# Voice settings

> Choose a voice, language, speaking speed, and response style for your Wave Runner agent.

Voice settings control how your agent sounds to callers.

Voice settings live on the **Model tab** of the agent editor, in the **Agent Settings** panel on the right.

## Voice

Wave Runner offers a library of voices across multiple languages and accents. Click the play button next to the voice dropdown to preview any voice before selecting it.

## Language

Set the **Language** dropdown before choosing a voice. The language setting also controls the speech-to-text transcription model.

Available languages: English, Spanish, Portuguese, French, German, Dutch, Italian, Hindi, Chinese, English & Spanish.

<Note>
  If your callers speak both English and Spanish, select **English & Spanish** to handle code-switching.
</Note>

## Speaking speed

The **Speed** slider runs from 0.5× to 2.0×. Default is 1.0×.

Slower speeds work well for complex instructions, legal disclosures, or callers who are non-native speakers. Faster speeds suit high-volume outbound calls with short, conversational exchanges.

<Tip>
  Small adjustments of ±0.2 make a noticeable difference. Stay close to 1.0× for most use cases.
</Tip>

## Response style

Response style controls how consistently the agent phrases its responses from call to call.

| Style        | Behavior                                  | Best for                                       |
| ------------ | ----------------------------------------- | ---------------------------------------------- |
| **Focused**  | Stays on-script. Minimal variation.       | Sales scripts, compliance, appointment booking |
| **Balanced** | Natural variation while staying on-topic. | Customer support, general inbound              |
| **Creative** | More expressive, less predictable.        | Brand personas that need personality           |

<Note>
  Focused is the right choice for most agents. It produces the most consistent, testable behavior.
</Note>

## Background sound

Background sound lives in the **Advanced tab** under **Call behavior**. It plays ambient audio during calls to reduce silence between responses.

| Option            | Description                  |
| ----------------- | ---------------------------- |
| Off               | No background audio          |
| Office — Standard | Moderate office ambience     |
| Office — Quiet    | Quieter background           |
| Office — Busy     | Active office ambience       |
| White Noise       | Neutral, environment-neutral |
