@aws-sdk/client-polly

What is @aws-sdk/client-polly?

@aws-sdk/client-polly is an AWS SDK for JavaScript package that allows developers to interact with Amazon Polly, a service that turns text into lifelike speech. This package provides a variety of functionalities to synthesize speech, manage lexicons, and retrieve information about available voices and speech synthesis tasks.

What are @aws-sdk/client-polly's main functionalities?

Synthesize Speech

This feature allows you to convert text into speech. The code sample demonstrates how to synthesize speech using the PollyClient and SynthesizeSpeechCommand classes.

const { PollyClient, SynthesizeSpeechCommand } = require('@aws-sdk/client-polly');
const client = new PollyClient({ region: 'us-west-2' });
const params = {
  OutputFormat: 'mp3',
  Text: 'Hello, world!',
  VoiceId: 'Joanna'
};
const command = new SynthesizeSpeechCommand(params);
client.send(command).then((data) => {
  // Handle the audio stream in data.AudioStream
}).catch((error) => {
  console.error(error);
});

List Voices

This feature allows you to retrieve a list of available voices. The code sample demonstrates how to list voices using the PollyClient and DescribeVoicesCommand classes.

const { PollyClient, DescribeVoicesCommand } = require('@aws-sdk/client-polly');
const client = new PollyClient({ region: 'us-west-2' });
const command = new DescribeVoicesCommand({});
client.send(command).then((data) => {
  console.log(data.Voices);
}).catch((error) => {
  console.error(error);
});

Manage Lexicons

This feature allows you to manage custom pronunciation lexicons. The code sample demonstrates how to list lexicons using the PollyClient and ListLexiconsCommand classes.

const { PollyClient, ListLexiconsCommand } = require('@aws-sdk/client-polly');
const client = new PollyClient({ region: 'us-west-2' });
const command = new ListLexiconsCommand({});
client.send(command).then((data) => {
  console.log(data.Lexicons);
}).catch((error) => {
  console.error(error);
});
