Amazon Polly

Amazon Polly turns text into lifelike speech using deep learning to create applications that talk.

Polly leverages advanced Neural Text-to-Speech (NTTS) technology to deliver high-quality human voices across 30+ languages. It offers a diverse portfolio of dozens of lifelike voices (including brand-specific custom voices) to synthesize speech for automated phone systems, news readers, and e-learning platforms. Developers use simple API calls to convert text into standard audio formats like MP3 or OGG, benefiting from low latency and a pay-as-you-go model that scales from small apps to global enterprise workflows.
