Offline transcription

How to transcribe audio without an internet connection

Offline transcription means the speech-recognition model runs on your phone instead of sending the recording to a server. That matters when you have no signal — and when the recording is sensitive.

1. Download the speech model once

True offline transcription still needs an initial model download. Do this on Wi-Fi before travelling, entering a secure location or working somewhere with poor connectivity.

2. Record or import the audio

You can record a new conversation or import an existing audio or video file. The important distinction is where transcription happens, not where the recording originally came from.

3. Run speech-to-text on the device

The phone processes the audio locally. No network request is required for transcription once the model is installed, so airplane mode is a simple way to verify an offline workflow.

4. Search, correct and export locally

Once the transcript exists, review speaker labels, search the text and export the result. If privacy is the reason you chose offline transcription, check whether optional sync features are enabled before sharing or backing up files.

Start with your next conversation.

Download Murmur, download a speech model once, and every recording after that is transcribed on your own device — meetings, interviews, lectures, ideas on a walk.

Free to download · No account · Works with no signal

On iPhone and iPad the free version transcribes the first 20 minutes of each recording; Murmur Pro is a one-time purchase that lifts the limit. On Android, transcription is currently free with no recording-length limit.
