At WWDC 2025, Apple unveiled a major breakthrough: live translation across Messages, FaceTime, and Phone calls. Using its proprietary Apple Intelligence system, the feature enables real-time translation all performed on-device—no external servers involved, preserving user privacy while ensuring speed and responsiveness

With this update, users can speak in one language and have it instantly translated in a conversation, making cross-language communication seamless. Apple demonstrated how two users speaking different languages could interact naturally in Messages and FaceTime, with translated subtitles or audio delivered instantly.
This advancement reflects Apples ambition to blend AI capabilities into everyday features, while maintaining strong privacy. The custom AI models running natively on devices are power‑efficient and secure, avoiding latency and safeguarding personal data. The move positions Apple beyond typical translation apps and highlights an increasing shift toward on-device AI capabilities—particularly important in sensitive areas like health and communications.
As part of the update, Apple hinted at broader integration of live translation into other apps such as Apple Retail, and expanded voice‑to‑text translations without relying on cloud processing. The announcement reinforces their push toward privacy‑preserving AI that operates fully offline.
This innovation could be a game-changer for travelers, international business users, and multilingual families. It positions Apple to compete more directly with third-party translation services like Google Translate and emerging AI chat tools, but with a strong privacy edge. Analysts suggest that the real‑time translation feature may soon extend to CarPlay, AirPods, and other Apple ecosystems, making linguistically adaptive communication a seamless part of daily life.
