iPhone Voice Memos to Text — Step-by-Step
iPhone Voice Memos save as M4A files by default. Here's the exact workflow to get a transcript from a Voice Memo recording:
- Open Voice Memos on your iPhone and tap the recording you want to transcribe.
- Tap the 3-dot menu (⋯) next to the recording.
- Tap "Share" and choose how to get the file off your phone: AirDrop (fastest if you're on a Mac), "Save to Files" (then access via iCloud Drive on any device), or email/Messages for shorter clips.
- On your computer or in the browser, upload the .m4a file to VexaScribe (or any M4A-compatible transcription tool).
- Wait 2-10 minutes (depends on length). Get the transcript with timestamps and speaker labels.
- Export as TXT (paste anywhere), DOCX (edit in Word), or SRT (subtitles for video).
iOS 17+ built-in transcription: Apple added native transcription to Voice Memos in iOS 17 (iPhone XS or newer required). Open a memo, tap the 3-dot menu, and look for the transcription option. It's good for quick personal notes but limited: shorter recordings only, no speaker labels, limited language support (English-focused). For longer recordings, multilingual content, or anything you want to share/edit professionally, an external tool gives much better output.
M4A File Size and Online Tool Limits
M4A is compressed (using AAC), so files are much smaller than WAV — but they still hit upload limits on free online tools when recordings get long. Here's what to expect:
| Source / quality | ~Size per minute | 1-hour file |
|---|---|---|
| iPhone Voice Memo (default) | ~0.5 MB | ~30 MB |
| iPhone Voice Memo (lossless) | ~5 MB | ~300 MB |
| GarageBand M4A export (256 kbps) | ~2 MB | ~120 MB |
| iTunes M4A purchase (256 kbps) | ~2 MB | ~120 MB |
Most free online "M4A to text" tools cap uploads at 25 MB — about 50 minutes of a standard iPhone Voice Memo, but only 5 minutes of lossless or high-quality M4A. If you're transcribing a multi-hour interview, lecture, or session, you'll hit the wall.
VexaScribe accepts M4A files up to 5 GB — easily enough for full-day recordings or long lecture series. No need to split files or compress them first.
What is M4A to Text Conversion?
M4A is Apple's default audio format, used by iPhone Voice Memos, iTunes, GarageBand, and other Apple applications. It uses the AAC codec, which delivers better audio quality than MP3 at the same file size.
Converting M4A to text with VexaScribe is straightforward — upload your file and our AI handles the rest. Whether it's a voice memo from a meeting, a lecture recording from your iPhone, or a GarageBand export, you'll get an accurate transcript with timestamps and speaker labels.

M4A to Text Conversion FAQ
How do I transcribe an iPhone Voice Memo to text?
Step-by-step: (1) Open the Voice Memos app on your iPhone and find the recording. (2) Tap the recording, then tap the 3-dot menu (⋯). (3) Tap "Share" and choose either "Save to Files", AirDrop, or email. (4) On your computer or in the browser, upload the .m4a file to VexaScribe (or any M4A-compatible transcription tool). (5) Get the transcript in minutes, exportable as TXT, DOCX, or SRT. Voice Memos save as .m4a by default, so no conversion needed.
How do I convert M4A to text?
Upload your M4A file directly to VexaScribe — no conversion to MP3 needed. The AI handles the AAC encoding M4A uses natively. Sources include iPhone Voice Memos, GarageBand exports, iTunes purchases, and many recording apps. The transcript includes timestamps, speaker labels, and is exportable to TXT, DOCX, or SRT. 30 minutes free on signup.
Can I convert M4A to text for free?
Yes. VexaScribe gives you 30 minutes free on signup — typically enough for one ~30-minute Voice Memo or several short recordings. Other genuinely free options: (1) iOS 17+ has built-in transcription for short Voice Memos (open the memo, tap the 3-dot menu, look for transcription option — works only on iPhone XS or newer and limited languages), (2) Whisper installed locally on your computer (100% free and private, requires Python), (3) free online tools but they typically cap files at 25 MB (about 15-30 minutes of M4A). For longer files or recurring use, paid plans start at $2/month.
Is M4A the same as iPhone Voice Memos?
Yes. iPhone Voice Memos save in M4A format by default — the file extension is .m4a. M4A is a container format that holds audio compressed with AAC (Advanced Audio Coding). It's also used by GarageBand, iTunes, and many other Apple apps. M4A has better quality than MP3 at the same file size because AAC is a more efficient codec. For transcription purposes, M4A and MP3 produce essentially identical accuracy on clear audio.
What's the difference between M4A and MP3 for transcription?
Both work well. M4A typically has better audio quality than MP3 at the same file size (AAC is more efficient than MP3 encoding), but for transcription accuracy the difference is marginal on clear audio. M4A files are typically 30-60 MB for an hour of iPhone Voice Memo audio; MP3 files at similar quality are usually 40-80 MB. If your transcription tool accepts both, just upload whichever you have — no conversion benefit.
How long does M4A to text conversion take?
A typical 1-hour M4A file takes about 5-10 minutes to transcribe. M4A's efficient compression means smaller files that upload faster than WAV. Shorter recordings (10-20 min) are usually ready in 1-3 minutes. You can close your browser tab while waiting — your transcript will be saved.
Can I convert M4A files in different languages?
Yes, VexaScribe supports M4A to text in 99 languages including English, Spanish, French, German, Portuguese, Italian, Mandarin, Japanese, Korean, Arabic, Turkish, Hindi, and many others. The language is auto-detected from the audio, or you can specify it manually for best results — useful if the recording starts in one language before the main content begins.
Note: Transcription accuracy depends on audio quality, background noise, speaker clarity, and accents. For best results with iPhone recordings, use the 'Lossless' quality setting in Voice Memos.
VexaScribe handles M4A files alongside MP3, WAV, FLAC, and all other audio formats. Transfer your Voice Memos and get text in minutes.
