Slots allows Alan to identify and retrieve important facts from the user’s speech. By having this data, the voice assistant can respond to the user’s request appropriately. For example, when building a weather voice assistant, you can capture the user’s location and date with slots so that the assistant can provide the correct forecast.

A command pattern can have a maximum of 5 slots, both user-defined and predefined.
