# Voice & Language

> Customize your AI Agent’s voice, accent, and language to align with your brand and better engage your audience across global markets.

## Overview

Whether you’re using the thinkrr app directly or integrating with GHL, voice and language customization ensures your AI Agent speaks with the tone, personality, and language best suited to your audience. From accents to supported languages, thinkrr provides extensive configuration options for both outbound and inbound AI agents.

## Outbound Calling

<AccordionGroup>
  <Accordion title="thinkrr">
    <Steps>
      <Step>
        Start by creating a **Project**, which is required for any outbound calling. Refer to the [Projects & Scenarios](/Projects-and-scenarios) documentation for more information on creating **projects**.

        </Frame>
      </Step>

      <Step>
        Once your Project is set, create a **Campaign** where you define the AI Agent responsible for the outbound communication. Think of this as assigning a task to a virtual employee, including contact lists and call styles. See [**Campaign Management**](/Campaign-Management-f4bd929fa38e478f86180c93c36df7e4) for more.

We currently have **100 total agents** across **17 languages**:

* **English** – 43 agents
* **Spanish** – 7 agents
* **Portuguese** – 5 agents
* **Chinese** – 4 agents
* **Italian** – 4 agents

💡 **Tip:** Assign voice agents based on your audience. For example, use a **male Spanish (Mexico)** agent for Latin American outreach, or a **female British English** agent for UK-based clients. Matching the voice profile to your customer’s region or expectations helps improve engagement and trust.

## FAQs & Troubleshooting

### Audio Samples and Testing

    Some sample audios may be limited to English, but live calls use the configured language and voice.
