Does Sonos train on your data?
Sonos's September 2026 statement sends 27voice commands to its cloud for "AI-assisted processing" and shares voice data with AI partners. It still never says whether any of it trains a model.
Re-read on 10 September 2026 against the statement Sonos published that month, 182 paragraphs saved by hand because the host serves the monitor an empty shell. It is a bigger document than the one read on 6 September: a "Sonos 27voice" upgrade now sends "voice recordings, transcripts, AI-inferred command intent, and command metadata" to Sonos cloud infrastructure for "AI-assisted processing", where the classic voice control kept everything on the device; an "Artificial intelligence ("AI") partners" section shares that voice data with the partners that provide the feature; and ambient-noise data is collected "to help us improve our speech recognition technology". None of it says "train", "model" or "machine learning". The speech-recognition sentence is the nearest, and it is the improvement boilerplate this site declines to grade on: it tells you the technology is improved, not that your recordings are the material. Whether recordings, transcripts or listening history train anything remains unstated, so the finding of silence stands, on a document that now has more to be silent about.

Both hits are "artificial intelligence" as the name of a technology: the "Artificial intelligence ("AI") partners" heading of the section on sharing voice data with the partners behind Sonos 27voice, and its definition of "AI". Neither is a use of your data to build one; no form of "train" appears anywhere in either version.

How to opt out of Sonos AI training
Plan by plan, from what Sonos's own policy says about refusing. Where it publishes the steps, they're listed here with the limits they carry. Where there's nothing to switch off, or nothing graded, this says so instead of inventing a menu path.

What this policy has done since we started watching
No change detected. We've held a copy of Sonos's policy since 6 Sept 2026 and re-read it since, across 3 captures. The text hasn't moved in a way that touches this verdict. That's a fact about the document, and it's only knowable by having kept the earlier copies.
