How it works

Drop an .m4a recording above — a Voice Memo shared from your iPhone works as-is. Files up to 25 MB.
AI transcription
The speech is transcribed with AI recognition — memos, lectures, interviews, and calls all handled.
Copy your transcript
Copy the text into notes, emails, or documents — or call the API to transcribe recordings automatically.
Key features
What makes this m4a to text stand out.
Voice Memos ready
iPhone and iPad Voice Memos are M4A. Share the file from the app, upload it here, and read your memo as text.
No format conversion first
No need to convert M4A to MP3 before transcribing — ParseJet takes the file your phone produced directly.
Accurate AI speech recognition
Modern transcription models handle fast talkers, accents, and phone-mic recording quality.
Multilingual
Transcribe speech in dozens of languages; pass a language hint via the API for best results.
Word-level timestamps
Need timings for captions or navigation? The API returns word-level timestamps with the with_timestamps option.
All common formats too
The same endpoint takes MP3, WAV, OGG, FLAC, and WebM — every recording source through one integration.
Use cases
Common scenarios where this tool saves you time.
Voice memos to notes
Ideas, reminders, and meeting debriefs recorded on your phone become searchable text you can act on.
Lectures and interviews
Recordings made on iPhone in class or in the field transcribe into quotable, searchable transcripts.
Dictated drafts
Dictate a first draft on a walk, then transcribe it and edit text instead of retyping from audio.
AI workflows
Claude and ChatGPT can’t listen to audio — transcribe the memo first, then feed the text in for summaries and action items.
Automate with the API
Use the same tool programmatically. Works with any language — just HTTP.
# Transcribe an M4A recording curl -X POST https://api.parsejet.com/v1/parse/audio \ -H "Authorization: Bearer YOUR_API_KEY" \ -F "[email protected]" \ -F "language=en" # With word-level timestamps: # -F "with_timestamps=true"
import httpx
resp = httpx.post(
"https://api.parsejet.com/v1/parse/audio",
headers={"Authorization": "Bearer YOUR_API_KEY"},
files={"file": open("voice-memo.m4a", "rb")},
data={"language": "en"},
timeout=120,
)
print(resp.json()["text"]) # the transcript const formData = new FormData();
formData.append("file", m4aFile); // M4A, MP3, WAV, OGG, FLAC
formData.append("language", "en");
const res = await fetch("https://api.parsejet.com/v1/parse/audio", {
method: "POST",
headers: { Authorization: "Bearer YOUR_API_KEY" },
body: formData,
});
const { text } = await res.json();
console.log(text); // the transcript Want to automate this?
ParseJet API gives you the same parsing power via a single HTTP endpoint. No ffmpeg, no poppler, no tesseract — just one API call.
Frequently asked questions
How do I convert an M4A file to text?
Upload the .m4a file above — ParseJet transcribes the speech with AI recognition and shows the transcript. For automation, POST to /v1/parse/audio.
How do I transcribe an iPhone Voice Memo?
In the Voice Memos app, tap the memo → Share → Save to Files (or AirDrop it to your Mac), then upload the .m4a here. The transcript appears in seconds.
Do I need to convert M4A to MP3 first?
No — that extra step is exactly what this tool removes. ParseJet transcribes M4A directly, along with MP3, WAV, OGG, FLAC, and WebM.
How accurate is it?
Clear speech recorded near the microphone — the typical voice memo — transcribes with very high accuracy. Wind, distance, and crosstalk reduce it.
Can I get timestamps?
Yes. Pass with_timestamps=true to the API and the response includes word-level timings you can convert into SRT or VTT captions.
Is it free?
Yes. You get 3 free transcriptions per day with no signup. An audio file costs 1 credit; the free account includes 300 credits per month. Paid plans start at $19/month.
