Transcribe a WhatsApp voice note for free: every method (and its real catch)

iPhone: the 100% free and private method

If you're on iPhone, you already have the best free option, and it's built in. WhatsApp has been able to transcribe voice messages in French since iOS 16, with no subscription, no limit on the number, and no extra app.

Its big advantage isn't only the price: the processing happens entirely on your phone. The audio isn't sent to any server to be transcribed, which preserves end-to-end encryption. On privacy, no third-party solution does better, Abrège included.

You just need to turn it on once, and the classic catch is that the option stays invisible while Siri is off, since WhatsApp relies on Apple's speech recognition.

Android: native doesn't speak French (the real catch)

This is the information almost no page states clearly, and it changes everything if you're on Android: WhatsApp's built-in transcription does exist on Android, but it only supports English, Portuguese, Spanish and Russian. French isn't on the list.

In other words, if you're trying to transcribe a voice note in French for free on an Android phone, the native feature won't help, even up to date, even on a recent device. Many people spend ages digging through settings for an option that, in their language, doesn't exist.

That leaves web tools and third-party apps, also free, but with other trade-offs.

Free web tools and apps: read the small print

There are many sites and apps that transcribe audio for free. Some are very decent. But "free" there covers four different trade-offs worth spotting before you start.

Friction, first. A web tool asks you to export the voice note from WhatsApp, leave the app, open a browser, upload the file, wait, then copy the text. For one message, fine. For five messages a day, you give up after two days.

Privacy, next. Uploading a private voice note to an unknown service means handing a loved one's voice to a third party whose terms and retention policy you haven't read. It's the point most often left unsaid.

Hidden limits, too: minutes per month, maximum length per file, degraded quality on the free version, or blocked export. They usually appear after the first successful try.

And finally forced sign-up, when "free" turns into an account to create, ads, or a seven-day trial that renews on its own.

Transcription or summary? The difference that changes everything

There's a point these comparisons almost always forget, and it matters more than the price. All the methods above do the same thing: they convert voice into text, word for word.

But a transcribed four-minute voice note is about 600 words. Roughly four minutes of reading, digressions included, with the "ums", the repetitions and the three sentences about the weather before getting to the point. You changed the message's format, you didn't get your time back.

A summary does something else: it pulls out the key points and what's expected of you, in three lines readable in fifteen seconds. For a short message, transcription is plenty. For a five-minute monologue where a single sentence concerns you, it's the summary that actually solves the problem.

Abrège: 5 free summaries a month, inside WhatsApp

Let's say it plainly in the first sentence: Abrège offers 5 free summaries a month, no card or sign-up, and beyond that it becomes paid, from €3 a month. So it's not a free-for-life solution, unlike your phone's native feature.

What it brings in return comes down to two things. First you get a summary rather than raw text, so the gist rather than the whole thing. Second there's no friction: you forward the voice note to the Abrège contact in WhatsApp, like to a friend, and the reply arrives in the conversation. No export, no upload, no site to open, and it works in French on Android as well as iPhone.

On privacy, let's be precise rather than flattering: the audio is transcribed via OpenAI's API (Whisper), then deleted from our servers with no copy kept, hosted in Europe. It's server-side processing, so iOS's native transcription, which never leaves your phone, stays more private. If absolute privacy is your number-one criterion and you're on iPhone, use the native feature, honestly.

Which method to choose for your situation

If you're on iPhone and your voice notes are short, turn on native transcription: free, unlimited, and nothing leaves your phone.

If you're on Android and your voice notes are in French, the native feature will be no use. You need a third-party tool, web or by forwarding.

If you get a few long voice notes a month and want the gist rather than all the text, a summary suits better than a transcription, and 5 a month is enough for many people.

If you handle voice notes all day, no free plan will go the distance, neither ours nor anyone's: you'll have to pick a paid tool, ours or a competitor's.

And if above all you want to spend nothing, whatever the friction, free web tools do the job, provided you accept the manual export and check what the service does with your files.
