A privacy-first, open-source speech-to-text application that runs entirely on your machine, powered by a neural network via NVIDIA’s Parakeet model for fast, local transcription. Murmure turns your voice into text with no internet connection and zero data collection, and supports 25 European languages.
- Privacy First: All processing happens locally on your device. No data ever leaves your computer.
- No Telemetry: Zero tracking, zero analytics. Your data stays yours, always.
- Open Source: Free and open source software. Inspect, modify, and contribute.
- Powered by Parakeet: NVIDIA’s state-of-the-art speech recognition model runs entirely on-device for fast, low-latency transcription.
Bulgarian (bg), Croatian (hr), Czech (cs), Danish (da), Dutch (nl), English (en), Estonian (et), Finnish (fi), French (fr), German (de), Greek (el), Hungarian (hu), Italian (it), Latvian (lv), Lithuanian (lt), Maltese (mt), Polish (pl), Portuguese (pt), Romanian (ro), Slovak (sk), Slovenian (sl), Spanish (es), Swedish (sv), Russian (ru), Ukrainian (uk)
The Windows build is self-signed, as I'm not paying certification authorities just to remove the SmartScreen warning. Because of that, Windows may show a security message when you install it. The installer is safe, it will simply build its reputation over time as more users run it, and the warning will gradually disappear.
- Download murmure_1.2.1_x64_en-US.msi from the release page
- Run the installer and follow the setup wizard.
The experimental AppImage currently runs slower for transcription, and the update checker isn’t functional yet. A faster, improved version will be released in the coming days.
- Download murmure-x86_64.AppImage from release page
- Make it executable:
chmod +x murmure-x86_64.AppImage - Run the AppImage.
Murmure provides a clean and focused speech-to-text experience. Once launched, simply start recording your voice. The text appears instantly, processed directly on your computer.
Typical use cases include:
- Dictating to any AI prompt (Cursor, ChatGPT, Mistral, etc.)
- Writing notes hands-free
- Capturing creative ideas or dictation
Because all computation is local, no network connection is required.
Murmure uses NVIDIA’s Parakeet TDT, a highly optimized, experimental transformer-based speech recognition model designed for low-latency, on-device inference. It combines fast transcription with strong accuracy across multiple languages, running efficiently on consumer GPUs or CPUs.
