## set_persona()

`call.set_persona()` is deliberately minimal. Give it the organization name and let the agent figure out the tone. You don't need to specify a voice style, a greeting template, or a list of prohibited phrases — Guava's defaults are professional and natural.

### Signature

```
call.set_persona(
    organization_name: str | None = None,
    agent_name: str | None = None,
    agent_purpose: str | None = None,
    voice: str | None = None,
)
```

### Parameters

| Parameter          | Type          | Default | Description                                                                                     |
|--------------------|---------------|---------|-------------------------------------------------------------------------------------------------|
| organization_name   | str \| None  | —       | The organization the agent represents. Used in introductions.                                  |
| agent_name          | str \| None  | —       | The agent's first name. Defaults to a generic 'assistant' style.                              |
| agent_purpose       | str \| None  | —       | A sentence describing why the agent is calling. Sets the LLM's operating context.              |
| voice               | str \| None  | "grace"| The TTS voice to use. Options: "grace" (southern female) or "jack" (British male).        |

### Example

```
call.set_persona(
    organization_name="Bright Smile Dental",
    agent_name="Alex",
    agent_purpose="You are calling patients to help them schedule and confirm dental appointments",
    voice="grace",
)
```

**Tip:** Include the contact's name in `agent_purpose` to help the agent personalize the conversation naturally.
