--- 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.** ![yovoice creation workspace — browser preview](docs/images/yovoice-workspace.png) --- ## 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](https://github.com/0xShug0/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. --- ## Features - **Voice and expression** — use a reference voice, match a reference performance, adjust emotions, or describe the delivery in words. - **A complete audio workflow** — import or record reference audio, trim clips, preview speech, and export your work. - **Voice design and cloning** — VoxCPM2 offers text-guided voice design, controllable cloning, and transcript-assisted cloning with automatic multilingual handling, and 48 kHz output. - **Music generation** — describe a style, write lyrics with section markers, and generate full songs or instrumentals with ACE-Step 1.5; every take is kept as a version to compare. - **Score** — write each part by bar and beat, import MIDI or let an Agent write the score, then render it with a General MIDI sound font and a role-based mix; results are exactly repeatable and export to MIDI and stems. See [Score](docs/score.md). - **Optional AI service** — connect DeepSeek, Qwen, Kimi, OpenAI, Anthropic, Ollama or any compatible API to let AI write arrangements and lyrics; keys stay on this computer. See [AI service](docs/ai.md). - **Local models** — run IndexTTS 2.0 / 2.5, VoxCPM2, OmniVoice, Qwen3-TTS, Breeze TTS 2 and Kokoro through audio.cpp, with resumable, verified model downloads. - **Hardware acceleration** — Metal on Apple Silicon; CPU, NVIDIA CUDA, and experimental Vulkan on Windows. - **Agent Skill & MCP** — ask your AI agent to set up local speech generation and create voiceovers from text and reference audio. --- ## Hardware & VRAM Quick Guide | Use Case | Recommended Hardware | Recommended Models | | --- | --- | --- | | 🟢 **Lightweight & Blazing Fast** | Any CPU / 4 GB+ RAM | **Kokoro-82M** (only 189 MB Q8, millisecond latency, runs great on CPU) | | 🟡 **High-Fidelity Voice Cloning** | 4 GB – 6 GB VRAM / 8 GB+ Apple Silicon | **VoxCPM2** (2B, 48 kHz), **IndexTTS 2.0/2.5**, **Qwen3-TTS** | | 🔴 **Full Song & Music Generation** | 12 GB+ VRAM / 16 GB+ Apple Silicon | **ACE-Step 1.5 Turbo** (BF16, 10 GB), **YuE2 3B** | --- ## Supported Models | Model | Parameters | Model file size by precision | Core capabilities | | --- | --- | --- | --- | | IndexTTS 2.0 | — | Q8 · 3.63 GB

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. ![Install yovoice on macOS](docs/images/yovoice-macos-install.png) --- ## 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](https://github.com/leemysw/yovoice/tree/main/skills/yovoice) 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](docs/cli.md) for details. --- Run `yovoice serve` to provide an authenticated HTTP API and MCP inference service for other machines. See the [API / MCP deployment guide](docs/api.md) for deployment and client examples. ## Development ```sh make install make app-run ``` See the [development guide](docs/development.md) for prerequisites. It also covers browser preview, tests, and project structure. --- ## Contributing Bug reports, feature suggestions, and pull requests are welcome. Include your platform, model, and steps to reproduce when reporting a problem. Run `make check` before submitting code changes. --- ## Acknowledgements - [audio.cpp](https://github.com/0xShug0/audio.cpp) by ShugoAI — the local audio inference engine. - [VoxCPM](https://github.com/OpenBMB/VoxCPM) — voice design and cloning models, licensed under Apache-2.0. - [IndexTTS](https://github.com/index-tts/index-tts) — the speech synthesis models behind yovoice. - [OmniVoice](https://github.com/k2-fsa/OmniVoice) — voice design and cloning models. - [Qwen3-TTS](https://github.com/QwenLM/Qwen3-TTS) — voice cloning, built-in voices, and text-guided voice design. - [ACE-Step](https://github.com/ace-step/ACE-Step-1.5) — music generation from style prompts and lyrics. - [go-meltysynth](https://github.com/sinshu/go-meltysynth), [MuseScore General](https://musescore.org/en/handbook/3/soundfonts-and-sfz-files#gm_soundfonts), [GeneralUser GS](https://www.schristiancollins.com/generaluser) and SGM-V2.01 by David Shan — the SoundFont synthesizer and sound fonts behind score rendering. - Kokoro — lightweight speech synthesis with built-in voices: [Kokoro-82M](https://huggingface.co/hexgrad/Kokoro-82M) and [Kokoro-82M-v1.1-zh](https://huggingface.co/hexgrad/Kokoro-82M-v1.1-zh). --- ## Star History
