Using ElevenLabs in Electron Desktop Apps

Description and use

This guide demonstrates integrating ElevenLabs TTS into an Electron app via a main‑process service wrapper and an IPC bridge for secure API access.

Problem

Adding high‑quality, low‑latency text‑to‑speech to an Electron app is difficult due to poor voice quality, latency, and complex API authentication.

Outcome

The workflow enables an Electron app to synthesize realistic speech in a few lines of code, keeping the API key secure in the main process and providing low‑latency audio playback.

Workflow

• 1. Ensure Node ≥14, Electron ≥22, and obtain an ElevenLabs API key.
• 2. Store the key in an environment variable ELEVANLABS_API_KEY.
• 3. Install dependencies: node-fetch@2 and fs-extra.
• 4. Create src/elevenLabsService.js with a synthesize function that POSTs to ElevenLabs, streams audio to a temp file, and returns the file path.
• 5. Expose the service via context‑bridge (window.elevenLabs) in the main process.
• 6. In the renderer, call window.elevenLabs.synthesize(text, voiceId) and play the returned audio file.

Evidence

ElevenLabs cuts through that noise with ultra‑realistic, low‑latency speech synthesis and a simple REST API that fits right into the Node.js ecosystem.

Source

Store the key in an environment variable (ELEVANLABS_API_KEY) and never commit it to source control.

Source

Create src/elevenLabsService.js: ... async function synthesize(text, voiceId = 'EXAVITQu4vr4xnSDxMaL') ...
