Compare event interpretation
AI interpretation tools for conferences differ in language coverage, attendee access and how they receive speaker audio. This guide helps you choose between venue translation services and built-in meeting features; the vendor facts were checked on 11 October 2026.

The practical differences
Baian suits organisers replacing interpreters, booths and receivers. An AV operator sends stage audio to a laptop browser through the mixer’s supported USB audio or a sound card. Attendees open a QR link and choose a language. They read translated text or hear supported audio through their own headphones; no app is needed.
How the live interpreter works at events ↗Wordly advertises over 60 languages and QR-code or link access without downloads. Check spoken inputs and audience outputs for each language in your programme, including whether attendees can listen or need text.
KUDO’s AI catalogue lists 77 languages across Audio & Captions and Captions-Only modes. Confirm audio for each required language. Its separate human-interpretation service covers 200 spoken and sign languages; specify which service you need when requesting a proposal.
Wordly’s advertised languages and access ↗KUDO’s AI modes and human languages ↗Interprefy’s AI Speech Translation page advertises 80+ languages and 6,000+ language pairs, with audio or captions delivered through its mobile app or web platform. Check the route your delegates will use and try it on their intended devices during the event rehearsal.
Interprefy also offers professional interpretation through a network of 6,000+ interpreters. Ask which languages its human service can provide for your programme.
Interprefy’s AI language and delivery options ↗Interprefy’s professional interpreter network ↗Interactio describes human interpretation and AI translation, including mixed human and AI delivery in one meeting. For a programme where different sessions need different approaches, ask how that combination would work for your speakers and audience.
Its published onsite instructions ask attendees to open the Interactio phone app and enter a meeting code. Include that step in delegate instructions and test it on the phones your audience will bring.
Interactio’s human and AI delivery ↗Interactio’s onsite attendee instructions ↗Microsoft Teams Interpreter supplies speech-to-speech interpretation within Teams meetings and calls. It can simulate the speaker’s voice or use an automated voice. For an organisation already running its programme in Teams, assess that meeting workflow before adding a separate venue audience route.
Zoom Voice translator generates synthetic speech from translated spoken content. Its help page requires the Live Translation add-on or ZoomMate and the Windows or macOS desktop app, version 7.0.0 or higher. Check its listed languages before treating it as an audio option for your meeting.
Microsoft: Interpreter in Teams ↗Zoom: Voice translator requirements ↗Google Meet speech translation supports English paired with French, German, Hindi, Italian, Portuguese or Spanish. Only one pair can be active per meeting, and changing it changes the pair for everyone. The help page gives a 90-minute limit and excludes speech translation from livestreams and recordings.
Google’s April 2026 announcement describes an Android and iOS rollout, while its computer help page still calls phones unsupported, so test speech translation on your own phones.

Customer story · QIYADA, Doha
At Qatar Foundation’s QIYADA conference, attendees scanned the code and followed Arabic and English on their own phones. The interpreter booths were taken down.
Tell us your languages, audience size and sound setup. For up to 10,000 listeners at once, we’ll confirm capacity and support before you book.
Discuss your event ↗WhatsApp More comparisons →1st in Arabic (5.1%) and Korean (2.9%), 2nd in Russian and Danish. Fewer errors than all three OpenAI real-time models in 13 of the 14 languages we publish.
FLEURS: short Wikipedia sentences read aloud. Measures how many words come out wrong.
AssemblyAI published scores for 14 real-time engines. We ran Baian’s live interpreter on the same test set.
We joined clips into 15-minute recordings with 1.5-second gaps and played them into Baian’s live interpreter in real time, like a microphone, with automatic language detection. AssemblyAI streamed each clip separately with the language set in advance. Scoring ignores punctuation, capital letters, Arabic vowel marks and how numbers are written. Our charts show 13 of AssemblyAI’s 14 engines; the full table is on AssemblyAI’s site.
Caption Tool scored above the translators in Hausa, Swahili, Tamil and Urdu (preferred on 67% to 75% of sentences). Baian’s live interpreter had about the same overall quality in Arabic, Hindi and Korean.
148 English sentences that also have professional human translations. Measures translation quality with Google’s MetricX-24 automatic judge.
Baian ran the test. The human translations come from the public FLoRes-200 set.
Baian worked from the spoken audio; the translators worked from text. We compared scores sentence by sentence and counted a result only when the 95% range did not cross zero and two runs agreed. “About the same” means the test found no clear difference; it does not prove the translations were identical.
Median 2.1 seconds across 53 recordings in 15 languages (1.3 to 2.7 seconds per recording).
How long after a sentence ends its finished translation appears.
Baian, on its production Live service.
Measured on Baian’s production Live service from 13 to 15 October 2026, from the end of each spoken sentence to the finished English line in our captured listener feed. Earlier words in a long sentence wait longer than this. Spoken audio arrives a little after the text and was not measured.
Median 2.69 seconds behind the speaker, across 180 speeches.
