Vivienne Vance

Before: Zephyr

After

Instructions:

A middle-aged woman with a thick French Canadian accent. She speaks with clarity and a professional, formal tone, at a fast-talking, energetic pace.

Sample Text:

"Bonjour, and welcome! Let’s streamline your goals, energize your workflow, and elevate results—because time is precious and excellence is non-negotiable"

Coral Dramatic

Before: Coral

After

Instructions:

A young adult female voice. A low, hushed, and suspenseful tone, conveying tension and intrigue. The delivery is deeply serious and mysterious, with an undercurrent of unease. A slow, deliberate pace, pausing slightly after key moments. The emotion is restrained yet intense.

Sample Text:

"Evelyn steadied her breath—tonight felt different. The danger felt personal. Somewhere nearby, hidden eyes watched her every move. Waiting. Planning. Knowing her next step."
