How Do Custom Slot Types Work?

Custom slot types work by mapping user inputs to predefined values within a skill. Here’s a step-by-step breakdown of how they function:

1. Define the Slot Type: Developers create a custom slot type by listing all possible values that a user might say.
2. Assign the Slot Type: The custom slot type is then assigned to a slot within an intent.
3. User Interaction: When a user interacts with the skill, Alexa checks the user’s input against the predefined values in the custom slot type.
4. Processing: Based on the match, Alexa processes the input and responds accordingly.

Example Scenario

Let’s say you’re developing a skill for a football betting app. You might create a custom slot type called TeamNames with values like “Manchester United,” “Liverpool,” “Chelsea,” etc. When a user says, “Place a bet on Manchester United,” Alexa can accurately identify “Manchester United” as a valid team name and proceed with the betting process.
