Amazon Polly

Amazon Polly is a service that turns text into lifelike speech, allowing you to create applications that talk, and build entirely new categories of speech-enabled products. Amazon Polly is a Text-to-Speech service that uses advanced deep learning technologies to synthesize speech that sounds like a human voice.

With dozens of lifelike voices across a variety of languages, you can select the ideal voice and build speech-enabled applications that work in many different countries.

This is not a free service. It requires an Amazon AWS account.

• For the 1st 12 months, Amazon Polly includes 5 million characters per month for speech or speech mark requests, starting from your first request.
• After 12 months, or after you exceed 5 million characters in a month, Amazon Polly is priced at USD$4.00 per 1 million characters for speech or speech marks requests.
