oto listens to your voice and speaks it back in another language — live, hands-free, in under a second. Thirteen languages, one conversation.
You say “Hello” — they hear HolaBonjourこんにちは안녕하세요OláHola
Talk the way you always do. oto streams your voice to the model as you go — no push-to-talk, no waiting.
OpenAI's realtime model interprets your speech in under a second, preserving meaning and tone.
The translation plays out loud in a natural voice and appears as text — both sides follow along.
Your words and their translation stream in side by side, so nothing gets lost. Tap a language, hit start, and talk — oto handles the rest while your API key stays safely on the server.
