You're hosting a business meeting, town hall, or webinar on Zoom, but not everyone joining speaks the same language. Know the feeling? That's where live translation solutions like remote simultaneous interpretation, captions, subtitles and AI speech to speech translation can make the impossible possible.
Zoom offers some built-in language capability but, as many have found out, not the serious capability needed for serious events. Interprefy offers the same high-function multi-lingual support for Zoom as it does for other meeting and conferencing platforms.
Language interpretation, Zoom integration, and managed interpretation services ensure a seamless experience for all parties, to even the most complex set-ups, like for example The White House Summit on Climate Change.
But before we jump ahead of ourselves, let's look at the Zoom translation options available today.
Hosts of multilingual Zoom meetings and webinars have essentially three types of translation technology available to them:
Zoom's interpretation feature allows you to connect interpreters to your meetings. Meeting hosts have to activate the interpretation feature when scheduling the meeting and select the audio language channels they want to make available during the meeting.
Once scheduled, meeting hosts will need to find the right interpreters and invite them to the meeting in their designated roles. Interprefy does this for you.
Zoom provides nine default languages for interpretation: English, Spanish, French, German, Portuguese, Japanese, Russian, Korean and Chinese. In addition to these, you can add as many custom languages to your list as you need.
However, during any single meeting or webinar, you can only use five custom languages alongside the nine default ones. To use up to 25 custom languages in a meeting, you need to contact Zoom Support.
When the meeting starts, the host starts interpretation, and each interpreter broadcasts into the audio channel for their language. Interpreters can switch between the main audio channel and their assigned language, and can also listen to another interpreter’s channel instead of the original speaker. Zoom calls this interpretation relay.
In order to use the language interpretation feature in Zoom, you will need a Zoom Pro, Business, Education or Enterprise account. First, turn on language interpretation in your Zoom settings:
Sign in to the Zoom web portal;
In the top-right corner, click your profile picture or initials, then click Settings;
Click the Meeting tab;
Under In Meeting (Advanced), turn on the Language Interpretation toggle.
Then, when you schedule your meeting:
In the Zoom web portal, click Meetings, then Schedule a Meeting;
Next to Meeting ID, select Generate Automatically. Language interpretation doesn’t work with a Personal Meeting ID;
Next to Interpretation, select Enable language interpretation;
Add your interpreters’ email addresses and the languages they will interpret, then click Save.
Once the interpretation in your required languages is set up, you will see an audio channel for each language in your Zoom meeting. Participants simply click Interpretation (the globe icon) in the meeting controls and select their preferred language. They can also click Mute Original Audio to hear only the interpreted language. This works in the Zoom desktop app, the mobile app and the web app.
While Zoom's built-in interpretation feature is a popular choice for small, simple meetings, it comes with a few challenges for both the interpreter and the meeting organiser.
Initially, Zoom wasn't built for interpretation and lacks the specialized tools that professional interpreters require.
As with any resource, the difference a sub-optimal working environment makes is that the specialist, professional interpreters, who represent a significant cost, will not deliver as good a service as they should. A lot of the missing features relate to interpreters working together:
The success of multilingual Zoom meetings and larger events depends heavily on three key factors: having the right interpreters available; using reliable and specialized technology; and working with an experienced interpretation partner who can assist with setup, interpreter onboarding, and technical support — both general and language-specific — throughout the session.
However, organisers should also be aware of several built-in limitations within Zoom’s interpretation feature:
Language Limits: While Zoom offers 9 default languages, organisers can only use up to 5 custom languages per meeting, or up to 25 by contacting Zoom Support. This can be restrictive for events requiring broader language support.
Interpreter Constraints: Interpreters can only broadcast to one language channel at a time, and they must join from the Zoom desktop app using computer audio. Phone dial-in isn’t supported for interpreters.
Platform Limitations: Interpretation can only be set up and managed from the Zoom desktop app. Participants on the mobile app or web app can listen to interpretation channels, but can’t manage interpretation, and it can’t be used in instant meetings or with a Personal Meeting ID.
A professional end-to-end remote interpretation provider like Interprefy can help by setting you up for success and making your Zoom event a seamless and rewarding experience for all involved.
Interprefy can:
Working with a dedicated platform like Interprefy also means better conditions for the interpreters themselves:
With Interprefy for Zoom, both meeting participants and interpreters can enjoy a range of benefits, and focus solely on the content of their Zoom meeting or webinar, while Interprefy manages the rest.
The Interprefy real-time interpretation solution can be integrated with Zoom to stream the video and audio from the Zoom meeting to our interpreter soft console and feed the interpreters’ translated rendition of the speech back into Zoom into the respective interpretation audio channels.
Watch how Interprefy language interpretation for Zoom works:
Working with Interprefy, you can tap into a global pool of interpreting talent. Interprefy partners with leading Language Service Providers across the globe to source, train and onboard more than 6,000 vetted professional interpreters. That means you can find the best fit interpreters for even the rarest language combinations and with the expertise in your subject area.
For Zoom meetings without language interpretation, meeting organisers can choose to activate closed captioning in multiple languages, providing participants with live transcription of what's being said. Captions can be a game changer, providing a range of benefits, from better accessibility, to better knowledge retention.
