Check a recording or video

Share it from your recordings, photos, files or email. Riviera shows you exactly where it heard the signs, and you can play that part yourself.

Listen live

Hold your phone near the voice, like a call on speaker or a video call. The answer updates about once a second, and a calm verdict appears after a few seconds of steady evidence.

Phones don’t let apps listen in on their own calls, so hold Riviera near another phone on speaker.

How it works

Three steps, then you decide

  1. 1

    Share it, or tap Record

    Share a recording or video to Riviera from another app. Or hold your phone near the voice and tap Record.

  2. 2

    Riviera listens

    Riviera sends the sound, over an encrypted connection, through Riviera’s server to our back-end service partner, which listens for the signs of an AI-generated voice.

  3. 3

    You listen too

    You see what Riviera found, and where. Play that part and judge for yourself.

Who it’s for

For the moments a voice gives you pause

Riviera is for everyday moments when something doesn’t sit right:

  • A call that sounds like someone you love, asking for money.
  • A voice message that doesn’t sound quite like them.
  • A clip you want to check before you share it.
  • A family member who isn’t sure what they heard, and wants to check it with you.

There’s no account to make. Share the recording, or hold your phone near the voice, and listen to what Riviera points to, on your own or with someone you trust.

What a result means

Four answers, in plain words

A finished check gives one of these four answers. Each one is a starting point for your own ears, not the last word.

This voice is probably AI-generated
Riviera heard AI-sounding speech long enough to say so, and shows you where. Play that part and listen.
We're not sure
Something sounded AI-made, but not for long enough to say so.
No sign of an AI voice
Riviera didn’t find any sustained AI-sounding speech. That isn’t a promise the voice is real.
Not enough speech to check
Too short or too quiet. Try a few seconds of someone talking.

Your privacy

To check a voice, Riviera sends the sound over an encrypted connection through Riviera’s server to our back-end service partner, which may keep it for a limited time. Read exactly what happens

A result is evidence, not proof. If you’re in doubt, ask someone you trust for help.
