Trouble playing audio file

bugsounet

@sdetweil the problem is not there…
The problem is you can’t play a file when it’s not fully created!

2 solutions:
Make a promise
Or play the file when the file is created

sdetweil

@bugsounet ah yes good catch. I jumped to play()…

move the play() inside the callback on save()

players will be the next problem

bugsounet

just because sometime i'm kind... (my favorite sentence!)

Try this:

const gTTS = require('gtts');
var player = require('play-sound')(
  opts = {
    player: "mpg123" // use only `mpg123` for playing sounds
  }
);
var gtts = new gTTS('text to speak', 'es-es');

// main file player 
function playing (file) {
  player.play(file, (err) => {
    if (err) throw new Error(err)
  });
}

gtts.save('/tmp/hello.wav', (err, result) => {
  if(err) { throw new Error(err) }
  console.log('Success! start playing result.');
  // right ! sound file is created let's play it !
  playing("/tmp/hello.wav");
});

Notes:

You need to install mpg123 app with sudo apt-get install mpg123
I replace your play library by play-sound for better compatibility
Don’t forget to install this library npm install play-sound
You can see manual of play-sound library there

Thanks to both of you!
I have just tried the code and it works in a js file, but when I try to replicate this code in the MMirror I get the error that opts is not defined. Where do I have to declare opts?

I am writing this code in the node_helper file

@mZuil post your part of module code, I have do see what you have done ;)

@bugsounet It actually works!! :smiling_face_with_smiling_eyes: It happened because I was using the “use strict” directive, but without it, everything works as it should.
Wow, guys, you helped me a lot!! I will add you in the acknowledgement section of my final degree project hahaha :hugging_face:

@mZuil It’s better to add MagicMirror forum and not me, Thanks :)
because my signature says : I am not a reference in this forum

In all case i’m glade that works for you.
Happy use,
