# Voice-only mode

> Skip the avatar - let Clara speak over a pulsing visualizer for fast, low-bandwidth, voice-first conversations.

Voice-only mode replaces the avatar with an audio visualizer that pulses with Clara's speech. The conversation pipeline is identical - only the visual layer changes - and sessions get faster and lighter.

## When to use voice-only

| Scenario                       | Why voice-only wins                           |
| ------------------------------ | --------------------------------------------- |
| Fast, phone-like conversations | Feels natural without video overhead          |
| Low-bandwidth visitors         | A fraction of avatar video traffic            |
| Latency-sensitive flows        | Saves 50–100 ms of pipeline latency           |
| Brand-forward experiences      | Your logo and accent color carry the identity |
| Mobile web                     | Lighter sessions on constrained devices       |

## Visualizer variants

Six built-in visualizers react to Clara's voice in real time:

| Variant  | Style                                   |
| -------- | --------------------------------------- |
| `aura`   | Soft glowing halo                       |
| `bar`    | Vertical audio-meter bars               |
| `grid`   | Grid of pulsing cells                   |
| `radial` | Concentric circles that react to volume |
| `wave`   | Flowing horizontal waveform             |
| `earth`  | Rotating globe animation                |

## Setting up voice-only

1. Open the agent's settings and go to the **Avatar** tab.
2. Toggle **Voice-only mode** on.
3. Pick a **visualizer variant**.
4. Set an **accent color** - all variants pulse in it.
5. Optionally add your **company logo** (centered inside the visualizer) and enable a custom background scene.
6. Save. The mode applies everywhere the agent is embedded, on the next session.

## Best practices

* Match the variant to your brand tone - `aura` reads premium, `bar` reads technical, `earth` reads exploratory
* Choose a bold accent color so the visualizer is visible on any background
* Add your company logo: without a face, the logo becomes the visual identity
* Test on mobile - most voice-only traffic lands there

<Note>
  Voice-only is a render mode, not a separate agent. Your Clara agent keeps the same knowledge base, qualifying questions, and booking connections in either mode.
