yovoice

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.
• 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.
• 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.

Supported Models

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; Stable Audio 3 is free below USD 1M annual revenue under the Stability AI Community License.

Installation

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.

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.

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.

Quick Start

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.

CLI & Agent Skill

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.

Development

make install
make app-run

See the development guide for prerequisites. It also covers browser preview, tests, and project structure. For how the processes and packages fit together, see Architecture.
