[Suggestion] n8n community node for Deepgram audio transcription and intelligence analysis (TypeScript)

[deepgram-robot]

What to build

An n8n community node (n8n-nodes-deepgram) that exposes Deepgram STT, TTS, and Audio Intelligence as native n8n workflow nodes, enabling no-code/low-code audio processing pipelines.

Why this matters

n8n is one of the fastest-growing workflow automation platforms, and developers building audio processing pipelines need a native Deepgram node to connect transcription and analysis with their existing workflows (CRM updates, Slack notifications, database writes, email triggers). Multiple competing STT providers already have n8n presence, but Deepgram — with the broadest feature set (STT + TTS + Audio Intelligence) — is absent. This blocks no-code developers from choosing Deepgram for automated audio workflows.

Suggested scope

• Language: TypeScript (n8n node SDK)
• Nodes: Deepgram Transcribe (pre-recorded STT with model selection), Deepgram Listen (trigger node for streaming), Deepgram Speak (TTS), Deepgram Analyze (Audio Intelligence — sentiment, topics, entities, summarization)
• Credentials: Deepgram API key credential type with connection test
• n8n version: Compatible with n8n v1.x community node API
• Package: Publishable to npm as n8n-nodes-deepgram
• Complexity: Medium — follow n8n community node starter template

Acceptance criteria

• Runnable with minimal setup (clone, add API key, run)
• README explains the pattern clearly
• Uses current SDK version
• Implements at least Transcribe and Speak nodes with credential management
• Includes example workflow JSON for common patterns (e.g., "transcribe uploaded audio → extract topics → post to Slack")
• Published or publishable to npm as an n8n community node
• Works with n8n self-hosted and n8n Cloud
