How do I play a Watson Text-to-Speech response through my speakers?

I am trying to add Text-to-Speech to a ChatBot on a web browser using NodeJS, where I want to show the text and to play the speech when I get a response.

I have searched and found the following example that creates a WAV file, which works good.

// Pipe the synthesized text to a file
text_to_speech.synthesize(params).pipe(fs.createWriteStream('output.wav'));

Instead of creating a file, how can I just play the response directly on my laptop speakers?

I battled with this for a while now. I was running in on my raspberry pi and was running into problems with the speaker solution.

The below worked for me.

var Sound = require('node-aplay');


var f =text_to_speech.synthesize(params).pipe(fs.createWriteStream('output.wav'));

f.on('finish', function () {

  new Sound('output.wav').play();

  console.log("Done");
});
