How It Works
Six steps.
Under a second.
From the moment you speak to the moment every participant in their native language understands you.
🎙️
01 Capture

Browser microphone captures your voice at 16kHz mono — optimal for speech, minimal bandwidth

📡
02 Stream

Audio streams via WebRTC to the KWIVO SFU server — encrypted, low-latency, peer-optimised

🧠
03 Transcribe

AI speech recognition converts your voice to text in real time — partial results appear immediately

🌐
04 Translate

Text is translated simultaneously into every listener's language — one API call per unique language

🔊
05 Synthesise

Translated text is converted to natural-sounding speech in the listener's language on demand

✨
06 Deliver

Subtitles and audio arrive at each participant — all in their native language, seamlessly

Total end-to-end: <800ms — faster than a human interpreter can form a thought
Features
Built for meetings
that matter.
🎯
Real-time subtitle overlay
Translated text appears on screen as the speaker talks — not after they finish. Partial results update live, finalised text replaces them cleanly.
Live · <300ms
🔊
Translated voice output
Each listener can optionally hear the translation spoken aloud in their language. Voice output is per-participant — you choose, they choose independently.
Per-listener · Optional
📝
AI meeting summaries
After each meeting, an AI-generated audio summary is produced in every participant's language. Key decisions and action items, ready in 10–15 minutes.
Post-meeting · Async
📶
Low-bandwidth mode
Automatically detects poor network conditions and switches to text-only mode. Works on connections as slow as 8kbps — essential for users across Africa and emerging markets.
Adaptive · Auto
🔐
End-to-end encrypted
All audio streams are encrypted via DTLS. No recordings are stored without explicit consent. Meeting data is ephemeral — translations are streamed and discarded.

Live Meeting Experience
What it looks
like inside.
  • 🗣️
    Speaking indicator
    A glowing ring highlights whoever is currently speaking. Language flag shows which language they're speaking in.
  • 💬
    Live translation bar
    Translated text appears at the bottom of the screen — the original sentence alongside the translation, always visible.
  • ⚡
    Instant, not delayed
    Words appear as they are spoken — not after the sentence finishes. The experience feels like a live conversation, not a dubbed video.

What people say
Real words from
real meetings.
★★★★★
We run weekly calls with teams in Japan, Germany, and Brazil. KWIVO eliminated the 10-minute "can you repeat that" cycle we used to have at the start of every meeting.

★★★★★
The latency is genuinely impressive. I was sceptical that "under 800ms" was marketing speak — but in the demo meeting the subtitles appeared while the speaker was still talking.

★★★★★
We're a Pan-African startup with no common language across all founders. KWIVO is the first tool that actually lets everyone speak comfortably in their own language.
