Features
No robotic delays, no awkward pauses. Ktranslate listens, translates, and speaks back in natural voices — in under a second.
Ktranslate streams audio the moment you start speaking — no waiting for the sentence to end, no app tap-dance.
From English and Japanese to Hindi, Vietnamese, Arabic, and Ukrainian — pick any two sides of the conversation.
Two push-to-talk panes on one screen — the listener's side is flipped 180° so your partner reads it right-side up. Hold to speak, release to hear the translation.
With headphones, your ear hears your translation, your partner's ear hears theirs. One phone, zero overlap, completely private conversation.
Hold the phone up to a speaker — a phone call on loudspeaker, a gate announcement, someone across a counter. Get the translation on your side, one-way.
How it works
Choose one language for each side from a dropdown. Your last selection is remembered for next time.
Each side has its own push-to-talk. The listener's pane is rotated 180° — your partner reads their translation right-side up.
The translation plays back on your partner's side. Wearing headphones? Each translation lands in the right ear automatically.

Audio is streamed to our server for translation and is not stored after your session ends. Fully on-device translation is not available yet.
