How remote simultaneous interpreting works

Remote interpreting, or Remote Simultaneous Interpretation (RSI) allows conference interpreters to work from anywhere in the world through a cloud-based platform.

That means live real-time interpreting from vetted pro-interpreters can be added to any online meeting, hybrid conference, webinar, and beyond.

What is Remote Simultaneous Interpretation (RSI)?

Simultaneous interpretation is defined by ISO, the International Standards Organisation, as the process of rendering a spoken or signed message into another spoken or signed language, preserving the register and meaning of the source language. Add “remote” to the equation and it is possible for interpreters, speakers and participants to interact from anywhere on the planet.

How it works

Remote Simultaneous Interpretation (RSI) is the process of remotely translating speech from one language to another in real-time. It’s typically done through a cloud-based platform, meaning no lag, no equipment and no barriers.



A presenter speaks in one language. Their voice and image are streamed live to a remote interpreter, typically through a web browser on a laptop or desktop computer.

The interpreter hears and sees the speaker on their device. Using a quality headset and microphone, they translate the speaker's speech into another language, all in real-time.

The interpreter's speech is transmitted to a cloud-based Remote Simultaneous Interpretation platform from where it is then transmitted to the audience.

Attendees and delegates can connect to the RSI platform or to a third-party web conferencing platform via a computer or mobile device and see and hear the speaker in their language of choice. The audience can also access interpretation through traditional IR headsets if needed.

Remote interpreting explained

Simultaneous and conference interpreting hasn't changed much since 1945 – but we're on a mission to change that with. Simultaneous interpreting used to be an expensive and exclusive service that only large international and government organisations could afford.

RSI has democratised simultaneous interpretation by making it a service available for everybody: SMEs, associations and even NGOs.

How can our simultaneous interpretation services help?

Whether your event is happening in multiple locations simultaneously, or you require specialist interpreters with an in-depth knowledge of your industry, we’ve got it covered. 

The Interprefy platform is designed to be scalable and flexible, ensuring it can meet the specific needs of your event. Attendees and delegates can listen to content in the language of their choice while your interpreters work remotely.

In addition to our remote simultaneous interpretation platform, we can also help source conference-level interpreters, assist with technical set-up onsite and provide venue management support, as well as record your meeting or event.

Why use a remote simultaneous interpretation service?

Traditional interpretation is broken: it requires a lot of time and money to configure and manage, and interpreters are required on-site.

You have to clear floor space for interpretation booths, find and fly in interpreters, and set up a complex hardware system.

As a result, you spend a considerable amount of your budget on equipment, travel and accommodation for interpreters, that are limited in terms of availability and language/specialisation options.

Simultaneous Interpretation Mobile App

Remote simultaneous interpretation removes the need for equipment and interpreters to be on site.

This allows you to run events at short notice and with minimal infrastructure and, if necessary, entirely online.

And because events can be run remotely, you can increase the number of languages you offer as you no longer need to worry about flying rare-language interpreters over.

How RSI technology helps connect you to your audiences

Language, when you think about it, is the most important way we have of learning about each other, our universe and our place in it. It opens our minds to a world of ideas, all of which we share, shape and develop.

This is why multilingualism is so important for events and meetings in our increasingly interconnected world – it enables us to understand each other and better collaborate. Want to know what the sound delay between the speaker and the interpretation is with Inteprefy's RSI?
