Let’s look at how the interaction works in the application. Both methods are exposed as RESTful web services through Amazon API Gateway. The application provides two methods – one for sending information about a new post, which should be converted into an MP3 file, and one for retrieving information about the post (including a link to the MP3 file stored in an S3 bucket). The Cloud automatically takes care of this, allowing us to focus on our application. It uses a serverless approach, which means that we don’t need to work with servers – no provisioning, no patching, no scaling. The following diagram shows the application architecture. For example, you can use the application to read recipes while you are preparing a meal, or news articles or books while you’re driving or riding a bike. We’ll use blog posts, but you can use any type of text.

The application has a simple user interface that accepts text in many different languages and then converts it to audio files which you can play from a web browser. In this blog post, we create a basic, serverless application that uses Amazon Polly to convert text to speech. Amazon Polly immediately returns the audio stream to your application so that your application can play it directly or store it in a standard audio file format such as an MP3. You simply send the text you want to convert into speech to the Amazon Polly API. There are no additional text-to-speech charges for using the speech.) And Polly is easy to use. (In other words, what you convert and save is yours.

You can cache and save Polly’s audio files for offline replay or redistribution.

In addition, Amazon Polly delivers the consistently fast response times required to support real-time, interactive dialog. It currently includes 47 lifelike voices in 24 languages, so you can select the ideal voice and build speech-enabled applications that work in many different countries. Amazon Polly is an Amazon AI service that uses advanced deep learning technologies to synthesize speech that sounds like a human voice.

It lets you create applications that talk naturally, enabling you to build entirely new categories of speech-enabled products.

Foreign words ( déjà vu), proper names ( François Hollande), slang ( ASAP, LOL), etc.Īmazon Polly provides speech synthesis functionality that overcomes those challenges, allowing you to focus on building applications that use text-to-speech instead of addressing interpretation challenges.Īmazon Polly turns text into lifelike speech.

In this example, similar parts of different words can be pronounced differently depending on the word and context.

Converting text to phonemes in languages with complex mapping, such as, in English, t ough, thr ough, th ough.

Disambiguating abbreviations, acronyms, and units: St., which can be expanded as street or saint. This presentation broadcasts live from Las Vegas.

Words that are written the same way, but that are pronounced differently: I live in Las Vegas.

A few common challenges for text-to-speech applications include: You can’t just assume that when an application reads each letter of a sentence the output will make sense.
