Shapes exactly how your agent talks, scripts, tone, and guardrails, so it stays on-brand and on-policy on every call.

- Brand Tone
- Approved Scripts
- Knowledge Base
- Escalation Rules
- Department Routing
- Safety Guardrails

Every call: On-brand, on-policy — your scripts, tone, and guardrails

## When the agent goes off-script and off-brand

AI voice agent customization puts you in control: define the answers, personality, and rules for your agent with AI custom responses, custom scripts for your common questions, a tone that matches your brand, and guardrails that keep it safe on sensitive topics.

- Off-the-shelf scripts don't sound anything like your business
- The agent answers common questions in ways you'd never approve
- There's no guardrail to keep it off sensitive or risky topics
- Each team wants the agent to say things its own way
- Updating what the agent says means waiting on someone else

## What you can shape on your agent

- **Custom scripts** — Define answers and knowledge for the questions you hear most.
- **Tone & brand control** — Tune the agent's personality to match your business.
- **Safety guardrails** — Keep the agent on-policy for sensitive or out-of-scope topics.

## What are customizable AI responses?

Customizable responses put you in control of exactly how your AI voice agent talks and behaves, from its scripts and tone to its guardrails.

It's trained on your approved knowledge, policies, and FAQs, tuned to your brand's tone, and bounded by rules you set, greetings, qualification questions, appointment logic, escalation triggers, working hours, department routing, and guardrails for sensitive topics. The result is an agent that sounds like your team and stays on-message and on-policy on every call, not a generic bot.

- Trained on your approved answers and policies
- Tone and personality matched to your brand
- Escalation, routing, and hours set by you
- Guardrails keep sensitive topics on-policy

## Custom voice AI: what you can change, and what you should not

The phrase covers two quite different things. A custom AI voice generator clones or synthesises a particular voice. Custom AI voice agents are about behaviour: what the agent says, what it asks, what it refuses, and when it hands over. The second matters far more to a caller than the first, and it is the one most buyers spend the least time on.

- **Script and behaviour** — This is where you create AI voice agent responses that match how your team already answers: the greeting, the order questions get asked in, the phrasing your callers expect. Most of the perceived quality of an agent comes from here rather than from the voice model.
- **Voice and persona** — Custom voice AI in the narrow sense: accent, pace, warmth, how it handles a name it has not seen before. A custom AI voice generator can match a brand voice closely, although callers reliably care more about being understood than about timbre.
- **Boundaries** — To tailor AI voice agent behaviour properly you have to decide what it must never attempt. Prices it cannot quote, advice it cannot give, promises it cannot make. Written down before launch, this is a short document. Discovered afterwards, it is an incident.

## What you can customize

- **Custom Greetings** — Opens every call in your business name and style.
- **Brand Tone & Voice** — Tunes personality from warm and casual to crisp and formal.
- **Approved Scripts & FAQs** — Loads your vetted answers for the questions you hear most.
- **Escalation Rules** — Defines exactly when and how the agent hands off to a human.
- **Department Routing** — Sends each call type down its own path and script.
- **Safety Guardrails** — Keeps the agent on-policy for sensitive or out-of-scope topics.

## How we build your agent's scripts and rules

- **Step 1. Map your call types** — We review the calls, FAQs, and rules your agent needs.
- **Step 2. Build the knowledge base** — Approved answers, tone, and scripts are loaded in.
- **Step 3. Define the rules** — Escalation, routing, and guardrails are set to your policy.
- **Step 4. Test, launch, refine** — We simulate calls, go live, and tune from real conversations.

## What customization means for your business

- **Consistent Experience** — Every caller hears the same on-brand answers.
- **Brand Control** — The agent sounds like your team, not a generic bot.
- **Fewer Wrong Answers** — Approved scripts keep responses accurate.
- **Stronger Compliance** — Guardrails keep sensitive topics on-policy.
- **Faster Handling** — Tuned scripts resolve calls more efficiently.
- **Easier Scaling** — Update once and every call reflects it.

## Customized responses on real calls

## Control every part of the conversation

From the first word to the fallback, you decide how the agent behaves. Set it once, update it anytime, and it applies on every call.

## Customization FAQs

### How much control do we have over what the agent says?

A lot. You shape the scripts, the personality, and the rules, from how it greets callers to how it handles your most common questions, so it speaks the way you want.

### Can we write custom answers for our common questions?

Yes. We load your approved answers and knowledge into the agent, so the questions you hear most get accurate, on-message responses every time.

### Can we set the agent's tone and personality?

Yes. You tune the voice and personality to match your brand, warm and casual or crisp and professional, so it sounds like your team, not a generic bot.

### Can we restrict topics the agent shouldn't handle?

Yes. Guardrails keep the agent on-policy for sensitive or out-of-scope topics, steering it to a safe response or a human handoff instead of improvising.

### How do we update responses after launch?

Responses aren't frozen at go-live. As your business changes, we update scripts, answers, and guardrails so the agent keeps pace with how you operate.

### Can different scripts apply to different call types?

Yes. Inbound reception, outbound follow-ups, and specific campaigns can each have their own scripts and tone, so every call type is handled the right way.
