SpeakwiseFree M4A to Text: Transcribe M4A Audio with Speaker Labels
Upload an m4a (the default iPhone Voice Memos format) and get an accurate, speaker-labeled transcript in minutes - free, in your browser, no install.
How it works
1. Upload your M4A
Drag in an m4a (or mp3, wav, aac, ogg) - up to 70 MB.
2. We transcribe it
Accurate text in 90+ languages, with each speaker labeled.
3. Edit & export
Rename speakers, copy the transcript, or download TXT / SRT.
It labels who said what
M4A is what an iPhone Voice Memo or a QuickTime recording saves by default - and most converters hand back one undivided wall of text. This one labels each speaker automatically (Speaker 1, Speaker 2…). It works the same for mp3, wav, aac and ogg too - rename the labels, then copy or export.
Sample output
An example of a speaker-labeled transcript - each voice detected automatically.
Speaker 1I recorded the whole planning session on my phone - it saved as an m4a. Can you pull the text out of it?
Speaker 2Yep, just upload it. It'll label each of us so we can see who took which action item.
Speaker 1Perfect - that's exactly what I needed for the recap.
Who it's for
Anyone with an m4a file: iPhone Voice Memos, meeting recordings, interviews and lectures - any m4a you want turned into accurate, speaker-labeled text you can search, edit and share.
