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 10 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

1. In n8n, go to Settings → Community Nodes → Install
2. Enter n8n-nodes-leanvox
3. Add a LeanVox API credential with your API key
4. 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:

1. Add a Manual Trigger or Webhook node
2. Add the LeanVox node
3. Set Resource to Speech, Operation to Generate
4. Pick a model: standard for speed, pro for voice quality, max for custom voice instructions
5. Set a voice ID (e.g. podcast_conversational_female for Pro)
6. 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.
