Overview

• Voice Captioning is the latest Galaxy AI feature in Samsung’s Android 16-based One UI 8, offering live speech-to-text conversion across videos, calls and in-person conversations.
• Beyond basic captions, the tool can translate spoken words into multiple languages on the fly, surpassing the capabilities of Samsung’s existing Live Captions.
• Users can generate concise summaries of spoken content and export both the transcribed text and original audio files for review or sharing.
• As of August 4, 2025, Samsung has confined the feature to the China-only One UI 8 build and has not announced a global release date.
• Galaxy users outside China can manually unlock Voice Captioning by downloading and sideloading a leaked APK, though stability and performance may vary.
