yovoice is an open-source, local-first audio and music creation studio for macOS and Windows.

Turn text into expressive speech, natural cloned voices, complete vocal songs, and multi-track scores right on your machine. Featuring zero-shot voice cloning, emotional performance controls, AI music generation with lyrics, and General MIDI score arranging—all running 100% locally with zero cloud API calls, zero per-character fees, and zero Python environment headaches.

• 🔒 100% Local Privacy: Runs entirely on your local GPU/CPU. Your manuscripts, reference voices, and creations never leave your computer.
• 💸 Zero Recurring Fees: Say goodbye to per-character/per-minute meters and expensive cloud voice/music subscriptions.
• ⚡ Native C++ Performance (No Python Hell): Powered by audio.cpp v0.9.1. Ships with bundled Windows CUDA 12.4/13.3 runtimes and native macOS Metal support. Double-click and create—no Conda or PyTorch conflicts.
• 🎛️ Creator Workstation: Multi-take versioning for side-by-side comparison, waveform trimming, timeline scrolling, and clean stems/MIDI export.
• 🤖 MCP & AI Agent Ecosystem: Connect DeepSeek, Qwen, Claude, OpenAI, or local Ollama to write scores and lyrics in seconds. Includes a native Model Context Protocol (MCP) server for Cursor and Claude Code.

• Speech, voice design and cloning — clone a reference voice, design a voice from a description, adjust emotion and delivery, and edit takes on a timeline.
• Story dubbing — import text or subtitle files, assign a character to each line, and generate line by line.
• Music — write a style and lyrics with section markers, then generate songs or instrumentals with ACE-Step 1.5, or vocal songs with YuE2; the playback page syncs lyrics to the vocals.
• Score — write parts by bar and beat, import MIDI or let an Agent compose, render with a General MIDI sound font, and export MIDI and stems. See Score.
• Optional AI service — let DeepSeek, Qwen, Kimi, OpenAI, Anthropic, Ollama or any compatible API write arrangements and lyrics; keys stay on this computer. See AI service.
• 12 interface languages — English, 简体中文, 繁體中文, 日本語, 한국어, Español, Français, Deutsch, Português (Brasil), Русский, Italiano and Tiếng Việt; switch anytime in Settings, no restart needed.

All models are downloaded inside the App or with the CLI. See model selection for file sizes, hardware requirements, inputs and examples. OmniVoice, YuE2 and Breeze TTS 2 weights are restricted to non-commercial use.

Choose the package for your platform from the repository’s Releases tab or visit the official website.

The Windows installer downloads and installs WebView2 Runtime if needed. Models are downloaded inside the app; uninstalling preserves user data in ~/.yovoice.

Check for updates from the app menu on macOS or Windows. Updates are also checked and downloaded in the background; restart to install when ready. Windows updates download only the app (-update.exe) and keep the installed runtime; when a release recommends a newer runtime you can upgrade it in Settings → Inference engine.

1. Set up a model. Download a model in Settings (e.g. Kokoro-82M for fast narration, or VoxCPM2 for cloning).
2. Create a project. Choose Story dubbing, Speech generation, Music, or Score.
3. Add content. Enter text, lyrics, or notes, then pick a character and adjust style.
4. Generate audio. Select Generate, then preview, compare takes, edit, and export.

Give your agent the yovoice Skill link and ask it to install the Skill and set up the local CLI, engine, and model:

Install this Skill and set up yovoice for local speech generation: https://github.com/leemysw/yovoice/tree/main/skills/yovoice

Then describe what you want:

Read narration.txt using voice.wav as the reference voice, with a calm delivery, and save it as narration.wav.

The agent runs the standalone CLI without opening the desktop app. See the CLI guide for details.

Run yovoice serve to provide an authenticated HTTP API and MCP inference service for other machines. See the API / MCP deployment guide for deployment and client examples.
