S3-memoized Text-to-Speech adapter for sayings worth repeating. Default TTS is AWS Polly.
npm install --save say-again
Configure a SayAgain AWS configuration file
(e.g., MY_AWS.json)
cp test/data/aws-sample.json MY_AWS.json
Edit MY_AWS.json with your actual AWS credentials.
You can also configure AWS credentials using nodejs environment variables:
aws_config_regionaws_config_accessKeyIdaws_config_secretAccessKey
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": "<prosody rate=\"-30%\" pitch=\"-10%\">hello</prosody>"
}
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);
