Users that would like to include interpreters in their meetings or webinars now have the ability to enable language interpretation. This allows the host to designate participants as interpreters on the web portal or during a Zoom session. 

When the meeting or webinar starts, the host can start the interpretation feature, which will allow the interpreters to provide their own audio channels for the language they are translating to. Attendees can select an audio channel to hear their language of choice. Attendees will hear the translated audio and can choose if they want to hear the original audio at a lower volume.  

The languages currently supported are: English, Chinese, Japanese, German, French, Russian, Portuguese, Spanish, Korean

You will need to enable it first under your account setting settings here.

Add  other languages if you need to.


The next time you schedule a meeting, select Enable Interpretation and invite interpreters.
Add  interpreter, if there are more.
