Step 9: Use slot labels to display the order

The user can ask for a burger or burgers (in plural). Alan AI will capture the pronounced grammar form with p.ITEM.value and display this form in the cart in the app. To make sure we add both variants to the same line, let’s use the label field of a slot. In the slot label, you can provide any description to identify or classify the slot values.

To each slot value, add the tilde ~ character with a slot value in singular. Modify the updateOrder command to send p.ITEM.label, not p.ITEM.value:

Dialog script
const itemList = "pepperoni_~pepperoni|margherita_~margherita|burrito_~burrito|burger_~burger|taco_~taco|apple pie_~apple pie";

intent(`(I want|I will take|Add|) (a|an|) $(ITEM ${itemList}), (please|)`,
       `(I want|I will take|Add|) $(NUMBER) $(ITEM ${itemList}), (please|)`, p => {`Adding ${p.ITEM.value} for you`, 'Sure', 'Here you go');
    let number = p.NUMBER ? p.NUMBER.number : 1;
    // Sending the ITEM label instead of the ITEM value{command: 'updateOrder', item: p.ITEM.label, quantity: number});

Try ordering food with voice in the app. Alan AI will now add One burger and Five burgers to the same line in the cart.
