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**

<ParamField path="hint" type="str" required={true} toc={true}>
  A word or phrase to boost recognition accuracy.
</ParamField>

## **Returns**

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

## **Example**

```python {5}
from signalwire import AgentBase

agent = AgentBase(name="support", route="/support")
agent.set_prompt_text("You are a helpful assistant.")
agent.add_hint("SignalWire")
agent.serve()
```
