DEDUPEDWho it is forDeveloper building an agent workflow that needs to speak or produce voiceovers without a paid API
The problemHosted speech APIs add cost, keys and data exposure to an agent pipeline.
The outcomeAn agent that calls your local VoiceStudio to produce audio files on request.
What you need first
- macOS, Windows or Linux desktop (Intel Mac runs the UI only and needs a remote backend)
- NVIDIA GPU (CUDA) or Apple Silicon (Metal) recommended; CPU-only works but is slower and needs about 5 GB free disk
- Git, Node.js 22+, Bun and Rust/Cargo only if building from source
- Speech models are downloaded on demand through the app; no paid keys or accounts required
Steps
- Install and run the app, and make sure a speech model is installed.
- Read docs/mcp.md and docs/speech-platform.md in the repo for the local API and MCP setup.
- Register the local MCP server in your agent's config using the details from those docs.
- Ask the agent to generate a short clip and confirm the audio file appears.
Prompt for your agent
Set up debpalash/VoiceStudio's local MCP server for this agent by following docs/mcp.md in the repo, then generate a short spoken clip of <text>. Verify the audio file exists and plays.
Caveat. The README only points to the MCP and API docs, so exact config keys and ports must come from those docs, not from guesses.

- Dub a video into another language with timed speech Feed a video to the dubbing workspace and get a translated voice track that lines up with the original timing.
- Run voice generation on an older laptop with no graphics card Use the CPU build to clone and generate voices on hardware without a dedicated GPU, trading speed for access.
- Turn a finished manuscript into an audiobook Use the audiobook workflow to render a long text into narrated audio with your chosen voice.
- Design a brand-new voice from a text description Describe the voice you want and generate it, with no reference recording needed.
