Murmur: Voice to Text Recorder

Murmur is the voice recorder and speech to text app that understands who said what. Record a meeting, a lecture, an interview, or a quick voice memo, and Murmur turns it into searchable text — and tells each speaker apart — on your device by default. Optional cloud transcription uploads only recordings you choose.

WHY MURMUR

Most transcription apps upload your recordings to a server. Murmur transcribes on your phone by default, no account needed.

KNOW WHO SAID WHAT
Murmur labels each line of the transcript with who said it, color-coded so a multi-person conversation is easy to follow. It builds a library of people across your recordings: name someone once, and Murmur recognizes their voice the next time they appear. Merge duplicates or relearn a voice — the more you correct someone, the better Murmur identifies them later.

TURNS TALK INTO TEXT
Hit record, and Murmur transcribes what was said and saves the full transcript alongside the audio. Transcription runs on your phone and detects the spoken language automatically.

EXPORT — AND HAND IT TO YOUR AI
Export any transcript as plain text, Markdown, PDF, or Word — with each line's speaker, and your translation if you made one. Export subtitles as SRT or VTT, or share the original audio. Drop it into your notes, an email, or your favorite AI assistant to summarize, pull action items, or dig deeper — on your terms, with your tools.

IMPORT WHAT YOU ALREADY HAVE
Bring in a voice memo, a podcast episode, a meeting recording, a lecture, or any audio or video file, and Murmur turns the audio to text on-device with speakers labeled — just like something you recorded in the app.

TRANSLATE YOUR TRANSCRIPTS
Turn any transcript into another language, line by line, right inside the recording. Read it as translation-only or side-by-side with the original — all on-device.

EDIT AUDIO — THE TRANSCRIPT FOLLOWS
Cut right on the waveform: trim, keep just the part you need, remove every silence with one tap, or append another recording. The transcript re-times itself to the new timeline, so there is nothing to transcribe again.

WORKS OFFLINE
Because recognition runs on your device, Murmur keeps working fully offline — on a plane, in a basement meeting room, or anywhere with no signal. Download a model once and you are set.

GREAT FOR LEARNING AND FOLLOWING ALONG
Import a speech, a lecture, a podcast, or any audio you already have and study it your way: tap a single sentence to replay it, or let the whole recording play with the timestamped transcript scrolling along in sync. Many people use Murmur to learn a new language one sentence at a time.

SEARCH YOUR WORDS
Find a phrase across your recordings instantly, with matches highlighted right where they appear.

MULTIPLE LANGUAGES
Murmur transcribes around 100 spoken languages — accuracy is highest for the most widely spoken ones — and the app interface is available in English, German, Japanese, Simplified Chinese, Korean, and French.

SAVES SPACE AUTOMATICALLY
Once a recording is transcribed, Murmur quietly compresses its audio in the background, reclaiming storage without losing the transcript or playback.

WIDGET AND QUICK SETTINGS
Start recording from the home screen widget, the Quick Settings tile, or the app icon shortcut — without opening the app first.

PRIVATE BY DESIGN
- On-device transcription and speaker identification by default
- No account needed on-device
- Optional cloud transcription (sign-in required) uploads only recordings you choose: processed by Groq in the US, deleted within 30 days, never used for training
- Anonymous usage and crash diagnostics help us fix bugs — never your audio, never your words

Whether you are turning a meeting into meeting notes, keeping a record of an interview, or dictating ideas on a walk, Murmur gives you a clean, searchable transcript that knows who said what — while keeping your conversations yours.
