Node.js Amazon Polly to speaker example.

amazon-polly-speaker.js

// Load the SDK
const AWS = require('aws-sdk')
const Stream = require('stream')
const Speaker = require('speaker')

// Create an Polly client
const Polly = new AWS.Polly({
    signatureVersion: 'v4',
    region: 'us-east-1'
})

// Create the Speaker instance
const Player = new Speaker({
  channels: 1,
  bitDepth: 16,
  sampleRate: 16000
})

let params = {
    'Text': 'Hi, my name is @anaptfox.',
    'OutputFormat': 'pcm',
    'VoiceId': 'Kimberly'
}

Polly.synthesizeSpeech(params, (err, data) => {
    if (err) {
        console.log(err.code)
    } else if (data) {
        if (data.AudioStream instanceof Buffer) {
            // Initiate the source
            var bufferStream = new Stream.PassThrough()
            // convert AudioStream into a readable stream
            bufferStream.end(data.AudioStream)
            // Pipe into Player
            bufferStream.pipe(Player)
        }
    }
})

Hi, thanks for this! Just wondering, do you get "Illegal instruction: 4" in the console when running this? It works as expected but just wondering what's causing the error message...

@stuarttayler +1

Thanks for this it works but process is killed after the sentence :( Process finished with exit code 132 (interrupted by signal 4: SIGILL)

Process finished with exit code 132 (interrupted by signal 4: SIGILL)
Did anyone manage this?

The "Illegal instruction 4" and "code 132..." issues is a problem with the speaker node module. Read the comments section in my revised Gist which shows you how to fix that issue. Also it allows you to change voices and chain sentences.

How to stop the Player in middle?

how to include this in an nextjs typescript project ?
