Speech in, speech out
Listeners hear translated speech, not just captions, so their eyes stay on the speaker, the stage or the route. Captions run on the same page for anyone who prefers to read.
Live audio translation from any mic to every phone
Event Translate translates live audio: it takes speech from a microphone or mixer and plays it back as translated AI voice and captions on each listener’s phone.
Why use live AI translation for live audio?
A voice that keeps the speaker’s pace
Each language channel uses a natural AI voice that adjusts its speed to match the speaker, so the translation keeps up with a fast talk and stays calm in a slow one.
Any audio source you already have
A handheld or lapel mic, the venue mixer through a USB audio interface, or a phone with a lavalier on a walking tour. A clean speech signal is all it needs.
Many languages from one feed
One audio feed can reach 35 target languages, several at once. Speakers can use any of 70+ languages and switch mid-talk; the system detects it automatically.

How to set up live translation for live audio
Audio quality decides translation quality: start from the cleanest speech feed you have, then test what listeners hear on their phones.
Connect the audio
Create the Stage, choose the target languages and connect the microphone or mixer output. Use the cleanest, driest speech signal you can, with little reverb, music or room noise.
Tune and rehearse
Adjust the noise gate and voice-detection sensitivity while you listen, then rehearse with real speech. Treat around 0.5 s of translation delay after a natural speech break as a planning reference.
Share the QR code
Listeners scan it, choose a language in their phone browser and listen through their own headphones. They can switch language at any time without rejoining.
Mixed mono or isolated stereo
Send one combined feed at the 1× rate, or two isolated L/R channels when two voices need independent processing. This Multi-mic mode uses the shared 2× credit factor.
Audio and captions together
Every target language arrives as translated audio and a live transcript, so each listener chooses headphones, captions or both.
Recovers from network drops
After a brief drop, the operator and listeners reconnect on their own, and audio and transcripts resume without anyone re-scanning the QR code.
Estimate live audio translation credits
Credits follow broadcast time, target languages and mic mode. This illustration uses one hour and two target languages; use the pricing calculator for your own programme.
On-demand credits start from £4 an hour for one target language, with no monthly or annual fee.
One mic or mixer feed
A single microphone or combined venue feed.
1 hour × 2 target languages × 1 = 120 credits
Isolated stereo Multi-mic
Two isolated L/R channels for two voices processed independently.
1 hour × 2 target languages × 2 = 240 credits
- Listeners do not add to the price: the cost depends on minutes, target languages and mic mode only.
- Stop the Stage during breaks and music, so usage follows active speaking time.
- For a one-off event, on-demand credits fit best; for regular sessions, compare the monthly plan on the pricing page.
Live translation for live audio: FAQ
What is live audio translation?
Live audio translation turns spoken audio into another language while it is being spoken and plays the result back as audio. Event Translate takes a microphone or mixer feed, translates each phrase with AI and streams a natural voice and captions to every listener’s phone.
How much delay does live audio translation add?
Translation typically starts arriving around 0.5 seconds after a natural speech pause. The full delay varies with the speech and connectivity, so rehearse with the real speaker and audio feed.
What audio equipment do we need?
A laptop or phone with reliable internet and a clear speech feed: a microphone, or the venue mixer through a compatible USB audio interface. Listeners need their own phones, plus headphones for audio.
Do more listeners cost more?
No. Credits follow broadcast minutes, target languages and mic mode only. Allow about 100 kbps per connected listener when you check the venue network.
