Voice AI Prompt Pack for Marketers

A curated set of tested prompts and system instructions for configuring real-time Voice AI agents that stay on-brand.

Create, optimize, and measure content that actually drives leads with Content Hub.

Real-time voice AI is still early days but in time it could become a primary surface area for how customers experience your brand.

This pack gives you a curated set of ready-to-use prompts and system instructions for configuring real-time Voice AI agents that stay on-brand — covering tone personas, interruption handling, escalation triggers, and multilingual fallback. Prompts are organized by use case: website visitor chat, post-purchase support, campaign lead qualification.

How to use this pack:

Each prompt in this pack is a system instruction — the set of rules you give a Voice AI agent before it ever speaks to a customer. Think of it as the briefing you’d give a new hire on their first day: here’s who we are, here’s how we talk, here’s what you do when things go sideways.

You’ll find prompts categorized into three sections:

  • Foundation prompts — brand voice, persona, and tone. Use these in every agent you build.
  • Behaviour prompts — how the agent handles interruptions, escalations, and silence. Drop these in on top of your foundation.
  • Use-case prompts — purpose-built instructions for three scenarios: website visitor chat, post-purchase support, and campaign lead qualification.

Anywhere you see [BRACKETS], replace with your own details. The more specific you are, the better the agent performs.

Section One

Foundation Prompts

Establish who your brand is before the agent says a single word.

Section Two

Behavior Prompts

Define how the agent handles the moments that separate a good voice experience from a frustrating one.

Section Three

Use-Case Prompts

Purpose-built system instructions for three specific scenarios. Stack these on top of your foundation and behaviour prompts.
Use Case A — Website Visitor Chat

For voice agents embedded on your website. The customer has arrived with a question or intent but you don’t yet know what it is.

Use Case B — Post-Purchase Support

For voice agents handling customers who have already bought. They’re coming in with a specific issue, question, or concern.

Use Case C — Campaign Lead Qualification

For voice agents handling inbound leads from a campaign. The prospect has shown intent — your job is to qualify them efficiently and move them to the right next step.

Improving Your Agent Over Time

The most valuable thing your team builds for your AI agent might be the "do-not-say" list. Every batch of calls will teach you something new to ban. 

After every week of calls, ask:

  • What did the agent say that made you wince?
  • Where did customers get frustrated or confused?
  • What question came up that the agent couldn’t handle well?

Add the answers to your do-not-say list and your scope definition. The prompts in this pack are the starting point. Your own call data is what makes them sharp.
