MP4
Convert video and subtitles from MP4 files.
To convert a recording to text, upload the audio file from your phone, dictaphone or computer — Any2Text recognizes the speech with AI at up to 98% accuracy and returns an editable transcript with timestamps in minutes. Voice memos, lectures, interviews and calls in 50+ languages. The first minutes are free, no signup required.
Almost any voice recording can be turned into text — what matters is getting the audio file off the device. Here is where common recordings come from and what format they are saved in:
| Recording | Usual format | How to get the file |
|---|---|---|
| iPhone Voice Memos | M4A | Share → Save to Files, or AirDrop to a Mac |
| Android recorder apps | M4A, MP3, AMR | Share the recording or copy it from the Recordings folder |
| Dictaphone / digital voice recorder | MP3, WAV, WMA | Connect via USB and copy the file |
| Call recordings | MP3, M4A, AMR | Export from the call recorder app |
| Zoom, Teams and Meet recordings | M4A, MP4 | Download from the cloud or local recordings folder |
| Mac and PC recordings | M4A, WAV, MP3 | Upload directly from your computer |
iPhone Voice Memos are saved as M4A files, which Any2Text transcribes directly:
On a Mac, you can drag the memo straight from the Voice Memos app to your desktop and upload it. More about the format: M4A to text.
Open your recorder app, select the recording and tap Share — save it to your files or send it to yourself. Then upload the file here from your phone or computer. Most Android recorders save M4A or MP3, and both are supported, as well as AMR from older phones and call recorders.
Digital voice recorders store MP3, WAV or WMA files. Connect the recorder to your computer with a USB cable, copy the recording and upload it. Long recordings are fine — a multi-hour lecture or meeting is transcribed in one go, with timestamps so you can jump to any moment.
Recorded in one language but need the text in another? Any2Text first transcribes the recording in its original language, then translates the transcript into English or 50+ other languages, ready to export. See translate audio to text.
