MurMur Voice to Text Software

Murmur uses OpenAI's Whisper model, running entirely on your local hardware, to achieve over 95% transcription accuracy across more than 90 languages with automatic language detection. On machines with a compatible GPU, transcription is hardware-accelerated — meaning text appears virtually the instant you release the hotkey. On CPU-only setups, it still performs respectably.

1

Place your cursorClick anywhere text input is accepted — a document, chat window, code editor, email client, terminal.

2

Hold the hotkeyPress and hold Ctrl + Win + Alt and speak naturally.

3

ReleaseText is inserted at cursor position automatically. No copy, no paste.

A secondary shortcut — Ctrl + Win + Shift — copies the last transcription to the clipboard if you need it elsewhere. Smart audio processing filters background noise automatically, so the quality of transcription remains consistent even in imperfect recording conditions.

Privacy, by Architecture

The privacy argument for Murmur is not a policy — it is a technical fact. Because the Whisper model runs on your machine, your voice data physically cannot reach any external server. There is no account to create, no API call to a cloud endpoint, no terms of service that may change. For professionals handling sensitive information, this distinction matters enormously.

Legal teams can dictate case notes. Medical practitioners can record patient observations. Developers can describe code in environments governed by NDAs. Journalists can protect source conversations. In each case, the guarantee is not a privacy pledge but an architectural impossibility of leakage.
