How do I turn a WhatsApp voice note into text?

Get the voice note out of WhatsApp as a file (on iPhone: open the chat, tap the contact or group name, Export chat, With selected media, pick the voice note, then Save to Files; on Android: More options, More, Export chat, Include media), then upload it here. WhatsApp voice notes are Ogg files with Opus audio, and Slice takes them as they are, whether the file ends in .opus or .ogg, along with M4A, MP3, WAV and most other audio, up to 600MB. You get the text on screen plus .txt, .srt and .vtt files, with speakers labelled if more than one person talks. The language is detected from the audio, so it does not matter what language your phone or WhatsApp is set to. Free: two recordings a month, each up to 1 hour; the first needs no account. For more, Slice Transcribe hour packs (1 hour for $1.99, 5 hours for $4.99, 15 hours for $9.99 or 40 hours for $24.99) are paid once and never expire, and each voice note uses only its length, rounded up to the minute. Audio is deleted after 7 days.

Getting the voice note out of WhatsApp

WhatsApp’s own Help Center gives one way to take media out of a chat: Export chat.

iPhone

  1. Open the chat and tap the contact’s name or the group name.
  2. Tap Export chat, then With selected media, and pick the voice note.
  3. Choose Save to Files. WhatsApp saves the export as a ZIP file.
  4. In the Files app, tap the ZIP to open it. The voice note is inside as an audio file.

Android

  1. Open the chat, tap More options, then More, then Export chat.
  2. Tap Include media. WhatsApp attaches the chat’s most recent media, so this works best for a recent voice note.
  3. Choose how to send it. WhatsApp lists Quick Share, Gmail or Chat as examples; emailing it to yourself is the simplest way to reach the device you will upload from.

Then upload the audio file here. The chat’s text file that comes with it is not needed.

What .opus is, and why there is nothing to convert

WhatsApp’s developer documentation says voice messages are .ogg files encoded with the Opus codec. Opus is the sound; Ogg is the box it comes in, and a file like that can be named .opus or .ogg. Some music players will not play it, which is why many guides tell you to convert it to MP3 first.

You do not need to here: Slice takes Ogg audio directly. Converting only adds a step and a website that sees your file. If a browser refuses the .opus name, renaming it to .ogg is enough, because it is already an Ogg file. Renaming it to .mp3, which some guides suggest, does not change what is inside and is not needed.

Files Slice does not take: .amr and .3gp, which some Android recorders make. Convert those to MP3 first.

WhatsApp’s own transcripts

WhatsApp can show a transcript of a voice message you receive: turn on Voice Message Transcripts in Settings, Chats, choose a language, then tap and hold a message and tap Transcribe. WhatsApp says the transcripts are made on your device, that the sender cannot see them, and that the feature is only on some devices for now. On iPhone it needs iOS 16 or newer with Siri on.

Use this page when:

  • The voice note is in a different language from the one you chose in WhatsApp.
  • The feature is not on your phone yet.
  • You sent the voice note yourself and want it as text.
  • You need the words as a file to keep, quote or translate, rather than on screen in the chat.

Long voice notes and lots of them

Most voice notes are a few minutes; some run much longer. Any voice note up to 1 hour is free, two a month. With hour packs, there is no count: each one uses its own length, rounded up to the minute, and a file can be up to 3 hours. Hours never expire, so a pack bought for one batch of voice notes is still there next time. All the packs are on Slice Transcribe.

How to transcribe a WhatsApp voice note

  2. 2Save the fileSave to Files on iPhone and open the ZIP, or email it to yourself on Android.
  3. 3Upload it hereThe .opus or .ogg file as it is, up to 600MB.
  4. 4Read or downloadThe text appears on screen and is emailed to you, with .txt, .srt and .vtt files.

Questions

Does it take .opus files?
Yes. A WhatsApp voice note is an Ogg file with Opus audio inside, and Slice takes Ogg. Upload the .opus or .ogg file as it is; there is nothing to convert. If your browser ever says it is not a type we take, rename the ending from .opus to .ogg and try again. It is the same file, and .ogg is the name browsers know as Ogg audio.
WhatsApp can transcribe voice messages itself. Why use this?
If WhatsApp’s transcript works for you, use it. WhatsApp says its transcripts are made on your phone, for messages you receive, in one language you choose in Settings, and that the feature is only on some devices. A voice note in a different language from the one you chose may not come out right, and WhatsApp’s help pages do not describe a way to save the transcript as a file. Here the language is read from each recording, and you get text and subtitle files you can keep.
How do I save just one voice note?
On iPhone, WhatsApp’s Export chat has With selected media, so you can pick only the voice note you need; it is saved as a ZIP, which you open in the Files app to get the audio file out. On Android, Export chat with Include media attaches the chat’s most recent media, so an old voice note may not be in it.
Is it free?
Yes, for two recordings a month, each up to 1 hour, with no card. For lots of voice notes, the pack of 1 hour ($1.99) covers about 20 notes of 3 minutes each, because each one uses only its own length rounded up to the minute.
Is it private?
WhatsApp messages are end-to-end encrypted inside WhatsApp. Once you save a voice note and upload it here, it is a file you have chosen to share: it goes to private storage, is sent to AssemblyAI to be transcribed, and is deleted after 7 days. A free transcript is deleted after 30 days. Nothing is used for training. Only upload someone else’s voice note if they would be fine with it.
Can I transcribe a voice note in Spanish, Portuguese, French or another language?
Yes. The language is detected from what is said, and the transcript comes back in that language, so a family chat that mixes languages works one voice note at a time. Accuracy is best in English; check names against the recording.
