Welcome to Speed of Sound

Voice typing for the Linux desktop: press a key, speak your text, and it types itself. That's it.

Features

  • Offline, on-device transcription using Whisper. No data leaves your machine.
  • Types the result directly into any focused application using Portals for wide desktop support (X11, Wayland).
  • Multi-language support with switchable primary and secondary languages on the fly.
  • Works out of the box with the built-in Whisper Tiny model. Download additional models from within the app to improve accuracy.
  • Optional text polishing with LLMs (Anthropic, Google, OpenAI), with support for a custom context and vocabulary.
  • Supports self-hosted services like vLLM, Ollama, and llama.cpp (cloud services supported but not required).
