Apple Watch can now replay what someone just said, in beta

Audio Intelligence is Apple's name for a group of four opt-in features that use the watch's microphone. All four need the newest watch models.

• Sound Recognition: spots important sounds like sirens, alarms and doorbells. It is aimed at deaf and hard-of-hearing users.
• Music Recognition: uses Apple's Shazam to name a song playing nearby, faster than before.
• Live Rewind: shows what someone just said, as text.
• Siri Recap: writes short notes about a conversation.

The first two are about sounds. The last two are about people talking, which is why they get the most attention.

Think of it as a rewind button for real life. Someone gives you directions, a waiter reads a long list of specials, or an airport announcement is too muffled to follow. You double-press the Digital Crown.

The watch then shows the last 15 seconds of speech as a text snippet on its screen. A chime plays and an animation appears, so the people near you can tell that something was captured. Apple says the chime plays even when the watch is on silent.

You have three choices once the text is up:

• Do nothing: the snippet disappears for good. Apple says unsaved snippets are deleted after 30 seconds.
• Ask Siri: tap the "Ask Siri" button under the text if you want to know what a word or a dish means.
• Save it: keep the snippet in the Siri app, the standalone app that arrived with iOS 27.

In real life You are at a trail start and a ranger says the route in one fast breath. You double-press the crown, read "stay left after the trail marker," and nobody has to say it twice.

Siri Recap goes further. It listens over a longer stretch and then writes notes for you. After a conversation, Apple Intelligence makes a title and a short list of key points.

It does not write down every word. Apple says the feature doesn't identify who said what, doesn't keep the raw audio and doesn't give a word-for-word transcript. It works more like a friend jotting down the main points.

Why it matters: a recap can catch dates, deadlines, prices and payment plans. Apple suggests uses like work meetings, parent-teacher conferences and personal training sessions, when your hands or your attention are busy.

Recaps don't record while you listen to music through headphones or use noise cancellation. They also leave out some sensitive details, such as government ID numbers and financial or login data.

Both features delete things quickly unless you choose to keep them.

• Live Rewind snippets: gone after 30 seconds if you don't save them.
• Siri Recaps: gone within seven days if you don't save them.
• Daily review: when Siri Recap is on, the watch asks you at the end of the day, and again when you first unlock it in the morning, which recaps to keep.
• Where saved notes go: the Notes app, or the Journal app if they are more personal.

You can switch Siri Recap on by hand or give it a schedule, like work hours only, or never at night. Even on a schedule, you can turn it off at any moment from the Control Center.

This is the question that decides whether people trust the feature. Apple's answer is built around the watch's S11 chip.

The chip has an always-on processor with a secure enclave, a locked-away piece of memory that the rest of the system can't read. A small audio buffer, a short holding area for sound, works inside it. Apple says the raw audio can't be reached by the operating system, by apps, by you or by Apple.

Light AI models on the watch pick out the parts that matter. The watch then passes the audio to your paired iPhone through a secure link. The iPhone runs Apple Intelligence models, and for a recap it can also use Private Cloud Compute, Apple's own servers built to process requests without keeping them.

Apple says the recap and anything used to make it are deleted from those servers right away. The finished recap is only readable by you, and it is encrypted when it syncs between your Apple devices. Apple also says none of this should hurt battery life on the watch or the phone.

The catch: an always-on microphone raises fair questions. Apple's design is a set of promises about what the system does, and the chime, the animation and the opt-in switches are how it tries to make the listening visible.

Gadgets that listen to people have run into backlash. AI glasses, like Meta's, and other AI wearables have made many people uneasy about being recorded without a clear sign.

Apple's answer is to copy what a person already does. You can jot down a note about a talk in your own words. A recap is meant to do the same: key points, with no tone and no emotion, and no record of who said which line.

The design choices all point the same way:

• A chime and an animation: they tell people nearby that Live Rewind was used.
• A microphone indicator: it shows on the screen while the feature is in use.
• No speaker names: Audio Intelligence doesn't identify or label who is talking.
• Opt-in switches: some of the features have to be turned on by hand, and each can be turned off.

Whether that is enough is up to each person. Some users will leave Siri Recap off, and that is a normal choice.

The Siri app is the standalone app that came with iOS 27. It is the home for what you choose to keep. Saved Live Rewind snippets go there, and so do the titles and key points from Siri Recap, so you can look them up when you need to jog your memory.

The checklist is long, and it is the main reason most people can't test it yet.

• Watch: an Apple Watch Series 12 or Apple Watch Ultra 4.
• Phone: an iPhone 16 or later with Apple Intelligence on. The iPhone 16e is not included.
• Software: the watchOS 27.3 beta, aimed first at developers.
• Language and place: English only, and not in the EU.
• Limits: both features have daily usage limits.

What's next: the features move to the public beta for wider testing, and then they are meant to reach everyone. Apple has not named a date.

• If you own a Series 12 or Ultra 4: you can try these now through the beta, but expect rough edges. Betas are for testing.
• If you own an older watch: nothing changes. These features rely on the S11 chip.
• If you care about privacy: read the settings first. Both features are opt-in, and you can turn them off.
• If you talk to people near you: the chime is the signal. Expect questions if you use Live Rewind in a quiet room.
• If you live in the EU: you will have to wait, as the features are not available there.
