What is an AMR file?

AMR (Adaptive Multi-Rate) is a highly compressed audio format designed for speech on phones. It is what a lot of older phone voice recorders, call recordings, and voice memos produce. The heavy compression keeps files tiny, but many desktop tools do not read AMR at all.

How to convert AMR to text

SnailText turns a AMR into text locally, in four steps:

  1. Open the Transcribe files screen in SnailText.
  2. Drop in your AMR file, or a whole folder of them.
  3. Pick your output: plain text, Markdown, JSON, or SRT / VTT subtitles.
  4. Run it. The transcript is saved next to your files or wherever you choose.

The Whisper speech model transcribes on your own machine, so the audio never leaves your computer and there is no per-minute charge. AMR is a audio format, so SnailText uses a codec pack it downloads once inside the app. After that one-time download it works offline, and transcription runs fully on your machine.

You have AMR files from a phone recorder or a call-recording app, and you want them as text. SnailText reads AMR and transcribes it locally, so you do not need to find a converter that accepts the format or upload your recordings to a server.

Free AMR to text converter, no upload

Most "amr to text online" tools upload your file to a server and cap you at a few minutes unless you pay. SnailText is the opposite: it transcribes AMR on your device, so nothing is uploaded, there is no length limit beyond your own memory, and the free tier has no per-minute meter. That makes it a fit for anything sensitive, recordings with names, client audio, or private notes, where sending the file to a web service is the thing you want to avoid.

AMR to text: transcript, subtitles, and more

AMR transcription is not just plain text. Pick your output before the run and SnailText writes any of these:

  • · Plain text (TXT) for a clean transcript you can read, search, and edit.
  • · SRT and VTT subtitles with phrase-level timestamps, ready to drop onto a video.
  • · Markdown with a heading per file, handy for notes and docs.
  • · JSON for feeding the transcript into your own scripts or tools.

AMR to text FAQ

How do I transcribe an AMR file?
Add the AMR file to SnailText's Transcribe files screen. It handles AMR through its codec pack (a one-time download the app does for you), then transcribes it locally with the Whisper model. Nothing is uploaded, and many web tools do not accept AMR at all.
Why is my AMR file so small?
AMR uses heavy compression tuned for speech, so recordings are tiny. That is great for storage, but the trade-off is that fewer apps support it. SnailText reads AMR natively and transcribes it locally, so you do not have to convert it first.
Is AMR transcription free?
SnailText's free tier transcribes locally with the compact Whisper models, no account and no per-minute meter. Pro adds the larger, more accurate models and an optional on-device AI cleanup pass, $7.49/mo or $89/yr for up to 3 devices.
Can I transcribe a whole folder at once?
Yes. Drop a folder (or several files) into the Transcribe files screen and SnailText processes them one after another, writing a transcript for each. It scans the files directly in the folder. You can also drag and drop files straight in.
Can I get SRT or VTT subtitles?
Yes. Pick SRT or VTT as the output before you run the transcription and SnailText writes a subtitle file with phrase-level timestamps. Choose it up front, since subtitles are produced during the run. You can also export plain text, Markdown, or JSON.
What languages can it transcribe?
SnailText transcribes in the full set of Whisper languages (99), and can auto-detect the language or let you pick. Everything runs locally, so multilingual transcription works with no internet after the model is downloaded.
