苹果 watchOS 27.3 开发者测试版上线 Audio Intelligence 常驻监听功能
Apple’s latest watchOS beta includes its new always-on Audio Intelligence features
苹果在 watchOS 27.3 开发者测试版中推出 Audio Intelligence 功能，Siri 可接入 Apple Watch 麦克风。新增的 Siri Recap 通过环境监听生成对话摘要，Live Rewind 则生成手表麦克风最近 15 秒音频的文字转录。苹果同时发布隐私说明，称原始音频在专用硬件内处理、不保存为文件，操作系统、应用和苹果均无法访问；用户选择保存的摘要或转录片段会经端到端加密在 Siri 应用中跨设备同步。iOS 27.3 开发者测试版还开放了重新设计的健康应用测试，新增 Insights 标签页和 For You 个性化推荐，并扩展了简体中文、繁体中文、法语、日语、韩语等语言支持。

Starting today, Siri can tune into the Apple Watch’s mic with Audio Intelligence features that are available in the new watchOS 27.3 developer beta rolling out now. The two new additions are Siri Recap, which uses “ambient listening” to generate summaries of your conversation, and Live Rewind, which generates text transcripts of the last 15 seconds of audio your watch’s mic detected.
Apple is also releasing its redesigned Health app for testing today in the iOS 27.3 developer beta, and announced expanded language support in global English, Chinese (Simplified and Traditional), French, Japanese, Korean, Norwegian, Portuguese, Spanish, Turkish, and Vietnamese. It adds sections like a new Insights tab with summaries for heart, sleep, fitness, and other data that pop up during the day, a For You section with personalized recommendations, and health content like educational videos and articles.
When it comes to the implications of an ambient, always-listening AI, Apple has released this Audio Intelligence Privacy Overview (pdf) about how it plans to protect users’ privacy when their watch is listening around the clock. It goes into detail about Apple’s claims that users’ raw audio “is handled within dedicated hardware, is not saved as a file, and is not accessible to the operating system, apps, or Apple.” According to Apple, “If you use iCloud with two-factor authentication and have a device passcode, any Siri Recap summary or Live Rewind text snippet you choose to save syncs across your devices end-to-end encrypted in the Siri app.”
