  • Helpful for Businesses − Businesses can use Polly's service since simple text message delivery is essential for reaching numerous audiences promptly in the workplace. The service is typically used to synthesize speech-impaired people's natural-sounding voices.

How can the Amazon Polly TTS Service be installed?

You must execute a sequence of commands with a bootstrap package to install Polly's TTS Service on your machine. To make the TTS service compatible with the Amazon Elastic Compute Cloud, bootstrap must run. To do this, go to AWS CodeStar, click "Add a New Service," and then choose the necessary bootstrap service.

You must download the AWS plugin for Windows to install Amazon Polly on Windows. Additionally, you must run the AmazonPollyForWindowsSetup.exe file after unzipping the downloaded folder to run the program. Then, you can change your system's speech settings using the control panel. You may carry out similar operations on iOS and other operating systems.

How does Amazon Polly work?

Providing input, analyzing the data, and converting the text information into an audio format are the three simple stages that makeup Amazon Polly's operation. The user is expected to supply the desired text material needed to synthesize into speech and choose between Natural Text-to-Speech (NTTS) and Standard Text-to-Speech (TTS) as the best speech type, along with the other selection of an appropriate audio format. The data is subsequently transformed into a "high-quality spoken audio stream" by the algorithm.

Let's clarify the process that was just mentioned in more detail −

  • Giving the necessary Input− As a user, you must give the speech you want to turn into an audio format with the desired content. Both plain text documents and SSML (Speech Synthesis Markup Language) files can be used as the input content format. As it provides for control of pronunciation, loudness, pitch, speech rate, and other elements of speech, the SSML input format is advised.

  • Choosing between the voices− After giving the program the necessary content, you are given the option to select from among the several voice sets and languages that Amazon Polly supports. The program offers various voices and languages choice, including bilingual voice formats for both Hindi and English.

    The audio can be synthesized in either a female or male voice for most languages. Before starting a speech synthesis process, all you need to do is specify the voice ID. Amazon Polly converts the text into speech after recognizing the ID. Notably, text translation cannot be done with Amazon Polly. The speech will be in the same language as the text.

  • Output from Amazon Polly Text-to-Speech− After a successful conversion, you can extract the output audio stream in the audio format of your choice. Polly supports multiple audio formats. Therefore, if you need your audio content in an MP3, MP4, PCM, or another format, you must choose from the program's several sets of audio formats.


The current world solution for all text-enabled talks is AWS Amazon Polly. Polly's text-to-speech service offers the customer a personalized experience with its automated, lifelike voices and choice of several widely accepted languages. It increases the learning experience and makes the content more scalable and accessible to the audience.
