into everything we do—from the ground up. Our models undergo rigorous evaluations before release, and we embed safeguards directly into our products to stop and deter abuse.

Responsible use is non-negotiable. Our systems are designed to trace generated content back to the user who generated it, allowing us to detect and respond to abuse—while preserving the privacy of users who act in good faith.

People should know when they’re interacting with AI. We’re committed to helping our users and the public understand the provenance of the content they consume.

AI risks evolve quickly—so do we. Our cross-functional safety team – including technical, operational, and policy experts – rapidly designs and deploys mitigations that keep pace with emerging threats.

Keeping society safe from AI misuse requires an ecosystem-level approach. We partner up with others to tackle some of the hardest problems in AI safety.
