How to transcribe a voice note someone sent you

People assume transcription only applies to something they recorded themselves, so a voice note that landed in Messages or WhatsApp gets played back, half-remembered, and eventually re-typed by hand when a quote from it is actually needed. That last step is the one worth skipping.

Find out where the file actually is

A voice note sent through Messages, WhatsApp, Telegram or similar is not sitting in your own recordings library — it is an attachment inside that app’s conversation. Most of these apps let you save the attachment to the Files app from a share or save option on the message itself. Once it is a file in Files rather than something trapped inside a chat thread, it can go anywhere a file can go.

If it arrived by AirDrop directly rather than through a messaging app, it likely saved straight into Files already, and this step is done for you.

Getting it into something that can transcribe it

This is the part that surprises people: you do not need to re-record the voice note by playing it out loud into a microphone, which is both awkward and lossy. An app that supports importing an existing audio file can take the file directly from Files and transcribe it exactly as if you had recorded it yourself — the transcription step does not know or care where the audio originally came from.

Voice Studio supports importing audio this way, so a voice note saved to Files can be brought in and transcribed alongside anything recorded in the app.

Set the language before you transcribe, not after

iOS speech recognition is told which language to expect; it does not detect the language from the audio itself. If the voice note is in a language other than whatever your transcription setting currently points to, you will get an empty or nonsensical result and it will look like the feature is broken. It is not — the setting is just pointed at the wrong language. Set it to match the language the voice note is actually in, not the language your phone’s interface happens to be in; those are two independent settings.

On-device or the server still applies here

A voice note someone sent you is still just audio to the speech recognizer, so the same on-device-first behaviour applies as for anything you recorded yourself: an on-device pass is attempted first, and only if that comes back empty or errors does a retry go to Apple’s server. Because this audio is someone else’s voice and not only yours, it is worth being a little more deliberate about that fallback than you might be for your own recordings — if you want certainty that a specific voice note was handled entirely on the phone, transcribe it in Airplane Mode, exactly as you would with your own audio. If the local model for that language is not there, you will get nothing rather than a transcript in that state, which is itself the useful signal.

What you will not get

Speaker labels are not part of the picture here, but for a typical voice note that barely matters — a voice note is usually one person talking, unlike a meeting or an interview. What is more likely to trip you up is a voice note recorded in a noisy environment, at a distance from whoever’s phone captured it, or heavily compressed by the app it was sent through before it ever reached you. None of that is something the transcribing app can undo; the transcript can only work with what is actually in the file.

Getting the text back out

Once transcribed, the text can be corrected the same as any transcript — names and unfamiliar terms are the most likely spots to need a fix, and that is equally true of someone else’s speech patterns as your own. From there, copy the text to reply with it, paste it into notes, or export it as a file if you want to keep the voice note and its transcript together rather than losing the connection between them once the original message gets deleted from the chat.

How Voice Studio handles this

Import an audio file from the Files app the same way you would start a new recording, choose the language the voice note is actually in, and transcribe it — the on-device path is attempted first exactly as it is for anything recorded in the app. The result behaves like any other entry in the library: it is searchable, the transcript is editable afterwards, and you can export it as TXT or JSON or share the audio file itself. Nothing about importing sends the file anywhere on its own; it stays in the app’s own storage until you choose to export or share it.

Common questions

Can I transcribe a WhatsApp voice note on iPhone?

Yes, if you save the voice note as a file first — most messaging apps let you save an attachment to the Files app — and then import that file into an app that supports importing audio for transcription.

Does transcribing an imported file work differently from transcribing something I recorded myself?

No. Once the audio is a file the app can open, transcription works the same way regardless of whether it was recorded in the app or imported — it attempts on-device recognition first either way.

Will it detect the language the voice note was recorded in automatically?

No. iOS speech recognition is told which language to expect rather than detecting it, so you need to set the transcription language to match the voice note before transcribing, separately from your phone or app’s interface language.

Is it private to transcribe a voice note someone else sent me?

The same rules apply as for your own audio: an on-device pass runs first, and a retry only goes to Apple’s server if that pass comes back empty or errors. Transcribing in Airplane Mode guarantees the on-device-only outcome if that matters for a particular message.
