How to transcribe WhatsApp audio to text, from voice note to PDF

Voice notes are easy to send and hard to work with: you can’t search them, quote them or file them away as text. With FilmScribe, you upload the voice message file exactly as WhatsApp saved it and get the text back word for word, with a timestamp for each part. Then you review it by listening and download it.

This guide shows how to save the audio on iPhone, Android and a computer, how to transcribe it in FilmScribe, and what to do with the text: file it, quote it, translate it or turn it into meeting notes.

In short

• Save the audio to your device first: on a phone, through Share; on WhatsApp Web or the desktop app, through Download.
• Upload it to FilmScribe without converting. OPUS and OGG, WhatsApp’s formats, go in as they are.
• Get the text with timestamps and review it by clicking a sentence to hear that part.
• For several voice notes from the same chat, export the chat with media, unzip it and keep everything in one folder.
• Download TXT, PDF or SRT, or copy the text straight from the app.

How to transcribe WhatsApp audio in FilmScribe

1. Save the voice message

WhatsApp keeps the audio inside the chat, so the first step is getting the file out. The exact taps vary a little by device and are summed up in the next section. What matters: save the original file instead of recording the sound again with another app. Re-recording through the speaker loses quality and adds room noise.

2. Upload the file without converting

In FilmScribe, upload the file just as it came out of WhatsApp. Voice notes come as OPUS or OGG, and audio forwarded from other apps usually comes as M4A or MP3. All of them go straight in, with no converter. If the message is a video, upload the MP4: we transcribe the sound of the video the same way.

If you have several voice notes on the same subject, create a folder named after the contact, the client or the project and keep them all there. A month from now, you’ll find the conversation by name instead of by date.

3. Get the text word for word

We transcribe the audio word for word, with the time of each part. When there is more than one voice, like a recorded call or a meeting voice note, the lines come back separated by speaker. The language is detected automatically, among 90+ languages, so a voice note in Spanish or Portuguese comes out in the language it was spoken in.

4. Review while listening

WhatsApp audio is often recorded while walking, driving or with the phone far from the mouth. So it pays to review: click a sentence to hear the audio at that point and fix proper names, phone numbers, amounts and addresses right in the text. Search inside the transcript helps you find a word in long voice notes.

5. Download, copy or file it

Once the text is reviewed, pick the format:

Example: a client’s voice note as text

An interior designer gets a 2 minute 40 second voice note from a client with changes to a kitchen project. Instead of listening three times and taking notes, she saves the audio, uploads it to FilmScribe and gets:

[00:00] Hi Carla, hope you're well. We went over the plans last night and we love them.
[00:09] Just three things: can the countertop be white quartz instead of granite?
[00:21] We'd like the island 4 feet wide, not 3.
[00:34] And the budget cap is still 48,000, cabinetry included.
[01:02] Oh, and work can only start after November 15.

She checks the numbers by listening to the parts at 00:21 and 00:34, copies the three requests into her confirmation email and saves the PDF in the client’s folder. If the client later says she asked for a different size, the sentence is there, with the minute.

Common problems and how to fix them

• The file won’t play on my computer. WhatsApp audio comes as OPUS, which some players can’t open. You don’t need to play it: upload the file to FilmScribe as it is.
• I got a ZIP file. That is an exported chat. Unzip it and upload the audio files, one by one or all into the same folder.
• Lots of background noise. Traffic, wind and music get in the way of any transcription. Review the noisiest parts more carefully, listening to the audio at that point.
• Two people talking at once. Lines come back separated by speaker whenever the voices take turns. Where they overlap, check by listening.
• It’s a video message. WhatsApp videos can be uploaded as MP4, and we transcribe the sound. If you only want the sound, the extract audio from video tool gives you an MP3.

How to save WhatsApp audio on each device

The exact menu can change between app versions, but the idea is the same: find the option to share or download the message.

• iPhone: touch and hold the voice message, tap Forward, then the share icon. Choose Save to Files. The audio lands in the Files app, ready to upload to FilmScribe from your browser.
• Android: touch and hold the voice message and use the Share icon to save the file or send it to your email or Drive. Voice notes are also kept in WhatsApp’s media folder, under “WhatsApp Voice Notes”.
• WhatsApp Web and the desktop app: hover over the message, open the arrow menu and click Download. The file goes to your downloads folder.
• Whole chat: open the chat, tap More, Export chat and choose to include media. WhatsApp creates a ZIP with the text and the audio files. Unzip it before uploading: FilmScribe takes the audio files, not the ZIP.

What about WhatsApp’s own transcripts?

On some devices and in some languages, WhatsApp transcribes a voice message inside the chat. For reading a quick note without playing it, that works well.

That’s where it stops: the text stays in the chat, with no timestamps, no speaker separation and no export. When the audio needs to become a document, a quote, meeting notes or a work record, save the file and transcribe it in FilmScribe.

When it’s worth transcribing WhatsApp audio

• Client work. A request, brief or approval that came in as a voice note becomes text you can paste into a quote, a contract or your company’s system. See how it looks in customer support.
• Meetings and agreements. A long voice note with decisions becomes meeting notes, with the time of each point.
• Interviews and research. An answer a participant sent by voice note joins your research material with timestamps, just like a recorded interview. The guide on how to transcribe an interview covers the conventions.
• Church and groups. A devotional, a note from the pastor or a study shared in the group becomes text for the blog, the bulletin or people who prefer to read. See devotionals.
• Family memories. Voice notes from people you don’t want to forget become text you can keep next to the original file.

Good practices

• Keep the original file. The text is for reading and searching; the audio is the record. Don’t delete the message after transcribing it.
• Ask before sharing. A voice note sent to you isn’t public. Before posting or forwarding the text, check with the person who recorded it.
• Double-check numbers and names. These are where one mistake changes the meaning: amounts, dates, addresses and proper names.
• Keep the original language. If the voice note is in another language, transcribe it in the spoken language first. On Studio and Agency, translate it afterwards into 9 languages.
• For legal use, talk to a lawyer. A transcript helps organize the conversation, but evidence usually calls for its own formal steps.

Free tools that help

• Free audio to text: start with the trial and see your audio as text.
• Words to minutes: estimate how long the text takes to read aloud, useful if the voice note is turning into a script.
