60+ languages. One dropdown. Or zero setup.
Each participant selects the language they speak and the language they want to hear — independently. Or use auto-detect: TellAcross identifies what language you're speaking automatically and routes translation accordingly. Switch languages mid-call and it keeps up without interruption.
Participant language setup
TellAcross handles everything in real time.
The moment you start talking, TellAcross captures your voice, transcribes it with high accuracy, translates it into your partner's language, and plays it back — all in under 1.5 seconds. You just have a conversation. The technology disappears.

Everything captured. Nothing missed.
Every word spoken in every language is logged in the scrollable transcript panel with speaker attribution, timestamps, and original + translated text side by side. After the call, export to PDF or copy the full log for meeting notes, auditing, or review.

Not every conversation happens over a call. Quick Translate lets you translate in real time with someone standing right in front of you — no room code, no second device. One person speaks, the other hears their language, right on the same screen.

Why this is hard to build
Every company says "real-time." Almost none mean it. Here is what we solved that others didn't.
Under 1 second, end-to-end
Getting from the last word you speak to translated audio playing in your partner's ear in under one second requires solving dozens of micro-latency problems simultaneously. Most systems buffer, batch, and process in rounds. Ours streams continuously — the moment a sentence completes, the output is already halfway done.
Conversations, not sentences
Translating one sentence accurately is trivial. Translating a conversation accurately is not. Names mentioned 5 turns ago need to carry into the current sentence. A pronoun said in Hindi needs to resolve correctly in German. Industry vocabulary — medical, legal, financial — needs to hold across every exchange. We built a conversational memory layer that no sentence-by-sentence system can replicate.
Sounds human, not robotic
The final output has to sound like a real person said it — not a machine reading a translation. Speaking pace, emotional tone, the natural rhythm of a sentence in the target language — all of this has to be preserved or reconstructed. A robotic voice breaks trust and makes comprehension harder. We spent significant time on this layer and it shows.
The result: a system that feels less like software and more like having a fluent interpreter in the room.
