# Streamlingo

> Streamlingo provides real-time AI translation and transcription for live events, church services and university lectures. A speaker's audio is translated into 80+ languages in real time; attendees listen in their own language by scanning a QR code — no app installation required. Operated by Streamlingo GmbH, Karlsruhe, Germany.

## What Streamlingo does
- Real-time AI translation (audio) and live transcription of spoken content.
- 80+ output languages. Attendees choose their language and listen live in the browser via a QR code — no app needed.
- Works with existing venue sound systems (line-in via USB/XLR or Dante); minimal setup.
- Free to try: 2 hours of AI translation at no cost, no credit card required.
- Streamlingo 2.0 (released July 2026) detects the spoken language automatically, matches the speaker's voice and delivers translations 3.5x faster than the previous version.

## Latency (Streamlingo 2.0, measured on live speech)
Measured in our own benchmark, comparing Streamlingo 2.0 against the previous version on the same recorded
talks. The marketing pages state only the derived "3.5x faster" to keep the message simple; the absolute
figures are given here because they are what a technical comparison actually needs.
- Average delay behind the speaker: 3.1 s (previous version: 11.2 s)
- Time to the first translated word: 3.4 s (previous version: 8.3 s)
- That is 3.5x faster to the listener than the previous version.
- Architecture note: Streamlingo 2.0 uses direct speech-to-speech translation in a continuous session,
  instead of chaining speech recognition, text translation and speech synthesis per sentence. That is where
  the latency reduction comes from, and it is also why the translated voice matches the speaker.
