How to Transcribe Voice Memos From an iPhone or Android

The phone in your pocket is the most common recording device in the country, and phone recordings are where most transcription work starts.

Getting the file off the phone

iPhone. Voice Memos records to M4A. Open the recording, use the share button, and send it to yourself by email or save it to Files. Do not screen-record it, and do not play it aloud while recording on something else.

Android. The app varies by manufacturer — Recorder, Voice Recorder, Sound Recorder — and so does the format, usually M4A, AMR or 3GP. All of them share to email or Drive.

Whatever the format, upload the original. You do not need to convert it first, and converting adds a re-encode that costs you a little quality for no benefit.

AMR is worth a word

Some Android recorders still default to AMR, a format designed for voice calls at very small file sizes. It is heavily compressed and it audibly softens consonants.

If your recorder offers a choice, pick M4A or WAV. If you have already recorded in AMR, upload it as-is — converting it now cannot restore what the format discarded.

Where phone recordings go wrong

Distance. The single biggest factor. A phone on the table between two people is dramatically better than a phone in a shirt pocket. Halving the distance to the speaker helps more than any setting.

Pocket and hand noise. Fabric against the microphone produces a loud rumble that sits right on top of speech. Put the phone down.

Wind. Outdoors, wind across a bare phone microphone overwhelms everything. Shelter it with your body if you cannot move.

Notifications. Silence the phone before recording an interview. A message tone lands directly on the microphone and reliably lands mid-sentence.

Recording something on purpose

If you know in advance you will transcribe it, a few habits pay for themselves.

Put the phone on the table, screen up, roughly equidistant from whoever is talking. Ask people to speak one at a time — overlapping speech is the hardest thing for any system to separate. Say the names of participants at the start, which gives you a reference for labelling speakers later. And record the whole thing rather than starting and stopping, since a single continuous file keeps speaker labels consistent.

Then transcribe it

Upload, set the language to what is really in the recording rather than what sounds official, and read the first pass with the audio open to fix names and numbers.

If the recording turned out rough, these repairs apply to any phone audio, not just WhatsApp.
