Call language

The bot reads Meet's captions, not audio. Set the caption language wrong and it doesn't go quiet — it becomes confidently wrong.

Your agent doesn't transcribe audio. It reads Google Meet's live captions, which means

Meet's caption language decides what the agent hears.

google-meet-provider.js:2995

Set it wrong and the failure is quiet: Meet turns perfectly good speech into phonetic

gibberish, and the agent answers the gibberish. It doesn't go silent — it becomes confidently

wrong, and nobody notices until someone reads the transcript.

This is the most common way a call goes wrong, and it never announces itself.

Set it before you talk

Caption language is per participant in Meet — there is no host-level control, so the

setting that matters is the one on the bot's own view, not yours. An agent can set it

directly; the tool walks Meet's own settings dialog.

server.js:2308

Use a BCP-47 tag: en-US, de-DE, fr-FR, es-ES, pt-BR, ja-JP.

If it seems deaf

SymptomWhat it usually is
Answers nothing at allCaptions are off. No captions, no hearing.
Answers the wrong question, fluentlyCaption language mismatch — it heard different words
Went deaf after being admitted lateIt sat in the lobby too long and burned its caption retries
Missed a stretch, then recoveredThe caption pane scrolled past the turn it was holding

The last two are known app bugs, not you doing something wrong.
