When the meeting or webinar starts, the host can start the interpretation feature, which will give the interpreters access to their own audio channels. 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.  

Cloud recordings of interpretation sessions will only record the original audio of the meeting or webinar, not the translations. Local recordings of interpretation sessions will record any audio that the person recording can hear, but not multiple audio channels. "
