Siri on Apple Watch can remember useful parts of your day without retaining everything

Your Apple Watch now utilizes all-day audio listening to compile a daily Siri Recap based on sounds around you. It does this by forgetting the audio the moment it comprehends the context. Siri Recap Audio Intelligence employs Sound Recognition to discern pertinent information from the user's environment as events unfold. Siri can merge these signals with other accessible data to generate a summary of the day later.

Sound Recognition can recognize events like sirens, alarms, doorbells, and crying babies, which could prove beneficial for safety and accessibility. A separate Live Rewind feature allows users to double-press the Digital Crown to replay the past 15 seconds of detected audio and view a transcript. However, the resulting Siri Recap does not include transcripts of overheard conversations, and Apple asserts the feature does not store audio. Sound processing occurs continuously before the original audio is discarded.
