Sim Trans is a translation and interpretation company first. We use AI where it serves the people in the room, and we are honest about where it does not. This statement explains how SIM.AI works, how we oversee it and what its limits are.
How we use AI
SIM.AI combines three kinds of AI to interpret speech live:
| Step | What it does |
|---|---|
| Speech recognition | Turns the speaker’s words from the venue audio feed into text in the original language |
| Machine translation | Translates that text into each language the organiser has chosen |
| Speech synthesis | Speaks the translation aloud in a natural voice, so guests can listen in their earbuds |
Guests can listen to the audio, read live captions, or both. The interpretation runs a few seconds behind the speaker. Our how it works page shows the full set-up.
We use carefully selected providers for these steps. We describe them by category on our sub-processors page, and give clients the named list on request.
Human oversight
AI never runs our events on its own. Our team monitors every language channel live, throughout every session. They check the audio feed and the output, and step in when something goes wrong, for example by fixing an audio problem or adjusting a session setting.
Before the event, we work with the organiser on the venue audio, the languages and the glossary. After the event, the organiser receives recordings, transcripts and subtitle files they can review.
Known limitations
Machine interpretation can contain errors. They are more likely with:
- Names of people, places and organisations, especially uncommon ones;
- Accents, particularly strong regional accents or speakers using a second language;
- Overlapping speech, when several people talk at once;
- Poor audio, such as a room microphone, background noise or a speaker away from the microphone;
- Idiom and humour, which may not translate literally;
- Specialised terms, such as legal, medical or technical vocabulary.
A clean audio feed from the venue sound desk makes the biggest difference. Our guide to preparing a glossary helps with the rest.
How we reduce errors
- Custom glossary: the organiser’s names, titles, product names and legal terms are applied consistently.
- Precision mode: terminology and pronunciation are enforced for legal, government and technical sessions.
- Audio set-up: we connect to the venue’s own sound system for a clean feed.
- Live monitoring: our team watches every channel throughout.
A glossary and Precision mode reduce errors. They do not remove them.
When to choose human interpreters
For legally binding proceedings, sensitive negotiations, medical consent, VIP protocol, or any session where every word matters, choose certified human interpreters, or a hybrid set-up that combines human interpreters for key sessions with AI for the rest. Sim Trans provides both. Our AI and human interpretation page explains how a hybrid set-up works.
Interpretations, captions and transcripts should not be used to make decisions with legal, medical or similarly significant effects on people without proper human review.
Transparency to guests
Guests should know when they are listening to machine interpretation. We ask organisers to tell them, and we help:
- we suggest a line for the event card or QR table card, such as: “Live interpretation at this event is provided by AI and monitored by our team.”;
- the organiser can repeat it in the opening remarks or on screen;
- where sessions are recorded, organisers should tell speakers and guests.
How we treat your event content
Event content belongs to the organiser. We use it only to deliver the service and produce the records the organiser orders. We keep it only as long as the organiser wants, and delete it on request.
We do not use your event content to train our own models, and we select providers whose terms do not permit them to train on it.
Data is processed in the EU region by default, and UAE processing is available on request. Our privacy policy gives the full details.
Accessibility
Live captions can help guests who are deaf or hard of hearing, and guests who prefer to read along. Guests can choose captions only, and can show the original language alongside the translation.
Machine captions can contain errors. Where guests rely on captions or sign language for access, organisers should consider whether human captioning or sign language interpretation is also needed. Our accessibility statement covers the website.
Feedback
If you notice an error, a bias or anything that concerns you about how SIM.AI interprets speech, please tell us at ai@sim-trans.com. We review every report and use it to improve how we configure and run the service.
We review this statement as our services and the law develop. The date at the top shows when it was last updated.
