Add support for Function Calling⚡️

[uezo]

Use chat_processor.add_function to use ChatGPT function calling. In this example, get_weather will be called autonomously.

# Add function
async def get_weather(location: str):
    await asyncio.sleep(1.0)
    return {"weather": "sunny partly cloudy", "temperature": 23.4}

app.chat_processor.add_function(
    name="get_weather",
    description="Get the current weather in a given location",
    parameters={
        "type": "object",
        "properties": {
            "location": {
                "type": "string"
            }
        }
    },
    func=get_weather
)

And, after get_weather called, message to get voice response will be sent to ChatGPT internally.

{
    "role": "function",
    "content": "{\"weather\": \"sunny partly cloudy\", \"temperature\": 23.4}",
    "name": "get_weather"
}
