yovoice is an open-source, local-first audio and music creation studio for macOS, Windows and Linux.
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.
Why yovoice?
- 🔒 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 v0.9.3. 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: Chat with DeepSeek, Qwen, Claude, OpenAI, or local Ollama to create and edit works end to end. Includes a native Model Context Protocol (MCP) server for Cursor and Claude Code.
Features
- 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.
- Transcribe and subtitles — turn audio or video into timed subtitle lines and export SRT / WebVTT, fill in a reference transcript automatically, or export aligned subtitles for a speech version.
- Music — write a style and lyrics with section markers, then generate songs or instrumentals with ACE-Step 1.5, or songs and score-based instrumentals with YuE2, or instrumental music and sound effects from an English description with Stable Audio 3; the playback page syncs lyrics to the vocals. Separate any song into six stems and mix them in the stem studio, or transcribe it to multi-instrument MIDI.
- 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 — the built-in assistant panel chats with DeepSeek, Qwen, Kimi, OpenAI, Anthropic, Ollama or any compatible API and acts on your works: it writes arrangements and lyrics, edits text, assigns voices and starts generation; 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.

Installation
Choose the package for your platform from the repository’s Releases tab or visit the official website.
| Platform | Package | Install |
|---|
| macOS 14+ · Apple Silicon | .dmg | Open the disk image and drag yovoice to Applications |
| Windows 10/11 · x64 | -setup.exe | Run the installer, then open yovoice from the Start menu |
| Windows 10/11 · x64 · NVIDIA GPU | -cuda12.4-setup.exe | Bundles the CUDA 12.4 runtime; works with older GPUs and drivers and uses the GPU from first launch |
| Windows 10/11 · x64 · NVIDIA GPU | -cuda13.3-setup.exe | Bundles the CUDA 13.3 runtime; needs a newer driver, smaller download |
| Linux · x64 (Debian/Ubuntu) | -linux-x64.deb | sudo apt install ./yovoice-<version>-linux-x64.deb, then open yovoice from the application menu |
| Linux · x64 (other distributions) | -linux-x64.tar.gz | Extract and run ./install.sh to add yovoice to the application menu for the current user |
The Windows installer downloads and installs WebView2 Runtime if needed. Models are downloaded inside the app; uninstalling preserves user data in ~/.yovoice.
On Linux the app needs WebKitGTK 4.1 (libwebkit2gtk-4.1-0 on Debian/Ubuntu, webkit2gtk4.1 on Fedora, webkit2gtk-4.1 on Arch); the .deb installs it automatically. Linux runs on the CPU out of the box, and a Vulkan GPU runtime can be downloaded in Settings → Inference engine. The Linux app doesn't update itself yet; download new versions from Releases.
