Voice Configuration

Pick a voice, design a caller persona, and write a purpose that makes calls sound right.

Picking a voice

NovaVoxx offers a curated set of natural-sounding voices. Each has a different tone and feel — try a few before committing, since what sounds fine on a demo page can feel wrong in context.

Rules of thumb:

  • Match the voice to the persona you are projecting. A casual, warm voice does not match a "senior financial advisor" bio.
  • Test on real phone audio if you can. Telephony compresses voices and emphasizes some characteristics.

Caller persona

Three fields make up the persona:

  • Caller name — a real first name, short enough to say in one breath.
  • Caller organization — the exact name your customers recognize you by.
  • Caller bio — three to five sentences explaining who the caller is and why they are calling. This is the most important input.

See the full persona design guide for examples.

Purpose and expected output

Purpose is what the call is about. Expected output is what "success" looks like. These two fields are what the AI grounds every response in, so the more specific and concrete, the better.

Good purpose: "Following up with lapsed donors who have not given in 12 months. Reminding them of past gifts and asking if they would like to renew their support at any amount."

Weak purpose: "Donor outreach."
