Apple Unveils New Accessibility Features for tvOS 27 on Apple TV 4K

Apple disclosed that tvOS 27, slated for the Apple TV 4K, will add three major accessibility tools. First, a system-wide text-size setting, powered by Dynamic Type, will enlarge descriptions on the Home screen, menus, and supported apps. Second, a live-transcription engine will generate subtitles for video content lacking captions, processing audio locally on the device’s chip. Third, hearing aids certified for “Made for iPhone” will receive an AirPods-style seamless audio handoff, allowing users to route TV sound directly to their aids with minimal setup.

The updates extend Apple’s ecosystem-wide accessibility push, which already includes Dynamic Type and hearing-aid support on iPhone, iPad, Mac, and Vision Pro, making tvOS the first set-top box to receive these tools.

Apple has not formally launched tvOS 27. One source indicates a presentation at WWDC 2026 on June 8, while another suggests a demonstration at WWDC 2025 “next month.” Both imply that the features will roll out later in the year, but the exact release schedule remains unclear.

Apple says subtitle generation runs entirely on-device, preserving privacy. Dynamic Type scaling will apply to any app using Apple’s framework, mirroring iOS behavior. Made-for-iPhone hearing aids will automatically pair with Apple TV 4K, offering the same seamless transition across iOS, iPadOS, macOS and visionOS.

Developers using proprietary video stacks instead of Apple’s native APIs may not benefit. Netflix and Prime Video currently rely on their own playback frameworks, which could block dynamic text scaling and auto-generated subtitles.

The article gives two different WWDC dates—June 8 2026 and “next month” at WWDC 2025—leaving the announcement timeline unclear. The live-transcription feature is also limited to English with no schedule for additional languages.
