## Set up the backend If you haven't already done so, run `amplify init` inside your project and then `amplify add auth` (we recommend selecting the *default configuration*). Run `amplify add predictions` and select **Convert**. Then use the following answers: ```console ? What would you like to convert? (Use arrow keys) Translate text into a different language > Generate speech audio from text Transcribe text from audio ? Who should have access? Auth and Guest users ``` Now run `amplify push` which will generate your `aws-exports.js` and create resources in the cloud. You can now either add this to your backend or skip and add more features to your app. Services used: Amazon Polly ## Working with the API Generate an audio buffer for playback from a text input. ```javascript Predictions.convert({ textToSpeech: { source: { text: textToGenerateSpeech }, voiceId: "Amy" // default configured on aws-exports.js // list of different options are here https://docs.aws.amazon.com/polly/latest/dg/voicelist.html } }) .then(result => console.log({ result })) .catch(err => console.log({ err })); ```
