Select any word on the page just by speaking it aloud.
When both hands are on the book, saying a word out loud is faster than reaching for the screen. Lupa listens, matches what you said against the words it can see, and selects it.
How to use it
Hold the camera over the page. Wait for the page to stabilize.
Press and hold anywhere on the screen. You'll feel a short haptic — Lupa is now listening.
Say the word clearly.
Release. The matching word on the page is selected and the definition appears.
When it works best
Quiet rooms. Background noise hurts recognition.
Words of three or more letters. Short words like a or I are harder to match unambiguously.
Words that are actually visible in frame. Lupa only matches against what it can see.
If the match is wrong, just tap the correct word — the tap always wins over the voice match.
