Live Translation captures speech through your smart glasses microphone, transcribes it in real time, and displays translated text on your HUD — all without lifting a finger.

• Real-time translation — Transcribes and translates speech as it happens
• 100+ languages — Supports a wide range of source and target languages
• Intelligent display — Confidence-based filtering prevents flickering mid-word corrections
• Adaptive layout — Text wrapping and formatting tuned for AR displays
• Auto-clear — Display clears after 40 seconds of silence
