Queue: n8n community node for Deepgram (STT, TTS, Audio Intelligence) #53

Integration: n8n Community Node

Origin

Requested in #25: "An n8n community node package (n8n-nodes-deepgram) that exposes Deepgram's core APIs — transcription (pre-recorded and streaming), text-to-speech, and audio intelligence — as drag-and-drop nodes in n8n workflow automations."

What this should show

Build an n8n community node package (n8n-nodes-deepgram) in TypeScript using the n8n node framework. The package should include:

1. Credential type — API key-based auth for Deepgram, with key validation
2. Transcription node — Accept audio file or URL input, call Deepgram pre-recorded STT, return transcript
3. TTS node — Accept text input, call Deepgram Aura TTS, output audio
4. Audio Intelligence node — At least one intelligence feature (summarization, topics, or sentiment) applied to a transcript
5. Example workflow JSON — A ready-to-import n8n workflow demonstrating the nodes

The package should be structured for publishing to the n8n community node registry. Include a clear README with setup instructions (clone, add API key, run).

Credentials likely needed

• DEEPGRAM_API_KEY

Reference

• n8n community node docs: https://docs.n8n.io/integrations/creating-nodes/
• n8n has 50k+ GitHub stars; native Deepgram nodes would improve discoverability
