What is Amazon Polly and how does it convert text into natural sounding speech?

Beginner

Answer

Amazon Polly is a text to speech service that uses advanced deep learning technology to turn written text into lifelike spoken audio in dozens of languages and voices, letting developers add voice capabilities such as reading articles aloud or providing voice responses in an application without needing any expertise in speech synthesis.
aws polly synthesize-speech --text 'Welcome to our application' --output-format mp3 --voice-id Joanna output.mp3
Real-world example A news application uses Polly to automatically generate an audio version of every published article, allowing users to listen to the news during their commute instead of only reading it on screen.
