RTMS sends the same text Zoom is generating for the meeting’s automated captions, so the transcript language [follows the meeting’s spoken “Caption language”](https://support.zoom.com/hc/en/article?id=zm_kb&sysparm_article=KB0059762) (and Zoom’s auto-detection, [which can take ~10 seconds before it locks in](https://devforum.zoom.us/t/inquiries-about-multilingualism-in-rtms/137162)).

The host/admin must allow automated captions and can limit which languages are available; Zoom explicitly says “the availability of languages is determined by the host’s automated captioning settings” in both [host caption management](https://support.zoom.com/hc/en/article?id=zm_kb&sysparm_article=KB0062813) and [participant caption language selection](https://support.zoom.com/hc/en/article?id=zm_kb&sysparm_article=KB0059762). If the host restricts who can enable captions, participants have to use the built-in “Request captions” flow and the host approves it.

If captions are available, a participant can set “Caption language” from their Zoom client, but it [impacts all participants](https://support.zoom.com/hc/en/article?id=zm_kb&sysparm_article=KB0059762). An RTMS app can only suggest a “Default Source Language for Transcripts,” and Zoom notes auto-detection will override it after ~30 seconds ([RTMS changelog](https://developers.zoom.us/changelog/rtms/october-06-2025/)); for translated output, use Zoom’s [translated captions](https://support.zoom.com/hc/en/article?id=zm_kb&sysparm_article=KB0059081) or translate RTMS text yourself.

Hi @ariel1, Realtime Media Streams can set the default source language in `src_language`[in the media parameters](https://developers.zoom.us/docs/rtms/media-parameter-definition/#transcript). Here’s the [list of supported transcript languages](https://developers.zoom.us/docs/rtms/data-types/#rtms_transcript_language).

Today, this sets the default language the detection should start with. If the meeting participant starts speaking a new language, the transcript language could switch.

In our upcoming release in February, this parameter will now **always** determine the language and no longer rely on auto detection. Your app will select the language the app requested.
