I need Soniox STT in javascript ?

Thanks for reaching out, Sidharth. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.

I dont want a separate python and JS backend. I want to use Livekit JS SDK only.

Thanks — I hear you: you want to use only the LiveKit JavaScript SDK (no separate Python backend) and have Soniox STT in JS. Short answer: Soniox STT is not available as a LiveKit JS plugin. You cannot run the Soniox LiveKit plugin inside a pure-JS-only LiveKit agent. Options you can take while staying JS-only: • Call Soniox’s REST API directly from your Node.js app (send audio files or chunks over HTTP). I can provide a Node.js example for that. • Use a different STT provider that has official Node/JS support in the LiveKit ecosystem (examples: Deepgram or OpenAI). I can show how to wire one of those into a LiveKit JS flow. Which would you like: • A Node.js example calling Soniox REST for offline/HTTP transcription, or • A LiveKit JS example using Deepgram or OpenAI for real-time/streaming transcription?

So If I create a separate Soniox implementation can I pass the trasncription to livekit and it can pick up the flow from there?

Thanks — I hear you want to implement Soniox separately and have LiveKit "pick up" the flow. Short answer: you cannot inject external Soniox transcriptions into a LiveKit AgentSession to resume the agent's internal STT→LLM→TTS pipeline. What you can do (pick one and I’ll help next): • Send Soniox transcripts into the LiveKit room as text (e.g., sendText on topic

lk.transcription

) for UI display or client-side handling. This does not trigger agent logic. • Run a minimal LiveKit agent backend that uses the Soniox plugin—this is the supported way to keep the full agent workflow (STT → LLM → TTS) intact. • Keep everything JS-only and use a JS-supported STT provider (Deepgram or OpenAI) so you can both transcribe and integrate with LiveKit without a Python backend. Which option do you want to proceed with? If you choose the first, I can show a Node.js example to send transcripts into the room; if the second, I can outline the minimal agent setup; if the third, I can provide a LiveKit + Deepgram/OpenAI JS example.
