Automate Voice with LeanVox + n8n: Our Community Node is Live

If you use n8n for workflow automation, you can now add voice AI to any workflow. Our community node is live on npm.

n8n-nodes-leanvox

Install it from Settings → Community Nodes in your n8n instance. That's it.

#What Can You Build?

The node covers the full LeanVox API — text-to-speech, speech-to-text, and multi-speaker dialogue. Here are some workflows that take minutes to set up:

Blog to Podcast

RSS feed triggers → extract article text → LeanVox Generate Speech → upload MP3 to S3 or your podcast host. Every new blog post automatically becomes an audio version.

Meeting Transcriber

Webhook receives recording → LeanVox Transcribe (with diarization + summary) → post summary to Slack. Know who said what without listening to the whole meeting.

Multilingual Voicemail

Form submission → LeanVox Generate Speech in 8 Standard languages or 23 Pro languages → email each version. One form, global reach.

Content Moderation Pipeline

Audio upload webhook → LeanVox Transcribe → scan transcript for flagged keywords → alert on Slack or email. Automate audio review at scale.

#Available Operations

The node gives you 8 operations across 4 resources:

Generate Speech — convert text to audio using Standard (fast), Pro (238 curated voices), or Max (instruction-based voice design)
Generate Speech (Async) — same thing, but for long text. Kicks off a background job so your workflow doesn't time out
Check Job — poll an async job until it's done
Dialogue — multi-speaker conversations. Pass an array of lines with different voices
Transcribe — audio → text, with optional speaker diarization and AI summary
List Voices — get all available voice IDs
List Curated Voices — browse our 238 curated voices with preview audio
Check Balance — see your remaining credits

#Setup in 60 Seconds

In n8n, go to Settings → Community Nodes → Install
Enter n8n-nodes-leanvox
Add a LeanVox API credential with your API key
Drag the LeanVox node into any workflow

That's the whole setup. No Docker config, no environment variables, no SDK installation.

#Example: Text to Speech in a Workflow

Here's the simplest possible workflow — take text input and generate audio:

Add a Manual Trigger or Webhook node
Add the LeanVox node
Set Resource to Speech, Operation to Generate
Pick a model: standard for speed, pro for voice quality, max for custom voice instructions
Set a voice ID (e.g. podcast_conversational_female for Pro)
Pass your text — done

The node returns JSON with an audio_url you can pass to any downstream node — upload to S3, send via email, post to Slack, whatever your workflow needs.

#Async for Long Content

For longer text (articles, chapters, scripts), use Generate Speech (Async). It queues a background job and returns a job_id. Chain it with the Check Job operation in a loop to poll until complete. No timeout issues, even for book-length content.

#Pricing

Same credits, same pricing as the API. Standard at $0.005/1K chars, Pro at $0.01/1K chars, Max at $0.03/1K chars. Transcription at $0.002/min. See full pricing.
