Integration Steps

In order to use this functionality, you need to perform this three steps:


Record the voice

You need to have a record of the audio that you want to verify.

We can process recordings of different quality and formats, please check the media file requirements.


Send the voice for verification

You can send the voice for verification using our API. Please check the guide for performing an authenticity verification.

We will return the verification scores and subscores, which provide insights of whether the voice is synthetic, replayed, etc.

Once you have all the relevant data, you can decide which actions to take based on your business logic. Please check the verification thresholds page for reference and recommendations on interpreting the results. This are some common immediate actions to take, if the voice is deemed not real:

  • Directly end the call or communication, in order to protect the end user.
