Amazon Alexa无法识别号码槽

Question

Lets say i have this in my schema:

 {
  "slots": [
    {
      "name": "number",
      "type": "AMAZON.NUMBER"
    }
  ],
  "intent": "PriceMyProduct"
}

And these utterances:

PriceMyProduct price of {number}
PriceMyProduct {number} price

In my lambda function I have this intent handler

'PriceMyProduct': function(){
        var itemNumber = this.event.request.slots.number.value;
         //DO STUFF
 }

The problem is that "itemNumber" never picks up the number of the product, so it is always undefined.

I have tried doing stuff like "price of 133202" or "133923 price", but the number value is never picked up. What could be the problem?

Answer 1

Try changing name of your slot from "number" to let say "priceValue". Something like this:

{
  "slots": [
    {
      "name": "priceValue",
      "type": "AMAZON.NUMBER"
    }
  ],
  "intent": "PriceMyProduct"
}

Then update utterances like this:

PriceMyProduct price of {priceValue}
PriceMyProduct {priceValue} price

And in lambda use the new name:

'PriceMyProduct': function(){
    var itemNumber = this.event.request.slots.priceValue.value;
     //DO STUFF
 }

Reason: number seems to be a reserved name
