AI simultaneous interpretation services without booths

Simultaneous interpretation lets listeners hear a speech in their language while it is being given. Event Translate delivers it with AI to attendees’ phones, with no booths or receiver kits.

Simultaneous interpretation

Why use live AI translation for simultaneous interpretation?

No booths or receiver kits

Attendees listen on their own phones and headphones, so there are no interpretation booths to build, no receivers to hand out and none to collect at the end.

Languages without interpreter pairs

Simultaneous interpretation usually needs two interpreters per language working in turns. Here each extra language is a setting, so a smaller audience group still gets served.

Built for conference interpretation

Keynotes, panels and Q&A run at the normal pace. Isolated Multi-mic channels keep panel speakers separate, and the glossary holds speaker and product names.

Priced per event, not per day rate

On-demand credits follow minutes and languages, with no listener fees and no monthly or annual commitment for a one-off conference.

How to set up live translation for simultaneous interpretation

The source feed is the first decision: take it from the mixer the production desk already runs, then test the listener path with the languages and audience you expect.

  1. Take a feed from the mixer

    Create the Stage, choose the source and target languages, then connect the venue mixer as a mixed mono feed or two isolated L/R channels.

  2. Rehearse with real speech

    Test panel handovers, audience questions and representative terminology. Treat around 0.5 s of translation delay after a natural speech break as a planning reference.

  3. Replace the receiver desk with a QR code

    Put the QR code on badges, signage and the opening slide. Attendees choose a language on their phone and listen with their own headphones.

Mixed mono for a shared feed

Use the room’s combined feed when the desk already delivers clear, balanced speech and you want the simpler 1× usage path.

Isolated stereo Multi-mic

Use two isolated L/R channels when panel microphones need independent processing. This Multi-mic mode uses the shared 2× credit factor.

Audio and live captions

Each listener hears translated speech or reads live captions, without changing the room mix or the running order.

Estimate simultaneous interpretation 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.

Mixed mono

One combined feed from the venue mixer.

1 hour × 2 target languages × 1 = 120 credits

Isolated stereo Multi-mic

Separate panel mic channels for independent processing.

1 hour × 2 target languages × 2 = 240 credits

  • Listeners do not add to the price, so the cost stays the same whether 20 or 500 people connect.
  • Allow about 100 kbps per connected listener when checking the venue network.
  • Two parallel rooms in the same account depend on the account’s current multi-room access. Check the plan in Console first.

Live translation for simultaneous interpretation: FAQ

What is simultaneous interpretation?

Simultaneous interpretation renders a speech into another language while the speaker is still talking, so listeners follow in real time. Traditionally interpreters work in soundproof booths and the audience listens on receivers; AI simultaneous interpretation delivers the same live result to attendees’ phones.

What is the difference between simultaneous and consecutive interpretation?

In consecutive interpretation the speaker pauses after each passage while the interpreter repeats it, which roughly doubles the time. Simultaneous interpretation runs alongside the speech, so the programme keeps its normal length.

Do we still need interpretation booths and headsets?

No booths or receivers are needed. Attendees scan a QR code, choose a language in their phone browser and use their own headphones for translated audio, or read live captions instead.

When is a human simultaneous interpreter still the better choice?

Choose qualified human interpreters when every nuance carries legal, medical or diplomatic risk, or when a language you need is not supported. Many events use AI for most languages and humans where the stakes are highest.
