iOS 27 can generate subtitles for video by itself. Apple’s wording is that the system automatically generates synced subtitles for any video you watch, and that it can translate existing captions into other languages. It arrives with the free update on Monday, September 14.
That single sentence is close to the entire published record, which is a problem, because this is the most consequential accessibility change in the release. Captions on the web are still a lottery: they exist when whoever uploaded the video bothered. A system that makes its own removes that dependency for deaf and hard-of-hearing viewers, and helps anyone watching in a language they are still learning.

What “any video” appears to cover
Apple’s phrase is any video you watch, not any video in Apple’s apps, which reads as system-level rather than app-level captioning. Apple has not confirmed that reading, and has not said whether protected streaming video, video in third-party apps, live streams or muted autoplay clips are included.

The second half of the sentence is narrower than the first and easy to miss. Apple describes translating existing captions, which is a different job from translating audio it has just transcribed. Whether a video with no captions at all can be transcribed and then translated in one pass is not something Apple has stated.
Who gets the most out of it
The obvious group is deaf and hard-of-hearing viewers, who currently work around uncaptioned video with third-party tools, guesswork or by skipping it. A system-level caption track that appears without being asked for changes the default from nothing to something on every video an iPhone plays.
The translation half serves a second group: people watching in a language they read better than they hear, and anyone dealing with a video published in a language they do not speak. There is a third group that Apple does not mention and that every accessibility feature ends up serving anyway, which is everyone watching with the sound off on a train.
Three different iOS 27 features turn speech into text
Automatic captions are easy to confuse with two other Apple features announced in the same cycle. They do different jobs, need different hardware and arrive on different dates.
| Feature | What it handles | Requirement Apple published | When |
|---|---|---|---|
| Auto-generated subtitles | Video you watch on the device | iOS 27; device list not published | September 14 |
| Live Translation | Texts in Messages, live captions in FaceTime and phone calls | Apple Intelligence device; Apple lists it as available now | Available now |
| Live Translation with AirPods | In-person conversation with someone in front of you | AirPods 4 with ANC, AirPods Pro 2, AirPods Pro 3 or AirPods Max 2, with iPhone 15 Pro or later | Available now |
| Live Rewind on Apple Watch | The previous 15 seconds of a conversation, as a text snippet | Apple Watch Series 12 or Ultra 4 with an Apple Intelligence iPhone | Beta later in 2026 |
The AirPods 5 announced on September 9 are not on Apple’s Live Translation hardware list as published, and Apple has not said whether they will be added. Apple Watch Series 12 handles the wrist end of this through Audio Intelligence, which is a separate feature set gated to the new watches.
The requirements Apple has published, and the one it has not
iOS 27 installs on iPhone 11 and later plus iPhone SE (2nd generation and later), which is a wide net. Apple Intelligence is much narrower: iPhone 15 Pro, iPhone 15 Pro Max and iPhone 16 or later, in 16 languages.
Apple has not said which side of that line automatic captioning falls on. Speech recognition of this kind is computationally heavy, so the question is not academic for anyone holding an iPhone 11, 12, 13 or a non-Pro iPhone 14. Until Apple publishes it, treat the feature as confirmed for iOS 27 and unconfirmed for your specific model.
What Apple has not said
The list of gaps is long: the languages subtitles can be generated in, the languages captions can be translated into, whether an Apple Intelligence iPhone is required, whether transcription happens on device or through Private Cloud Compute, whether the feature counts against the daily usage limits Apple applies to server-based features, which apps and video types are covered, and whether the existing Subtitles and Captioning styling controls apply to the generated text.
Regional coverage is unstated too. Apple has confirmed that Siri AI is not initially available in the European Union on iOS, iPadOS and watchOS and that new Apple Intelligence features are not available in China while regulatory work continues, but it has not said whether captioning is affected by either.
iOS 27 ships free on Monday, September 14, and Apple’s release notes are where the missing detail normally appears. Our iOS 27 release guide has the timing, and the event recap covers everything else Apple announced on September 9.
