How to transcribe a WhatsApp voice message to text

Voice notes are quick to send and slow to listen to. Here is how to turn any WhatsApp voice message into accurate, readable text in seconds — without leaving the chat.

Why transcribe a voice message at all?

A two-minute voice note can hold a name, a date, an address, and a decision — and you cannot skim any of it. You have to play the whole thing, often more than once, often somewhere you cannot put it on speaker. Text fixes all of that: you read it at a glance, search it later, copy the part that matters, and keep a written record of what was actually said.

Transcribe a voice message with Zap, step by step

Zap connects to your own WhatsApp number through linked-device pairing, so transcripts land right inside the same conversation. Once your number is paired:

1. Open the WhatsApp chat that has the voice note you want to read.
2. Make sure Zap is paired to that number — send /status in any chat to confirm it is active.
3. Play, or simply receive, the voice note. Zap detects the audio automatically.
4. Within a few seconds, a clean, punctuated transcript appears in the same chat, in the language that was spoken.
5. For audios longer than two minutes, Zap also returns a short bullet summary so you can skip the replay entirely.

What about other languages?

Zap transcribes more than 100 languages and detects the spoken language for you — there is nothing to set. If the note is in a language you do not read, you can also ask Zap to translate the transcript; the companion guide on translating a WhatsApp audio note walks through that in detail.

How accurate is it?

Transcription runs on hosted Whisper, which handles accents, background noise, and natural speech well. Clear audio in a quiet room is close to perfect; a noisy street or two people talking at once is harder, as it would be for any human typist. The transcript is yours: audio is processed in real time and discarded immediately after, so nothing is stored on our servers.

What does it cost?

There is no subscription. You pay $0.12 per minute of audio, billed in $0.02 for every started 10 seconds, from a prepaid wallet that never expires. A 30-second note costs about six cents, and new accounts start with free credit, so you can test it before you spend anything.
