About Amazon Polly
Amazon Polly is a fully-managed AWS cloud service that uses deep learning to convert text such as articles, web pages, and PDFs into lifelike spoken audio via an API. It offers 100+ neural and standard voices across 40+ languages and variants, with SSML tags and custom lexicons to control pronunciation, emphasis, intonation, and style. Output can be streamed in real time or saved to standard audio files like MP3 and OGG for use in speech-enabled applications.
