VoiceStudio

Local voice cloning, dubbing, and transcription across 646 languages, packaged as a desktop app that runs on your own hardware.

What’s new here

VoiceStudio fits the Model hosting and compute theme as a local app rather than a cloud compute layer. It runs voice cloning, video dubbing, dictation, transcription, and audiobook generation on your own machine, with remote services optional. It exposes a local API and an MCP server so agents can call it too. The default engine is k2-fsa/OmniVoice; other engines are selectable from a built-in catalog.

What it does

VoiceStudio is a desktop application for voice AI work that runs locally on Apple Silicon Macs, Windows, and Linux. On Intel Macs only the app UI runs, and it connects to a remote backend.

  • Voice cloning: provide a reference recording, enter text, generate speech.
  • Voice design: describe a voice in text and generate it from scratch.
  • Video dubbing: replace audio tracks in video files with timed synthesized speech.
  • Dictation: floating widget for speech-to-text input.
  • Transcription and audiobook creation: batch jobs for converting audio or text files.

The app supports CUDA on NVIDIA GPUs, Metal (MPS) on Apple Silicon, and CPU-only mode for machines without a dedicated GPU. It ships with 42 releases as of v0.5.6 and covers 646 languages. A local API and MCP integration let coding agents drive audio workflows directly.

Who it’s for

Developers, content creators, and researchers who want ElevenLabs-style voice capabilities without sending audio to a third-party API. Also useful for anyone building agent workflows that need speech synthesis or transcription as a local service, since VoiceStudio exposes both a local API and an MCP endpoint.
