Script and voice a 30-second audio ad that hits its offer before listeners tune out

Why this works

A 30-second ad slot is a hard constraint, not a suggestion, and most audio-ad prompts fail by describing a voice character in general terms while leaving pacing entirely to the model's default read speed, which routinely produces a script that either runs long or rushes the one line that actually sells anything. Marking the offer line explicitly and instructing a slight forward lean in pace around it works because Voice Design treats inline delivery instructions as local overrides on rhythm — it will pick up pace and add stress precisely where told rather than applying one flat energy level across the whole 30 seconds, which is what a generic "upbeat, energetic" instruction produces. Slowing down specifically on the call-to-action line is the opposite move for a good reason: contact details and URLs are exactly the information listeners miss when a read stays fast throughout, and background or car-radio listening (the actual context this format is built for) means the CTA is often the only line getting real attention. Choosing "a friendly local business owner, not a slick national-brand announcer" as the persona anchor also matters because it steers away from the default over-produced announcer cadence Voice Design tends toward, which reads as generic stock-ad filler rather than an ad a listener trusts.
