ElevenLabs SynthID Audio Watermarking

Properties

kind: provider-policy
target: voice
jurisdiction: ElevenLabs (industry)
mechanism: Embeds an inaudible SynthID digital watermark, built with Google DeepMind, directly into ElevenLabs-generated audio. Paired with a free public ElevenLabs Audio Detector tool so a third party can check whether a given clip was generated by ElevenLabs.
status: in-effect
owns: Distinct from elevenlabs-voice-clone-policy, which gates who may create a clone in the first place (self-ownership plus verification). This policy instead addresses post-hoc detection and provenance of audio that has already been generated, letting any listener verify a clip's AI origin after the fact.
source: ElevenLabs Blog, "Detecting audio generated by ElevenLabs with SynthID"
notes: Blog post published June 25, 2026, stating rollout 'started including SynthID in Text to Speech generations by free users' with coverage expanding 'to all ElevenLabs audio generations over the coming weeks'; this predates the 2026-08-05 to 2026-08-19 window, and no ElevenLabs-published update specifically dated within the window was found. Included as backfill because no watermarking or detection-type provider policy is currently tracked for ElevenLabs (the existing entry covers only cloning consent). Flagging two things for the orchestrator to weigh before keeping this: (1) it is pre-window, not a change within 2026-08-05 to 2026-08-19; (2) the assigned lens is 'consent, verification, and takedown policy changes' and watermarking is a transparency/provenance mechanism, arguably a lens mismatch even though it is squarely in-topic. Companion primary source (help.elevenlabs.io audio-detector article) confirms verbatim: 'Watermarking is a digital technology designed to identify AI-generated content. It embeds imperceptible digital watermarks directly into AI-generated audio' and 'We believe people should know when they are interacting with AI-generated content, and watermarking is one of the most robust ways to provide that transparency.' Status normalized to 'in-effect' per this task's schema enum, diverging from the baseline's 'active' convention on the five existing provider-policy rows.
