Browser-first Piper TTS workspace

Test voices locally, preview output quickly, and export WAV files from a clean local session.

Why this project exists

Voice Desk TTS is a focused web app for people who want to:

• run Piper voices locally in the browser
• compare voices quickly without setting up a full backend
• keep a lightweight generation history
• sync against the official Piper voice catalog
• train or fine-tune voices through the bundled Colab workflow when needed

This repository is intentionally narrower than a general speech lab. It is designed around browser TTS workflows first.

Highlights

• React + Vite TTS workspace with a compact, tool-like UI
• Piper ONNX inference in the browser through Web Workers
• Local model discovery for Vietnamese, English, and Indonesian
• Official Piper catalog normalization into a single JSON index
• Stable vs experimental model labeling for browser realism
• Recent render archive stored locally for quick reuse
• Bundled Colab and training guides for teams that want one workspace

What makes it useful

• compact React + Vite TTS workspace
• browser inference through Web Workers
• local model folders plus official Piper catalog support
• recent render archive for reuse and quick regression checks
• Colab-first training workflow for exporting new voices back into the app
