About Blurt
Blurt is a GNOME Shell extension that brings accurate offline speech recognition to any text input field on Linux. It uses whisper.cpp, a lightweight C++ implementation of OpenAI's Whisper model, to deliver multilingual speech-to-text without needing an internet connection — ensuring privacy and low latency. Targeted at Linux users who need hands-free text entry, Blurt is ideal for writers, developers, accessibility users, and anyone who prefers dictation over typing. It integrates seamlessly into the GNOME desktop environment, allowing users to invoke speech input via a middle mouse button click or the CTRL+V shortcut. The extension depends on the `wsi` (Whisper Speech Interface) script, available on GitHub, which must be installed separately. Blurt is actively maintained and supports GNOME Shell versions 42 through 48. For users seeking a cross-desktop environment solution, the developer offers BlahST, a sibling tool that works on any Linux desktop. Blurt is free and open-source, with a strong focus on offline functionality — setting it apart from cloud-dependent dictation tools. Its accuracy and speed rely on the chosen whisper.cpp model, which can be swapped based on user preference for language or performance.
Behind the Verdict
Blurt fills a narrow but important niche: offline dictation on GNOME. If you're a Linux user who values privacy and works in a language Whisper supports, this extension is worth the setup effort. The integration with any text field via middle-click or Ctrl+V is elegant and fast. However, the dependency on `wsi` means it's not a one-click install — you'll need to follow the GitHub instructions. Compared to cloud-based alternatives like Google's voice typing, Blurt keeps everything local, but accuracy may vary based on the model you choose. For non-GNOME desktops, the developer recommends BlahST. In practice, Blurt works well once configured, but it's not for users who expect a plug-and-play experience. We'd recommend it for privacy-conscious GNOME users who are comfortable with basic command-line setup.
