`

`
const CFGPATH = "MY_AWS.json";
const { SayAgain, TtsPolly } = require("say-again");

var request = {
"api": "aws-polly",
"apiVersion": "v4",
"audioFormat": "mp3",
"voice": "Amy",
"language": "en-GB",
"text": "hello"
}

var v = new SayAgain(CFGPATH);
var res = await v.speak(request);
// {
// request,
// s3Key,
// response: {
// mime: "audio/mpeg",
// base64: "..."
// }
// }
`

To generate an MP3 file from the result:

`
var buf = Buffer.from(res.response.base64, 'base64');
fs.writeFileSync('hello.mp3', buf);
