--- title: "Registering sentences" --- The conversation component handles incoming commands from the frontend and converts them to intents. It does this based on registered sentences. As a component, you can register sentences with the conversation component to allow it to be remote controlled. Refer to named slots by putting the slot name between curly braces: `{item}`. Use square brackets around (partial) words to mark them as optional. Example code: ```python async def async_setup(hass, config): hass.components.conversation.async_register('MyCoolIntent', [ 'I think that {object} is [very] cool', 'Nothing is cooler than {object}' ]) ``` If a sentence like "I think that beer is cool" comes in, the conversation component will generate an intent of type `MyCoolIntent` and with 1 slot, named `object` and value `beer`.