Zoom meeting hosts can enable automatic live transcription / captioning for a meeting, or assign participants to manually type captions (CART). If a participant joins the meeting and closed captioning is available for that meeting, the captions can be viewed on the display.
Yes, In October 2021 Zoom made automated captions, also known as live transcription, a feature available to all Zoom accounts.
Zoom meeting hosts have two captioning options available:
If you are required to use speech-to-text support for any compliance or accessibility needs in your meetings and webinars, Zoom themselves recommend using an external third-party service able to guarantee specific accuracy.
Zoom’s automated captions provide a live transcription of what’s being said, helping make meetings more accessible for people who are deaf or hard of hearing. The setting is turned on by default for paid Zoom accounts, and account owners and admins can switch it on or off for the whole account or for groups of users.
To check or change the setting for the meetings and webinars you host:
If the setting is greyed out, your Zoom admin has locked it at account or group level.
You can also turn on Automated captions on device, which processes captions on the participant’s own computer. This helps when the internet connection or audio quality is poor, and it requires the Zoom Workplace desktop app 6.5.3 or later.
When activated by the meeting host, participants can click on Show Captions (CC).
Automated captions will begin generating and appearing in the meeting window.
Zoom can automatically generate live captions for speech in the following 49 languages and dialects: Afrikaans, Arabic, Arabic (Gulf), Bengali, Cantonese, Catalan, Chinese (Simplified), Chinese (Traditional), Croatian, Czech, Danish, Dutch, English, Estonian, Finnish, French (Canada), French (France), Galician, German, German (Switzerland), Greek, Hebrew, Hindi, Hungarian, Indonesian, Italian, Japanese, Korean, Latvian, Malay, Norwegian, Persian, Polish, Portuguese, Romanian, Russian, Serbian, Slovak, Somali, Spanish, Swedish, Tagalog, Tamil, Telugu, Thai, Turkish, Ukrainian, Vietnamese, Zulu.
A recent study reports 90-95% captions accuracy. The problem with captions accuracy measurement however is that it often does not take into consideration the seriousness of mistakes. Zoom does not offer a dictionary tool, or any preparation capability to pre-populate the system with names, acronyms, or context-specific terms that you need to be sure will be accurately transcribed.

Yes, Zoom-translated captions allow users to have the speech automatically real-time translated and access captions in another language. For example, if a meeting participant is speaking in English, other participants can view Italian, German, or Japanese captions.
Which caption languages are available during a meeting or webinar are determined by the host in the web settings before the live session, but participants can enable captions and switch languages themselves.
Translated captions are included in Zoom Workplace Business Plus, Enterprise Essentials, Enterprise Plus and Enterprise Premier plans, or available as a paid add-on. Some accounts in regulated industries, such as healthcare and higher education, may not have access.
Zoom’s multilingual toolkit includes AI live translated captions in only up to 36 languages, including Arabic, Cantonese, Chinese (Traditional), Chinese (Simplified), Czech, Danish, Dutch, English, Estonian, Finnish, French (Canada), French (France), German, Hebrew, Hindi, Hungarian, Indonesian, Italian, Japanese, Korean, Malay, Norwegian, Persian, Polish, Portuguese, Romanian, Russian, Spanish, Swedish, Tagalog, Tamil, Telugu, Thai, Turkish, Ukrainian, Vietnamese.
Dialects of one another are not currently supported for translation, such as translating between French (France) and French (Canada). Catalan and Welsh are supported when translating from one of the fully supported languages above, but cannot be the source language. Bengali and Greek can only be translated to and from a limited set of languages.
While a great first step in helping Zoom meeting organisers overcome accessibility and language barriers, Zoom's automatic captioning comes with a few limitations:
With Interprefy’s expanded captioning language support including dictionaries that extend into 80+ languages. Using Interprefy, Zoom sessions can now be streamed with real-time captions in additional languages, as well as translations to multiple languages.
Using Interprefy-powered captions and subtitles next time you host a Zoom event could mean the difference between merely having an audience and having a highly engaged audience.
Captions let participants read a meeting in their language. AI speech translation lets them listen to it. Zoom now offers a native option, and Interprefy Agent adds broader language coverage across platforms.
In July 2026, Zoom launched Voice Translator, its own AI speech-to-speech translation for meetings. Each participant chooses the language they speak and the language they want to hear, and listens to a synthetic translated voice alongside or instead of the original speaker.
Before relying on it, it’s worth knowing that:

If you need more languages than Zoom covers, Interprefy Agent steps in. Acting as a secure virtual participant, Interprefy Agent streams your meeting audio to Interprefy’s platform, where AI produces live voice translation and captions in more than 80 languages, with Speaker Labels showing who is speaking. Attendees simply follow the secure link or QR code the Agent shares in the chat to listen or read in their preferred language on any device. With no extra software or complex routing, hosts can scale multilingual voice translation and richer caption support across Zoom, Microsoft Teams, Google Meet and Webex.
Interprefy Agent works with pre-scheduled Zoom meetings. It isn’t available for Personal Meeting Rooms, ad-hoc meetings, registration-required meetings and webinars, or breakout rooms. For those, and for professional interpreters, Interprefy’s integration and web and mobile apps are the better fit.
