Content CredentialsA signed record (C2PA) of how the file was made, sealed so any change shows.

Not stated. None of ElevenLabs's pages listed under Sources read says so.

ElevenLabs' safety page says it incorporates third-party standards such as C2PA, but does not say which outputs carry C2PA data.

Invisible watermarkA signal woven into the pixels, frames, audio or wording, meant to survive copying.

ElevenLabs says it embeds an inaudible watermark in the audio its own models generate, at the moment of generation, to make it easier for anyone to verify whether audio came from its platform. It says audio from third-party models available through ElevenLabs is generally not watermarked unless stated otherwise.

ElevenLabs does not name the watermark technology, or say which products or plans it covers or since when.

Audio detector (ElevenLabs Documentation)ElevenLabs

Quoted passage What is watermarking?

Watermarking is a digital technology designed to identify AI-generated content. It embeds imperceptible patterns into audio at frequencies masked by existing sound, making the watermark completely inaudible while maintaining audio quality.

What is the difference between the ElevenLabs AI Speech Classifier and the new Audio Detector tool?ElevenLabs

Quoted passage Answer, paragraphs 2 and 3

The Audio Detector works differently: it scans the audio for a watermark that was cryptographically embedded into it at the time of generation. This makes it significantly more robust and reliable, but because watermarking is new, it can only detect audio generated after watermarking was introduced.

What is watermarking, and why is ElevenLabs using it?ElevenLabs

Quoted passage Answer

Watermarking is a digital technology designed to identify AI-generated content. It embeds imperceptible digital watermarks directly into AI-generated audio. ElevenLabs embeds watermarks into audio we generate to make it easier for anyone to verify whether a piece of audio originated from our platform.

Audio detector (ElevenLabs Documentation)ElevenLabs

Quoted passage Using the audio detector (warning)

The Audio Detector can only detect watermarks embedded by ElevenLabs. It will not detect watermarks from other AI platforms. Additionally, content generated by third-party models available through ElevenLabs is generally not watermarked.

Is content generated by third-party models available through ElevenLabs watermarked?ElevenLabs

Quoted passage Answer

Generally no. Our watermarking is specific to audio content that is generated directly by ElevenLabs. Content generated by third-party models available through the platform is typically not watermarked unless explicitly stated otherwise.

AI label in metadataA plain metadata field (IPTC Digital Source Type) saying AI made the content. Anyone can add or remove it.

Not stated. None of ElevenLabs's pages listed under Sources read says so.

Visible markA mark you can see, such as a logo or a sparkle in a corner.

Not stated. None of ElevenLabs's pages listed under Sources read says so.

Tool named in metadataThe tool or model written into ordinary file fields, such as Software or Creator.

Limits and detection

Checking tool from the makerA way the maker offers to check a file for its traces.

ElevenLabs' Audio Detector, free for signed-in users, checks audio for its watermark and falls back to the AI Speech Classifier when none is found. The classifier is public, needs no login, uses the first minute of a sample and returns the probability that it was made with ElevenLabs voice technology.

Audio detector (ElevenLabs Documentation)ElevenLabs

Quoted passage Overview

Uses watermarking technology to detect imperceptible watermarks embedded in ElevenLabs-generated audio. Free for signed-in users. The tool first checks for a watermark, then falls back to the AI Speech Classifier if no watermark is found.

What the maker says about limitsIn the maker's own words.

ElevenLabs says its Audio Detector detects only watermarks embedded by ElevenLabs, not those of other AI platforms, and that audio from third-party models available through ElevenLabs is generally not watermarked unless stated otherwise.

What the maker says about limitsIn the maker's own words.

ElevenLabs says no other platforms can currently detect its watermarks, and that its watermarking is not connected to other platforms' monetization or content policies.

Audio detector (ElevenLabs Documentation)ElevenLabs

Quoted passage Watermarking details / Platform compatibility

No other platforms can currently detect ElevenLabs watermarks. Watermarking is focused on public AI transparency and is not connected to other platforms’ monetization or content policies.

Will watermarks cause my content to be flagged, downranked, or demonetized on YouTube or other platforms?ElevenLabs

Quoted passage Answer

No other platforms can currently detect ElevenLabs watermarks. Our watermarking is focused on public AI transparency — giving people the ability to verify whether audio is AI-generated — and is not connected to other platforms’ monetization or content policies.

What the maker says about limitsIn the maker's own words.

ElevenLabs says the Audio Detector can only detect audio generated after watermarking was introduced. It does not give that date.

What the maker says about limitsIn the maker's own words.

ElevenLabs describes its AI Speech Classifier as a legacy, statistical tool that may produce false positives or miss modified audio. It works only with content from older ElevenLabs text-to-speech models and does not reliably classify audio from the Eleven v3 model.

Audio detector (ElevenLabs Documentation)ElevenLabs

Quoted passage Difference between audio detector and AI speech classifier

The standalone AI Speech Classifier page remains available separately without requiring sign-in. This legacy tool uses machine learning to analyze audio characteristics and predict whether content was likely generated by ElevenLabs. However, this approach is statistical and may produce false positives or miss modified audio.

What is the difference between the ElevenLabs AI Speech Classifier and the new Audio Detector tool?ElevenLabs

Quoted passage Answer, paragraph 1

The AI Speech Classifier is a legacy tool that uses a trained machine learning classifier to predict whether a given audio clip was generated by ElevenLabs. It only works with content generated by older ElevenLabs TTS models.

Quoted passage Section 10, AI Transparency

You must clearly disclose when people are interacting with AI where required by law or where failing to do so would materially mislead them. You must not remove, alter, or conceal ElevenLabs watermarks, metadata or other provenance signals for the purpose of disguising AI-generated content or evading detection.
