Voice creation methodology

Step 1

Step 2

Step 3

Specification of the voice

In close collaboration with the client, Voxygen qualifies the characteristics of the digital voice with a view to casting the choice of voice talent. We draw on interaction data from the Client's operational services and on the use cases envisaged. We then define the guidelines for the voice that will best embody the brand's values:

  • gender
  • age
  • timbre,
  • tone
  • expressiveness

Casting et recording

Based on the characteristics of the voice, a casting is organised to propose speakers to the client on the basis of:

  • a casting script
  • an evaluation grid

Once the choice has been validated and the contractual conditions established, we proceed with the studio recording.


Voice creation and delivery

From the recordings we learn an AI model of the voice using machine learning.

The voice is personalised and includes:

  • personalised lexicons
  • customer-specific pronunciation rules.


Once tested, the voice is delivered to the customer for acceptance. During this phase we provide :

  • an acceptance corpus
  • a free Voxygen Studio license
  • advice and expertise in adjusting the voice.
