# Select a Voice and Customize

> Learn how to select and customize your agent voice

Phonely lets you select, test, and personalize the voice your AI agent uses during calls. You can choose from a library of professionally designed voices, filter them by language, gender, or accent, and even fine-tune their delivery for your use case.

Phonely allows you to clone a custom voice so your AI agent can sound more personalized or closely match your brand’s tone. More details on [how you can clone your voice here](/agent-design/voice/clone-voice).

From the agent design page, locate the choose a voice section. Click the voice button to open the Voice Library.

This brings up two main sections:

* **Featured Voices:** Curated, popular voices that showcase different styles and accents.
* **Explore All Voices:** A searchable, filterable list of every available voice.

Each voice card includes:

* A Play button to preview how it sounds.
* Tags showing its accent, gender, and supported languages.
* A heart icon to mark it as a favorite for quick access later.

Click **Select** to assign the voice to your AI agent. The selected voice will show a “Selected” badge under actions.

* **Multi-Lingual Support:** Toggle this settings on to enable the AI to speak and understand multiple languages seamlessy.

When done, click **Save Settings** to apply your customizations.

## Manage Voices

You can:

* [**Add New Voices**](/agent-design/voice/add-a-voice)**:** Use the **+ Add Voice** button to upload or import new voices from providers such as 11 Labs.
* **Mark Favorites:** Click the heart icon to save preferred voices.
* **View Usage Metrics:** Review voice usage metrics to understand call volume, duration, and overall AI voice consumption.

After customizing, your chosen voice appears at the top of the **Agent Design** screen as the active voice. This voice will be used for all calls made by your agent.
