About Speed of Sound
Speed of Sound is a voice-typing app for the Linux desktop.
By default, transcription runs entirely on-device, so no audio ever leaves your machine.
The app ships with a built-in multilingual Whisper model and supports additional models from the
Whisper, Parakeet, and Canary families to improve accuracy.
• Offline, private transcription with popular open speech models (Whisper, Parakeet, Canary)
• Multiple activation options: click the in-app button or use a global keyboard shortcut
• Types directly into any app via XDG Desktop Portals (supports X11 and Wayland)
• Optional text polishing with LLMs, supports self-hosted services like Ollama, vLLM, and llama.cpp
• Optional cloud providers supported for resource-constrained hardware environments
Please visit speedofsound.io/getting-started after installation.
