Hi, I noticed that **Gemini 3.5 Transcribe Live** is now available in LiveKit Agent Builder, but **Bulgarian (`bg-BG`)** is missing from the language dropdown. Google officially supports Bulgarian for this model. Are you planning to add it in the near future? Thanks! ---

It looks like Google list Bulgarian as experimental at [Gemini 3.5 Transcribe  |  Gemini Enterprise Agent Platform  |  Google Cloud Documentation](https://docs.cloud.google.com/gemini-enterprise-agent-platform/models/gemini/3-5-transcribe#supported-languages) which I guess is why we don’t claim support for it through LiveKit, however you can still specify the language code and it will be passed through to the model: ```python stt=inference.STT( model="google/gemini-3.5-transcribe-live", extra_kwargs={"language_codes": ["bg-BG"]}, ), ``` I know you were asking about Agent Builder, but this isn’t possible through Agent Builder, you would need to download the code and make the modification manually, as described here: > **[Convert to code - Agent Builder | LiveKit Documentation](https://docs.livekit.io/agents/start/builder/#convert-to-code)** > > The LiveKit Agent Builder lets you prototype and deploy simple voice agents through your browser, without writing any code.

Can’t we change the output code directly in the platform itself? I can see that there is a source code output window in read only mode. ---

Unfortunately Agent Builder doesn’t allow you to modify the code, so you would have to: - Download the code - Make the modification - Test the change (the easiest way to do this is to install the LiveKit [CLI](https://docs.livekit.io/intro/basics/cli/) and run `lk agent console` from inside the downloaded folder) - Deploy your changed agent (the easiest way to do this is to delete the existing cloud agent created with Builder, and run `lk agent create` from inside the downloaded folder) ---

Ok, thanks for your help! ---

So we tried this with both Bulgarian and English and it’s not working. STT stays empty for some reason and the agent doesn’t get the transcripts at all. ![viber_image_2026-09-28_20-21-05-779](https://us1.discourse-cdn.com/flex001/uploads/livekit2/original/2X/5/536f6f1bc69a21595a8c43ba196899bc49d7bc0e.jpeg) ![viber_image_2026-09-28_20-20-52-499](https://us1.discourse-cdn.com/flex001/uploads/livekit2/original/2X/0/056f867ff631c40a9da3653e13d61ae306118127.jpeg) ![viber_image_2026-09-28_20-20-31-380](https://us1.discourse-cdn.com/flex001/uploads/livekit2/original/2X/9/9a9e72ada728f49e37af0d8a84787845493dfcd9.jpeg) ---

[agent.py](https://community.livekit.io/uploads/short-url/ss6XAy7Lyw2gVu6IceiiprHuoyp.py) (8.5 KB) Maybe try the attached? This was what I created yesterday based on [GitHub - livekit-examples/agent-starter-python: A complete voice AI starter for LiveKit Agents with Python. · GitHub](https://github.com/livekit-examples/agent-starter-python) . You can clone that, replace the `agent.py` and run `lk agent dev`. You should then get the following: ![Screenshot 2026-09-29 at 13.02.13](https://us1.discourse-cdn.com/flex001/uploads/livekit2/original/2X/1/147b8b98b31033bf19054b86af75a872ec33ba9c.png) ---
