Я пытаюсь использовать встроенные функции Amazon для запросов за пределами диапазона в моем навыке Custom Alexa. Alexa могла бы использовать для этого "AMAZON.FallbackIntent", я нашел здесь базовую настройку: https://developer.amazon.com/it/blogs/alexa/post/f6bb7c54-de0d-4abe-98c3-cf3fc75c32f8/how-to-add-fallbackintent-processing-to-your-alexa-skill
Эта возможность теперь доступна для всех локалей "en", во всяком случае после многочисленных попыток я создал "en-GB.json" и "en-US.json" с такой же структурой, как показано ниже:
"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": []
},
Все встроенные намерения работают нормально, за исключением резервного. Вот пример из фрагментов index.js для навыка:
const Alexa = require('ask-sdk');

После запуска навыка оно выполняет:
SpeechText
для которого я пытаюсь сказать, какая погода, навык игнорирует этот ввод и просто выполняет:
repromptText
а потом, если я снова запрошу погоду, он просто закроет навык ...
Как сделать так, чтобы это работало для моделей на английском языке?
