Professional interpreterAI

Interpreting set up in three steps

Simultaneous interpretation used to mean booth installations and rented headsets. With simultane.ai, use interpreters or AI and share one link with your listeners.

  1. Connect the speaker's audio

    Plug in the venue mixing desk, use a laptop microphone, or connect your Zoom, Teams or Google Meet session.

  2. Choose languages and mode

    Open as many language channels as you need and pick a professional interpreter or AI for each. Add names and terms to the glossary.

  3. Share the QR code

    Listeners scan, pick a language and listen with their own earphones, or follow translated captions on screen.

The right interpreter for every language channel

simultane.ai is not just an AI translation tool. Work with professional simultaneous interpreters, with AI, or combine both at the same event.

  • Professional interpreter

    Experienced simultaneous interpreters connect to the platform remotely or broadcast from a booth at the venue. For the event's main language pair and content where nuance matters.

  • AI

    Channels that open in minutes and interpret into many languages at once. For recurring meetings, short-notice events and tight budgets.

  • Hybrid

    Combine both at one event: the main language pair with interpreters, other languages with AI. Listeners join every channel with the same QR code, whichever mode runs it.

Sample event planFloor language: English
ChannelModeNote
EN → TRProfessional interpreter2 interpreters, taking turns
EN → ARAIAudio + captions
EN → RUAIAudio + captions
EN → DEAICaptions only

Four channels, one QR code. Interpreters can also supervise the AI channels live.

AI mode fits

  • Recurring meetings, webinars and internal events
  • Many languages at once on a limited budget
  • Short notice, when no interpreters are available
  • Captions and transcripts in every language

Professional interpreters are recommended for

  • Diplomatic, legal and medical settings
  • Negotiations where nuance carries risk
  • Heavy jargon or rapid, unscripted debate
  • The main language pair, when quality matters most

Built for live speech, not recorded video

Interpreting a live speaker is different from translating a file. Every part of simultane.ai is designed around speed, accuracy and the listener.

Remote interpreter console
Professional interpreters connect from anywhere, work in turns and hand over the channel to each other; a booth at the venue is optional.
Real-time AI interpreting
Natural-sounding interpreted voice that follows the speaker a second or two behind, like a human interpreter in a booth.
Live translated captions
Captions for every channel on listeners' phones, on the venue screen, or inside your meeting platform.
Event glossaries
Teach the interpreter speaker names, brand terms and industry vocabulary before the event starts.
Many channels at once
One speaker, any number of target languages, all running in parallel from a single audio source.
Automatic language switching
When a panel moves between languages, the floor language is detected and channels follow without anyone pressing a button.
Transcripts after the event
Download the full multilingual transcript to share, publish or archive once the session ends.
Private by design
Audio is processed for the session and not used to train models. Encrypted in transit and at rest.

AI channels a second and a half behind the speaker

Booth interpreters trail the speaker by a few seconds, the time it takes to grasp the meaning of a sentence. simultane.ai's AI channels keep that delay short by streaming audio, recognition, translation and voice synthesis together instead of waiting for each sentence to end.

Values in these charts are development targets. Actual delay depends on the language pair, audio quality and connection.

From a major summit to the weekly all-hands

At a major summit, give the main language pair to professional interpreters and the other languages to AI. For a weekly all-hands or a 40-minute webinar, AI alone may be enough.

  • ConferencesKeynotes and panels in every attendee's language, on their own phone.
  • WebinarsReach international audiences with live interpreted audio and captions.
  • Company meetingsAll-hands and town halls for teams spread across countries.
  • EducationLectures and training sessions for international students and staff.
  • Places of worshipServices followed by every member of a multilingual congregation.
  • Trade fairsProduct demos and stage talks for visitors from every market.

Questions about AI simultaneous interpreting

What is AI simultaneous interpreting?

AI simultaneous interpreting listens to a speaker and produces spoken interpretation and translated captions in other languages while the speaker is still talking, typically a second or two behind, the same way a human interpreter in a booth works.

Does simultane.ai provide professional interpreters too?

Yes. simultane.ai is not only AI interpreting. You can choose professional simultaneous interpreters for any language channel; they connect to the platform remotely or broadcast from a booth at the venue.

Can I combine interpreters and AI at the same event?

Yes. In hybrid mode you choose per language channel. For example, professional interpreters can cover English–Turkish while English–Arabic and English–Russian run on AI. Listeners reach every channel through the same QR code.

Do listeners need headsets or an app?

No. Listeners scan a QR code or open a link, choose their language and listen with their own earphones in the browser. Venues that already have interpreting receivers can connect them as an audio output.

Which platforms will simultane.ai work with?

simultane.ai is designed to take audio from a venue mixing desk, a laptop microphone or a meeting platform such as Zoom, Microsoft Teams or Google Meet, and to send interpreted channels back to listeners' phones, captions screens or the meeting itself.

When should I choose an interpreter and when AI?

We recommend professional interpreters for diplomatic, legal and medical content, wherever nuance carries risk, and for the event's main language pair. AI is a cost-effective choice for recurring meetings, webinars, short-notice events and when many languages are needed at once. You can also combine both at the same event.

When does simultane.ai launch?

simultane.ai is in development. Join the early access list to be invited to the pilot programme and receive launch pricing.
