# Configuration

> Customize your LiveAvatar's appearance, voice, behavior, and interactivity

FULL Mode provides four customizable layers for your LiveAvatar session.

## Avatar (Visual Layer)

Defines what the avatar looks like. Choose from a wide selection of avatars, each with unique styles, appearances, and expressions.

Each avatar has a unique `avatar_id`. Browse available avatars through the [List Public Avatars](/api-reference/avatar/list-public-avatars) or [List User Avatars](/api-reference/avatar/list-user-avatars) endpoints.

## Voice (Audio Layer)

Defines what the avatar sounds like. Voices vary by gender, age, tone, and accent.

The `voice_settings` parameter enables fine-grained audio control for speed, style, and stability. See [Configuring Voice Settings](/docs/full-mode/voice-settings) for provider-specific options.

## Context (Cognitive Layer)

Defines how the avatar thinks and responds. The context layer controls:

* Available information and knowledge
* Response constraints and guardrails
* Personality traits
* Opening text (spoken at session start)
* Instructions for response generation

<Warning>
  If no context is supplied, the avatar operates in **restricted mode** — it will not respond to user input. User transcripts are still emitted, but the avatar can only repeat pre-set phrases.
</Warning>

## Interactivity Type (Conversational Layer)

Controls how user input is registered and when the avatar responds.

### Conversational (default)

The system manages conversation flow automatically based on speech pauses and user interruptions.

### Push-to-Talk

You control exactly when user input is registered by signaling start/stop events. VAD and ASR are disabled until you signal. See [Push-to-Talk](/docs/full-mode/push-to-talk) for details.

## Video Settings

These settings apply to both FULL and LITE modes.

### Quality

The `quality` parameter controls output resolution:

| Value            | Resolution |
| ---------------- | ---------- |
| `very_high`      | 1080p      |
| `high` (default) | 720p       |
| `medium`         | 480p       |
| `low`            | 360p       |

<Info>
  Higher resolution increases streaming latency. Use `high` or `medium` for most real-time applications.
</Info>

### Encoding

The `encoding` parameter controls the video codec: `VP8` or `H264`.
