Teach Thomas your voice/Choose a starting voice

Step 1 of 4

Choose a starting voice

Pick a built-in voice preset as your starting point.

Head to Voice & Style in the sidebar. At the top of the page, you'll see a row of voice pills — these are your starting points.

The Voice & Style page showing five built-in voice presets as pills: Thomas, Elizabeth, Jack, Sarah, and Alexis
Each preset gives Thomas a different personality

Thomas comes with five built-in voice presets:

  • Thomas — warm, approachable, and gently authoritative
  • Elizabeth — polished and professional with quiet confidence
  • Jack — energetic and direct, gets to the point
  • Sarah — conversational and encouraging, like a trusted friend
  • Alexis — creative and expressive, with a distinctive flair

Click on any preset to select it. The preview pane on the right will immediately show you a sample of how Thomas writes in that voice.

Don't overthink this choice. You're picking a starting point, not a final answer. In the next step, you'll fine-tune the tone with sliders, and you can always switch presets later.

If you've already created custom voices, they'll appear here too, along with a + button to create a new one from scratch.

Once you've picked a starting voice, move on to adjusting the tone.
