Pick voicestudio if you are

Creators and self-hosters who want local voice cloning, dubbing and dictation

  • Covers cloning, voice design, dubbing, dictation and audiobooks in one app
  • CUDA on NVIDIA, Metal on Apple Silicon, and a CPU fallback

Pick buzz if you are

People transcribing or subtitling audio and video locally on their own computer

  • Runs offline; transcription and translation stay on the local machine
  • Several Whisper backends: Whisper.cpp with Vulkan, CUDA, Apple Silicon, Hugging Face models

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

buzz

Buzz is a desktop app that transcribes and translates audio and video files, YouTube links, or live microphone input with OpenAI's Whisper, on the local machine. It supports several Whisper backends (Whisper.cpp with Vulkan, CUDA, Apple Silicon, Hugging Face models) and exports to TXT, SRT and VTT. It also has a CLI, a watch folder and a plugin system.

Who it is for: People transcribing or subtitling audio and video locally on their own computer

Strengths

  • Runs offline; transcription and translation stay on the local machine
  • Several Whisper backends: Whisper.cpp with Vulkan, CUDA, Apple Silicon, Hugging Face models
  • Speaker identification and speech separation for noisy audio
  • CLI and watch folder allow scripted or automatic transcription

Weaknesses

  • Current releases require Apple silicon; last Intel Mac version is 1.4.5
  • Windows installer is unsigned and triggers a security warning
  • PyPI install needs ffmpeg, Python 3.12 and manual torch CUDA setup for GPU
  • Export formats listed are only TXT, SRT and VTT
  • GPU optional
  • Needs ffmpeg (PyPI install), Python 3.12 (PyPI install)
  • Models: Whisper, Whisper.cpp, Hugging Face Whisper-type models
