Alexa，做笔记并通过邮件发送

Question

我想学习编写 Alexa Skills，所以我觉得一个 Skill，可以记录用户的语音并写下来，稍后通过邮件发送给他，会很酷。

我设法让用户启动了技能，但我不知道如何保存用户的"notes"。我在 google 上没有找到任何东西，所以我试着在这里问一下。

Answer 1

到今天为止，这个用例不能用技能开发。没有 API 只允许捕获原始用户或语音识别输入。一项技能接收语音识别和自然语言理解的结果，表示为 Intent 和一组实体。

Answer 2

我设法意识到了我的问题。这是我的解决方案： Intent（表述为德语，但槽 {NoteInput} 很重要）

{
"interactionModel": {
    "languageModel": {
        "invocationName": "mail notes",
        "intents": [
            {
                "name": "AMAZON.CancelIntent",
                "samples": []
            },
            {
                "name": "AMAZON.HelpIntent",
                "samples": []
            },
            {
                "name": "AMAZON.StopIntent",
                "samples": []
            },
            {
                "name": "noteIntent",
                "slots": [
                    {
                        "name": "NoteInput",
                        "type": "AMAZON.SearchQuery",
                        "samples": [
                            "notiere {NoteInput}",
                            "{NoteInput}"
                        ]
                    }
                ],
                "samples": [
                    "und schreibe auf {NoteInput}",
                    "und notiere {NoteInput}",
                    "notiere {NoteInput}",
                    "sende mir folgendes",
                    "und schreib auf",
                    "und notiere",
                    "notiere",
                    "und schreib mit",
                    "schreib mit",
                    "schreib auf"
                ]
            }
        ]
    },
    "dialog": {
        "intents": [
            {
                "name": "noteIntent",
                "confirmationRequired": false,
                "prompts": {},
                "slots": [
                    {
                        "name": "NoteInput",
                        "type": "AMAZON.SearchQuery",
                        "confirmationRequired": false,
                        "elicitationRequired": true,
                        "prompts": {
                            "elicitation": "Elicit.Slot.61384016725.485372519591"
                        }
                    }
                ]
            }
        ]
    },
    "prompts": [
        {
            "id": "Elicit.Slot.61384016725.485372519591",
            "variations": [
                {
                    "type": "PlainText",
                    "value": "Sehr wohl, ich trage zu protokoll"
                },
                {
                    "type": "PlainText",
                    "value": "Gerne, ich notiere"
                },
                {
                    "type": "PlainText",
                    "value": "Sehr wohl, ich notiere"
                },
                {
                    "type": "PlainText",
                    "value": "Gerne, ich schreibe mit"
                }
            ]
        }
}

}

如您所见，插槽 {NoteInput} 的插槽类型为 AMAZON.SearchQuery。这将导致 Alexa 简单地传输 Speech-to-Text。

Lambda 函数中的处理程序如下所示：

 const inProgressNoteIntentHandler = {
   canHandle(handlerInput) {
     const request = handlerInput.requestEnvelope.request;
    return request.type === 'IntentRequest'
      && request.intent.name === 'noteIntent'
      && request.dialogState !== 'COMPLETED' ;
  },handle(handlerInput) {
     const currentIntent = handlerInput.requestEnvelope.request.intent;
     return handlerInput.responseBuilder
      .addDelegateDirective(currentIntent)
      .getResponse();

  }
};

const completeNoteIntentHandler = {
  canHandle(handlerInput) {
    return handlerInput.requestEnvelope.request.type === 'IntentRequest'
      && handlerInput.requestEnvelope.request.intent.name === 'noteIntent';
  },handle(handlerInput) {
    const filledSlots = handlerInput.requestEnvelope.request.intent.slots;
    const slotValues = getSlotValues(filledSlots);
    console.log("Folgende Slots im noteIntent " + slotValues.NoteInput.synonym);


      noteArr.push(slotValues.NoteInput.synonym);
      console.log(noteArr.toString());



      return handlerInput.responseBuilder
      .speak("Ok, ich habe " +slotValues.NoteInput.synonym+ " notiert.")
      .getResponse();

  },


};

您需要此函数来获取插槽的值：

function getSlotValue(slot){
    let value = slot.value;
    let resolution = (slot.resolutions && slot.resolutions.resolutionsPerAuthority && slot.resolutions.resolutionsPerAuthority.length > 0) ? slot.resolutions.resolutionsPerAuthority[0] : null;
    if(resolution && resolution.status.code == 'ER_SUCCESS_MATCH'){
        let resolutionValue = resolution.values[0].value;
        value = resolutionValue.name;
    }
    return value;
}
