Create multi-voice podcasts with AI text-to-speech. Add segments, assign different voices to each, preview in real-time, and export as audio.

• Multi-segment editing — Add unlimited text segments
• Per-segment voices — Assign different voices to each segment
• Audio pre-generation — Generate audio clips before playback for consistency
• Audio caching — Generated clips are cached for instant replay
• Real-time preview — Play individual segments or the entire podcast
• Audio export — Download your podcast as a single WAV file
• Project management — Export/Import podcasts as JSON

example/podcast-1765734509668.wav

git clone https://github.com/microsoft/VibeVoice
cd VibeVoice

Copy the server script to your VibeVoice directory:

cp example/server.py /path/to/VibeVoice/demo/server.py

Run the server:

cd /path/to/VibeVoice
python demo/server.py --model microsoft/VibeVoice-Realtime-0.5B --device cuda --port 8880

The server will start at http://localhost:8880.

# Install dependencies
bun install   # or npm install

# Start development server
bun dev       # or npm run dev

Open http://localhost:5173 in your browser.

1. Add segments — Click "Add Segment" to create new text entries
2. Write content — Enter text for each segment
3. Select voices — Choose a voice from the dropdown for each segment
4. Generate audio — Click "Generate" on each segment to create the audio clip
5. Preview — Click "Play" on individual segments or "Play Podcast" for all

Each segment has a Generate / Regenerate button:

• Generate — Creates the audio clip for that segment (amber button)
• Regenerate — Re-creates the audio if you want a different take
• Generate All — Generates all missing audio clips at once
• Ready — Green indicator shows the segment has cached audio

Tip: Pre-generating audio ensures consistent playback. Each time you generate, the audio is cached and will play the same way every time — no more "I feel lucky" randomness!

• If a segment has cached audio, it plays instantly
• If not cached, it will generate first, then play
• The cache is invalidated when you change text or voice

• JSON — Save your project with "Export JSON" to continue editing later
• Audio — Click "Download Audio" to export the complete podcast
  • Uses cached audio where available (fast!)
  • Generates missing segments automatically

Click "Import" and select a previously saved JSON file to restore your project.

Check the example/ folder for sample podcast JSON files you can import.

The frontend connects to the API at http://localhost:8880/api. To change this, edit the API_BASE constant in src/App.tsx.

• Frontend: React + TypeScript + Vite + Tailwind CSS
• Backend: FastAPI + VibeVoice TTS
• Audio: REST API synthesis with client-side caching
