# Voices

> Browse and preview all available AI voices, assign a voice to an agent, or clone a voice for a custom sound.

## Open the Voices page

The **Voices** section is where you manage how your agents sound. From here, you can:

* Browse the **Voice Library** (ready-to-use voices)
* **Preview** voices before using them
* **Assign** a voice to a specific agent
* **Clone a voice** (so your agent can speak with a custom voice)

Go to the **Voices** section by clicking here: [Voices](https://app.callin.io/voices)

## Browse and preview voices (Try Voices)

By default, you’ll land on **Try Voices**. This is the **Voice Library**, where each row includes:

* A **Play** button to preview the voice
* The **voice name** plus a short style description (for example: “laid-back”, “reassuring”, “energetic”)
* **Details tags** like gender, language, and accent (for example: **Male**, **en**, **american**)
* An **Assign** action on the right to use that voice with an agent

You can also narrow down the list using:

* The **search bar** (search by name or accent)
* Filters such as **gender** and other available dropdowns (options can vary by account/plan)

> **Tip:** When previewing voices, use the same short script each time so it’s easy to compare.

> Example: “Hi! This is Maya from Lakeside Dental. I’m calling to confirm your appointment for Thursday at 3 PM.”

## Assign a voice to an agent

To make an agent speak with a specific voice:

1. In **Try Voices**, find the voice you want.
2. Click **Assign** on the right side of that voice.
3. In the **Assign Voice to Agent** window, select the agent you want to update.
4. Click **Assign** to confirm.

After you assign it, that agent will use the selected voice when speaking on calls.

> **Important:** You can change a voice later by assigning a different one. Voice assignment is typically set per agent (not global).

## Clone a voice (Clone Voice)

If you want a more custom sound (for a brand voice or a specific persona), use **Clone Voice**.

1. Open the **Clone Voice** tab.
2. Click **Clone Voice**.
3. In the form (shown as a “Voice Preview” window), fill in:
   * **Voice Name** (required)
   * **Description** (optional)
   * **Language** (required)
   * **Gender** (required)
4. Add a **Voice Sample** (required) using one of the options shown:
   * **Upload Audio**
   * **Record Voice**
5. Follow the on-screen steps to submit your sample. Once your cloned voice is created, it will appear under **Your Cloned Voices** and can be assigned like any other voice.

> **Common mistake:** Uploading a clip that’s too short or has background noise. Your clone will sound noticeably worse if the sample isn’t clean.

## Voice cloning guidelines and best practices

When recording or uploading your sample, follow these guidelines:

* Record in a **quiet environment** with minimal background noise
* **Speak clearly** at a natural pace
* For uploaded files, provide **at least 30 seconds** of continuous speech
* Maximum file size is **4MB**
* Supported languages include: **English, Italian, French, German, Portuguese, Spanish, Dutch, Arabic, and Hindi**

> **Important:** Only upload audio you have permission to use (for example, your own voice or a voice you’re licensed to use).
