Hey everyone so I'm having a difficult time trying to implement an audio playback. Here's the docs

So what I really want to do seems quite simple but came out to be very confusing where everything is suppose to go.

I want to be able to say a command. Alexa will respond will a little outputSpeech and then proceed to play a small audio track mp3 that I would provide. I don't mind uploading it locally(When I zip the files and import them into a lamda function) or using S3 Buckets SDK to stream the mp3 file. Which ever is easier for you guys.

Here's what I got so far.

With the codes below I'm able to get Alexa to respond to be voice and output a speech.

I'm only using the IntentRequest to reduce codes for you guys.

  • I'm going to say "Alexa open myApp and play my music"
  • "play my music" is the command i'm going to list as my utterance when I set up my skill in the alexa developer console
exports.handler = (event, context, callback) => {
    try {
        if (event.request.type === 'IntentRequest') {
            onIntent(event.request,
                event.session,
                (sessionAttributes, speechletResponse) => {
                    callback(null, buildResponse(sessionAttributes, speechletResponse));
                });
        }
    } catch (err) {
        callback(err);
    }
};


My function that will be called when the Intent request goes through

  • My intent name will be PlayMyMusic


function onIntent(intentRequest, session, callback) {
    console.log(`onIntent requestId=${intentRequest.requestId}, sessionId=${session.sessionId}`);

    const intent = intentRequest.intent;
    const intentName = intentRequest.intent.name;

    if (intentName === 'PlayMyMusic') {
        PlayMyMusic(intent, session, callback);
    } else if (intentName === 'AMAZON.StopIntent' || intentName === 'AMAZON.CancelIntent') {
        handleSessionEndRequest(callback);
    } else {
        throw new Error('Invalid intent');
    }
}


This is the output Message 

function PlayMyMusic(intent, session, callback) {

    const repromptText = null;
    const sessionAttributes = {};
    let shouldEndSession = true;
    let speechOutput = '';

        speechOutput = `I'm Alexa and I will output speech in this area. After I'm done talking I will play an audio track`;

    callback(sessionAttributes,
        buildSpeechletResponse(intent.name, speechOutput, repromptText, shouldEndSession));
}

This is my simple Intent Schema

{
  "intents": [
    {
      "intent": "PlayMyMusic"
    },
    {
      "intent": "AMAZON.HelpIntent"
   }
  ]
}

Sample Utterances

PlayMyMusic play my music


Everything works as of right now where Amazon can talk to me back and end the session.

How would I be able to have Amazon responds to me and then play some audio? The docs are kind of not working for me.

  • Where do I put the play directive? (AudioPlayer.Play)

    you can use SSML and add mp3 path at any https url and it will play song

    see this 

    Include the audio tag within your text-to-speech response within the speak tag. Alexa plays the MP3 at the specified point within the text to speech. For example:
<speak>
    Welcome to Car-Fu. 
    <audio src="soundbank://soundlibrary/transportation/amzn_sfx_car_accelerate_01" /> 
    You can order a ride, or request a fare estimate. 
    Which will it be?
</speak> 
When Alexa renders this response, it would sound like this:
Alexa: Welcome to Car-Fu.
(the specified amzn_sfx_car_accelerate_01.mp3 audio file plays)
Alexa: You can order a ride, or request a fare estimate. Which will
