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
