polly-tts is a module that uses amazon polly for providing text to speech using the aws
As it uses EcmasScript 2015 code it will probably not work with older Node Versions.
For more information regarding polly see http://docs.aws.amazon.com/polly/latest/dg/how-text-to-speech-works.html

A simple example how to use this module.
let fs = require('fs');
let Polly = require('polly-tts');
let polly = new Polly();
let options = {
text: 'Hallo'
};
let fileStream = fs.createWriteStream('polly-tts.mp3');
polly.textToSpeech( options, ( err, audioStream ) => {
if( err ) {
return console.log(err.message);
}
audioStream.pipe(fileStream);
});
Create a new Class of the module. You can give an optional credentials Object with the class - otherwise it will be taken from process.env see aws4.
{ accessKeyId: 'YOUR-KEY', secretAccessKey: 'YOUR-SECRET-KEY' }
request text to speech options & callback are required options can look like: (optional value examples are the default values)
let options = {
text: 'some text to speech', // if textType is ssml, than here needs to be the ssml string
textType: "text, // marks if it is ssml, text etc. - optional
region: "eu-west-1", // aws region - optional
voiceId: "Vicki", // Polly Voice -> also determines the language - optional
sampleRate: 22050, // optional
outputFormat: "mp3" // all polly output formats like mp3, pcm etc. - optional
};
let callback = ( err, audioStream ) {
// err is an NodeJs Error
// audioStream is the response from the https module
}
