# addHint

> Add a single speech recognition hint to improve transcription accuracy.

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

Add a single speech recognition hint. Hints boost the automatic speech recognition
(ASR) engine's accuracy for specific words or phrases that may otherwise be
misrecognized -- such as product names, technical jargon, or uncommon proper nouns.

## **Parameters**

**`hint`** `string` — required

A word or phrase to boost recognition accuracy.

---

## **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.addHint('SignalWire');
await agent.serve();
```
