Fully local, private and cross platform Speech-to-Text with LLM Post-processing

What it solves

Murmure is a privacy-focused speech-to-text application that allows users to transcribe voice recordings into text locally on their own device. It eliminates the need for an internet connection and prevents data collection by ensuring no audio or transcription data ever leaves the computer.

How it works

The application uses NVIDIA's Parakeet TDT 0.6B v3 neural network (specifically an int8 ONNX export of a fine-tuned 'parakeet-ultra' model) to perform fast, low-latency transcription directly on-device. It supports 25 European languages and provides a clean interface for recording and instant text output.

Who it’s for

Users who prioritize privacy and offline capability, as well as those who want to hands-free dictation for AI prompts (such as Cursor, ChatGPT, or Claude), note-taking, or capturing creative ideas.

Highlights

  • Local Processing: All computation happens on-device with zero telemetry, tracking, or analytics.
  • Multilingual Support: Supports 25 European languages.
  • Cross-Platform: Available for Windows, Linux, and macOS (Intel and Apple Silicon).
  • Open Source: Released under the GNU AGPL v3 License.
  • Integration: Can be used to dictate directly into other applications or be post-processed by local LLMs.

    MacParakeet is a free, open‑source macOS app (Apple‑Silicon only) that provides on‑device dictation, file/URL transcription, and meeting recording with local speech‑to‑text engines (Parakeet, Nemotron, WhisperKit, Cohere). It offers a UI for live transcription, library management, calendar‑aware auto‑recording, and optional cloud AI features (summaries, chat, text transforms). A companion CLI (`macparakeet-cli`) enables scriptable automation. Install via notarized DMG, Homebrew cask, or build from source.

    hyprwhspr is a native Linux speech‑to‑text app that runs as a system‑wide service. It uses local models (Whisper, Cohere, Parakeet, Qwen3‑ASR, etc.) for near‑real‑time dictation, optionally falls back to cloud APIs, and integrates with Wayland/X11 desktops, status bars, and a themed visualiser. Install via the AUR or a one‑line script, configure with `hyprwhspr setup`, then toggle dictation with `Super+Alt+D` to have transcribed text auto‑pasted into any window.
