# setLanguages

> Replace all language configurations at once.

[ref-agentbase]: /docs/server-sdks/reference/typescript/agents/agent-base

[add-language]: /docs/server-sdks/reference/typescript/agents/agent-base/add-language

Replace all language configurations at once with a new array. Each element is passed
through [`addLanguage()`][add-language] internally.

## **Parameters**

**`languages`** `LanguageConfig[]` — required

Array of language configuration objects. Each object should include `name`, `code`,
and optionally `voice`, `engine`, `fillers`, `speechModel`, `functionFillers`, and
`params` (an engine-specific tuning dictionary, only emitted when non-empty).

---

## **Returns**

[`AgentBase`][ref-agentbase] -- Returns `this` for method chaining.

## **Example**

```typescript {5}
import { AgentBase } from '@signalwire/sdk';

const agent = new AgentBase({ name: 'support', route: '/support' });
agent.setPromptText('You are a helpful assistant.');
agent.setLanguages([
  { name: 'English', code: 'en-US', voice: 'rime.spore' },
  { name: 'Spanish', code: 'es-MX', voice: 'rime.luna' },
  { name: 'French', code: 'fr-FR', voice: 'rime.soleil' },
]);
await agent.serve();
```
