AMR to text on iPhone: transcribe .amr files

You have an old phone recording or a voicemail file, AMR was the classic mobile-voice format, and you need the words in it as text. You don’t need a converter, an mp3 tool, or a desktop app: transcription apps accept .amr directly.

Short answer

Import the file into AI Transcribe (tap Import, choose Audio File, pick your .amr file) and the transcript appears with timestamps and speaker labels. Files up to 3 hours are supported, and the format is converted internally, so no preparation is needed.

What is a .amr file?

AMR (Adaptive Multi-Rate) is the speech codec of the GSM era: old phone recorders, answering machines and many voicemail systems produce it. Files are tiny and speech-only, which is exactly what transcription needs.

AMR to text, step by step

Get the file onto your iPhone (Files, Downloads, or shared from another app).
Open AI Transcribe and tap Import → Audio File.
Select the .amr file. It’s converted and transcribed automatically, keep the app open while it processes.
Use Summarize or any of the 20+ AI tools on the result, or export the transcript as text or PDF.

On a Mac or in a browser

Import the .amr file on your iPhone as above. AI Transcribe for Mac records calls and meetings with both sides captured. Sign in with your email and every transcript also opens in the web library on any computer, where you can read it, export it as text, Markdown or subtitles, or share it as a link.
