I'm trying to use the Amazon in-built functionality for out-of-bound queries on my Custom Alexa skill. Alexa could use the "AMAZON.FallbackIntent" for such, I've found the basic setup here: https://developer.amazon.com/it/blogs/alexa/post/f6bb7c54-de0d-4abe-98c3-cf3fc75c32f8/how-to-add-fallbackintent-handling-to-your-alexa-skill
This ability is now available to all "en" locales, anyhow after numerous attempts I've set up an "en-GB.json" and "en-US.json" with the same structure as follows:
"intents": [
{
"name": "AMAZON.FallbackIntent",
"samples": []
},
{
"name": "AMAZON.CancelIntent",
"samples": []
},
{
"name": "AMAZON.HelpIntent",
"samples": [
"I don't know",
"What can you do",
"What are you capable of",
"What is this",
"help"
]
},
{
"name": "AMAZON.StopIntent",
"samples": []
},
All in-built intents work just fine with the exception of the Fallback one. Here's a sample from the index.js snippets for the skill:
const Alexa = require('ask-sdk');
const dbHelper = require('./helpers/dbHelper');
const GENERAL_REPROMPT = "What would you like to do?";
const dynamoDBTableName = "movies";

)
.addErrorHandlers(ErrorHandler)
.withTableName(dynamoDBTableName)
.withAutoCreateTable(true)
.lambda();
After launching the skill, the skill executes the:
speechText
for which I try saying what's the weather, the skill ignores that input and just executes the:
repromptText
and then if I ask for weather again it just closes the skill...
How could I make this work for either english language models?
