How to automatically transcribe WhatsApp voice notes to text

The problem with long voice notes on WhatsApp

A customer sends you a 3-minute voice note explaining what they need. You have to listen to the whole thing, sometimes twice, to understand exactly what they're asking — and if you're handling several customers at once, those minutes add up fast. Worse still: an AI bot can't "listen" to audio directly, it needs text to understand it.

How automatic transcription works

When a voice note arrives, a speech-recognition model converts it to text in seconds, before anyone has to listen to it. That text gets saved in the chat history, and if you have an AI bot, it can read it and reply as if the customer had typed instead of spoken.

Real advantages of automatic transcription

How HeroChat solves this

HeroChat automatically transcribes every voice note you receive on WhatsApp, using speech-recognition AI. The text gets saved in the chat history, and the AI bot can read it and reply directly — without anyone having to manually listen to the audio, and without the bot going silent when it gets a voice message.

Frequently asked questions

Can the AI bot reply to a WhatsApp voice note?

Yes, if the audio is first automatically transcribed to text — that way the bot can read it and reply like any other message.

Can you search text inside already-transcribed voice notes?

Yes, once it's saved as text in the history, it can be searched like any other message.

Is the transcription 100% accurate?

Today's speech-recognition models are very accurate, though they can struggle with poor audio quality or heavy background noise.

Do I need to configure anything special to transcribe audios?

No, with HeroChat transcription happens automatically the moment the audio arrives, with no extra setup needed.
