Amazon Alexa

Amazon Alexa

1. first test

The skill is created with Custom and Alexa-Hosted options. the other way could be with an aws account on AWS console. using lambdas.

Testing

2. Second test Collect slots turn-by-turn

Code on

The sample on documents say

const speakOutput = `Thanks, I'll remember that you were born ${month} ${day} ${year}.`;

but don't work that way, after debuging find that it has to be changed by:

const CaptureBirthdayIntentHandler = {
    canHandle(handlerInput) {
        return Alexa.getRequestType(handlerInput.requestEnvelope) === 'IntentRequest'
            && Alexa.getIntentName(handlerInput.requestEnvelope) === 'CaptureBirthdayIntent';
    },
    handle(handlerInput) {
        const year = handlerInput.requestEnvelope.request.intent.slots.year.value;
        const month = handlerInput.requestEnvelope.request.intent.slots.month.value;
        const day = handlerInput.requestEnvelope.request.intent.slots.day.value;
        const speakOutput = `Thanks, I'll remember that you were born .`;
       
        return handlerInput.responseBuilder
            .speak(speakOutput.concat(`${month} ${day} ${year}`))
            //.reprompt('add a reprompt if you want to keep the session open for the user to respond')
            .getResponse();
    }
};

note: it seem that it is not totaly necesary, after other testing rounds, the intent has to been called a second time to respond like it suppouse to be.

Testing

3. Persisting data on S3

change the code of the intent cake walk like this as the documentation say

   // This sample demonstrates handling intents from an Alexa skill using the Alexa Skills Kit SDK (v2).
// Please visit https://alexa.design/cookbook for additional examples on implementing slots, dialog management,
// session persistence, api calls, and more.

3.1 Deleteing Persisted data.

Correction:  has been capture the day as "two" when it has to be "second" , that why on year appears like 21970. correcting and seen the data in S3, we have:

Crear un  layer en AWS console o alternativamente usar Alexa pero no contara con todas las posibilidades que se dan en AWS console

En AWS console add trigger Alexa Skills Kit. se habilita y se a add. ya tendriamos el skill y el trigger con el evento.

ARN amazon resourse name

al crear el skill teemos la opcion de Custom -> Provision your own (para AWS console) o Alexa hosted node.js

en module-1 copiar el json y index a donde depositemos el repo cloud en alexa
