This role requires a female voice that projects focused, unwavering professional authority under high stress. Priscilla Nixon is the dedicated 911 Operator; her voice must remain steady, controlled, and measured, providing a stark, necessary contrast to the caller's chaos. She should sound like she is following protocol, maintaining a clear rhythm while asking for information and giving instructions. Her only break in composure comes right at the abrupt end, when she calls out sharply after the line disconnects.
