如何在Alexa Skill lambda函数中正确指定SSML?

我正在尝试制作一个Alexa技能,其中Alexa说的是用SSML标记的东西。我试图模仿这个repo中的例子,但我总是收到一个lambda响应

{
  ...
  "response": {
    "outputSpeech": {
      "type": "SSML",
      "ssml": "<speak> [object Object] </speak>"
    },
  ...
}

和Alexa字面上说&#34;对象&#34;。

这是我输入我的lambda函数(使用node.js):

var speechOutput = {
    type: "SSML",
    ssml: 'This <break time=\"0.3s\" /> is not working',
};

this.emit(':tellWithCard', speechOutput, SKILL_NAME, "ya best not repeat after me.")

像这样设置speechOutput也不起作用:

var speechOutput = {
    type: "SSML",
    ssml: 'This <break time=\"0.3s\" /> is not working',
};

<小时/> 编辑:

index.js

&#39;使用严格的&#39;;

var Alexa = require('alexa-sdk');

var APP_ID = "MY_ID_HERE";
var SKILL_NAME = "MY_SKILL_NAME";

exports.handler = function(event, context, callback) {
    var alexa = Alexa.handler(event, context);
    alexa.APP_ID = APP_ID;
    alexa.registerHandlers(handlers);
    alexa.execute();
};

var handlers = {
    'LaunchRequest': function () {
        this.emit('Speaketh');
    },
    'MyIntent': function () {
        this.emit('Speaketh');
    },
    'Speaketh': function () {
        var speechOutput = {
            type: "SSML",
            ssml: 'This <break time=\"0.3s\" /> is not working',
        };

        this.emit(':tellWithCard', speechOutput, SKILL_NAME, "some text here")
    }
};

任何人都知道我哪里出错了?

GitHub上的每个the alexa-sdk source code for response.js,代码中的speechOutput对象应该是一个字符串。 Response.js负责构建您尝试在代码中构建的响应对象:

this.handler.response = buildSpeechletResponse({
    sessionAttributes: this.attributes,
    output: getSSMLResponse(speechOutput),
    shouldEndSession: true
});

深入挖掘,buildSpeechletResponse()调用createSpeechObject(),它直接负责在Alexa Skills Kit响应中创建outputSpeech对象。

因此,对于没有高级SSML功能的简单响应,只需在:tell上发送一个字符串作为第一个参数,然后让alexa-sdk从那里处理它。

对于高级ssml功能(如暂停),请查看ssml-builder npm包。它允许您将响应内容包装在SSML中,而无需自己实现或硬编码SSML解析器。

使用示例:

var speech = new Speech();

speech.say('This is a test response & works great!');
speech.pause('100ms');
speech.say('How can I help you?');    
var speechOutput = speech.ssml(true);        
this.emit(':ask', speechOutput , speechOutput); 

此示例发出一个ask响应,其中语音输出和reprompt语音都设置为相同的值。 SSML Builder将正确解析&符号(这是SSML中的无效字符),并在两个说法语句之间暂停100ms暂停。

示例回复:

Alexa Skills Kit将针对以上代码发出以下response object

{
  "outputSpeech": {
    "type": "SSML",
    "ssml": "<speak> This is a test response and works great! <break time='100ms'/> How can I help you? </speak>"
  },
  "shouldEndSession": false,
  "reprompt": {
    "outputSpeech": {
      "type": "SSML",
      "ssml": "<speak> This is a test response and works great! <break time='100ms'/> How can I help you? </speak>"
    }
  }
}

这是一个老问题,但我最近遇到了类似的问题,希望能够提供一个不需要额外依赖的答案。

如上所述,'Speaketh': function () { var speechOutput = 'This <break time="0.3s" /> should work'; this.emit(':tellWithCard', speechOutput, SKILL_NAME, "some text here") } 假设是一个字符串,所以alexa说&#34;对象对象&#34;是因为它是一个json。

按以下方式尝试处理程序

{ 
  ...
  "response": {
    "outputSpeech": {
    "ssml": "<speak> This <break time=\"0.3s\" /> should work </speak>",
    "type": "SSML"
  },
  ...
}

返回此回复

 protocol  OrderSubItemTableDelegate {

     associatedtype cellType // cell type either vc1 or vc2

     static func tableViewDidSelectRowAt(object: cellType)
}

class VCCell1: UITableViewCell ,OrderSubItemTableDelegate {

    typealias cellType = VCCell1

    static func tableViewDidSelectRowAt(object: VCCell1) {

    }

}

您可以这样编写代码:

'BreakIntent':function(){
        var speechOutput = 'She is better known as <break time="3s" /> Champion';
        var reprompt = "How can I help?";
        this.response.speak(speechOutput);
        this.response.listen(reprompt);
        this.emit(":responseReady");
    },

我面临着同样的问题,可以通过这样编写代码来解决。
