# Agent Settings: Voice

![Voice settings panel in the Edit Agent modal, showing the voice enablement toggle, the Voice and Voice call sub-tabs, three voice source cards (Browser, OpenAI, Google), and a voice picker](/images/docs/os/agent-settings/agent_settings_voice.webp)

## Overview

The Voice panel controls whether an agent can speak, which voice it speaks with, and how voice calls behave. Its header describes it simply: "Choose the voice your agent uses and how voice calls work." When voice is enabled, users can talk to the agent out loud and hear it reply, like a phone call.

The panel is split into two sub-tabs. The **Voice** sub-tab (documented on this page) selects the voice the agent uses to read out replies in chat, while the **Voice call** sub-tab configures how live voice calls behave. Voice calls run as real-time WebRTC sessions powered by LiveKit.

To reach this panel, open the **Edit Agent** modal for any agent, stay on the **Configurations** tab group, and select **Voice** in the left sidebar. The sidebar also lists Settings, LLM, Screen Share, Prompts, Skills, Safety, Privacy, and Disclaimers.

## Target Audience

**Administrator** | **Agent Builder**

## Settings Reference

#### Voice enablement toggle
The toggle at the top of the panel sits next to the text: "Let people talk to this agent out loud and hear it reply, like a phone call. When on, pick the voice and fine-tune how calls behave below." Turn it on to expose the voice and call options; the sub-tabs below let you pick the voice and adjust call behavior.

#### Voice / Voice call sub-tabs
Two pill-style sub-tabs switch between voice selection and call configuration. **Voice** covers "The voice your agent uses to read out replies in chat." **Voice call** covers call style, spoken language, provider, and call voice — see the Voice Call page for details.

#### Voice source
Three selectable cards choose where the agent's speech comes from:

- **Browser** — "Speak through the user's own device. No setup needed." Uses the built-in speech synthesis of the user's browser, so no voice picker appears for this source.
- **OpenAI** — "High-quality voices from OpenAI." Selecting this source reveals a searchable voice picker below.
- **Google** — "Natural-sounding voices from Google." Also reveals a searchable voice picker for Google voices.

The selected card is highlighted with a blue border (OpenAI in the screenshot).

#### Voice picker ("Select a voice")
When the OpenAI or Google source is selected, a **Voice** field appears with a "Select a voice" trigger. Clicking it opens a modal picker where you can search, browse, and preview voices before choosing one (see the Voice Selector page). Once a voice is saved, the trigger displays the currently selected voice, with an inline play button to preview it without opening the picker.

#### Save voice
The **Save voice** button persists your voice source and voice selection to the agent's settings. It is the save action for this sub-tab only; the Voice call sub-tab has its own Reset and Save controls.

## How to Use

#### Step 1: Open the Voice panel
Open the **Edit Agent** modal, keep the **Configurations** tab selected, and click **Voice** in the sidebar.

#### Step 2: Enable voice
Turn on the toggle at the top so people can talk to the agent out loud and hear it reply.

#### Step 3: Pick a voice source
On the **Voice** sub-tab, click one of the three source cards: **Browser** (no further setup), **OpenAI**, or **Google**.

#### Step 4: Select a voice
If you chose OpenAI or Google, click **Select a voice** to open the voice picker. Search or browse the list, press a play button to hear a sample, and click a voice to select it.

#### Step 5: Save
Click **Save voice**. To configure how calls themselves behave (call style, spoken language, call provider and voice), switch to the **Voice call** sub-tab.
