Gong identifies the language that was spoken on a call. If the language is incorrectly identified, or if multiple languages were spoken in a call and you want the transcript to reflect a different language than the one reflected in the transcript, reprocess the call from the call page.
To do this, click in the top right corner, select Transcribe call in correct language and select which language you want the transcript to be in.
Some things to keep in mind:
Reprocessing can take up to 1 hour, during which time the call will be unavailable.
Transcribing the call in a different language is not translation. For select languages, it is possible to translate the transcript into English. For more, see this.
After a call is reprocessed, Gong reapplies its analysis to the call, and related insights will be based on the new language.
If you see that Gong is consistently misidentifying your call languages, contact Gong support
