voicestudio
VoiceStudio is an Electron desktop app with a Python backend for voice cloning, text-described voice design, timed video dubbing, dictation, transcription and audiobook creation. The default engine is k2-fsa/OmniVoice, with other engines selectable and models installed through a Model Manager. It also exposes a local API and an MCP server for agents.
Who it is for: Creators and self-hosters who want local voice cloning, dubbing and dictation
Strengths
- Covers cloning, voice design, dubbing, dictation and audiobooks in one app
- CUDA on NVIDIA, Metal on Apple Silicon, and a CPU fallback
- Local API and MCP for agents, plus watch folders and reusable recipes
- Installers for macOS, Windows and Linux, plus Docker
Weaknesses
- AGPL-3.0 app licence; model weights and voices carry separate terms
- CPU-only use is slower; CPU PyTorch setup needs about 5 GB disk
- Intel Mac runs the UI only and needs a remote backend
- Windows on ARM is experimental and CPU only
- GPU optional
- Docker + Compose
- Needs Electron, Python, PyTorch, Bun (source build), Node.js 22+ (source build)
- Models: k2-fsa/OmniVoice
xiaozhi-esp32
C++ firmware that turns ESP32 boards into a voice chatbot. It does offline wake-word detection with ESP-SR and streams Opus audio over WebSocket or MQTT+UDP to a server that handles ASR, LLM and TTS. MCP is used on the device (speaker, LED, servo, GPIO) and in the cloud (smart home, email, search). It connects to the hosted xiaozhi.me server by default, and self-hosted server projects are listed.
Who it is for: Hardware hobbyists and embedded engineers building ESP32 voice assistants
Strengths
- Supports 138 board directories and 171 release variants across ESP32, C3, C5, C6, S3 and P4
- Documented WebSocket and MQTT+UDP protocols let third-party servers and clients interoperate
- Offline wake-word detection with customizable wake words; Wi-Fi, Ethernet and Cat.1 4G networking
- Prebuilt firmware can be flashed without setting up a development environment
Weaknesses
- Models do not run on the device; a server is needed for ASR, LLM and TTS
- Default setup depends on the hosted xiaozhi.me service and an account
- Requires ESP-IDF 6.0.1 or later; 5.x is unsupported and the v6.1 tag has a reported C3 Wi-Fi bug
- Beginner tutorials are on Feishu and bilibili, mostly in Chinese
- no GPU
- Needs ESP-IDF 6.0.1+, ESP32 board, xiaozhi.me or compatible server
- Models: Qwen, DeepSeek, Realtime end-to-end voice models
