ElevenLabs, read against Article 50
ElevenLabs documents an inaudible watermark written into generated audio and a detector that reads it. Both statements come from the same documentation page, and the page is candid about where the coverage stops. As of 2026-09-12.
Fig. 1 A single account can produce marked and unmarked audio, and the difference is not visible in the delivered file.Fig. 2 Filled where the page behind the row names something in that column, hollow where that page is silent. Silence is recorded rather than filled in.
What ElevenLabs publishes, set against the two duties Article 50 imposes. Recorded 2026-09-12.
Point
What the vendor's pages state
Article 50(2), machine-readable marking
An inaudible pattern embedded in generated audio
Article 50(4), deployer disclosure
Not addressed; nothing audible or visible is described
Marks this vendor wrote; other platforms are not covered
Inclusion rule. Points are the same four for every generator recorded here: the two Article 50 duties, who controls the mark, and whatever the vendor states about it. A point the vendor does not publish is recorded as not documented. Order. Fixed order, identical on every generator page.

Inclusion rule. Generators whose own public pages say something about marking. A generator silent on this particular point keeps its row, marked hollow. Order. Alphabetical by generator name.

2Audio is inside the paragraph and usually outside the conversation
The marking duty names synthetic audio in the same breath as image, video and text, and almost every discussion of it is about pictures. A cloned voice in a drama, a synthetic narrator on a news explainer and a generated jingle in an advertisement are all inside the wording, and none of them can carry a visible mark at all.
That makes this entry structurally different from the ones read off video plan tables. There is no viewer-facing layer to describe, so the disclosure row records that nothing is addressed rather than recording a mark. Whatever a listener is told about the audio has to be told alongside it, by whoever publishes it, which is where the deployer half of the article lands.
The page states that the detector finds only watermarks this vendor embedded and will not find those written by other platforms. Stated plainly on a product page, that is a useful admission and it is also the shape of the interoperability problem the marking paragraph describes: a mark whose reader is the party who wrote it does not help anyone else decide what they are listening to.
The same page narrows the coverage a second time, from the inside:
content generated by third-party models available through ElevenLabs is generally not watermarked unless explicitly stated otherwise
So a single account can produce marked and unmarked audio depending on which model ran, and the distinction is not visible in the delivered file. A record organised by clause has to keep that: the marking row describes a mark that exists for some output of one product, which is a narrower fact than the row would suggest without this sentence.
Four words is all a row holds. Where a cell read off ElevenLabs's documentation needs the sentence behind it, the kind of document that sentence sits in and the limit on what it proves, it is filed on its own page below.
ElevenLabs on marking audio — Imperceptible patterns are embedded at frequencies masked by sound already present.
ElevenLabs on what its detector finds — The documentation says the detector finds only watermarks this vendor embedded and will not find those of other platforms.
ElevenLabs on models it did not train — The documentation states that models from other providers offered through the platform are generally not watermarked unless stated otherwise.
