Amazon Polly is a text-to-speech software solution offered through Amazon Web Services, leveraging artificial intelligence and deep learning technologies. It transforms written text into speech, providing a variety of tones, styles, and pronunciations in multiple languages. Users can further customize the output voice by adjusting parameters such as loudness, pitch, and frequency using Speech Synthesis Markup Language tags, delivering a more human-like experience suitable for diverse applications.

This platform generates metadata that enriches word and sound descriptions, enhancing the creation of interactive elements such as animations paired with human voices. It supports various audio formats, including MP3 and OGG, and can be accessed through an API, AWS management console, or command line interface. Amazon Polly also includes features like lexicons for pronunciation adjustment and the ability to create unique brand voices, ensuring a tailored audio experience for users across different age groups and genders.
