## on\_agent\_speech()

Register a handler to receive a callback whenever the agent speaks. The event contains what the agent said and whether it was interrupted by the caller.

The `AgentSpeechEvent` is a pydantic model imported from `guava.events`:

```python
from guava.events import AgentSpeechEvent

class AgentSpeechEvent(BaseEvent):
    event_type: Literal["agent-speech"] = "agent-speech"
    utterance: str
    interrupted: bool = False
```
