The Amazon Chime SDK lets developers add real-time audio, video, screen-sharing, and messaging capabilities to their web or mobile applications. Amazon Polly is a service that turns text into lifelike speech. Starting today, the Amazon Chime SDK supports native integration with Amazon Polly, making it easy for builders to create applications that turn text and numerical data into lifelike speech and automatically plays the output to a caller.

This integration streamlines the development of voice self-service prompts since it eliminates the costly and time-consuming dependency on the professional voice recording. For example, you could build a voice order status application that prompts a caller to enter their order number, retrieves the order information from an external database, and then speaks the order ship date back to the caller. You can use Amazon Polly for calls to or from the public telephone network and for calls with on-premises telephone equipment using the Session Initiation Protocol (SIP).

This integration supports all available languages and voices in Amazon Polly. You can also choose either plain text or Speech Synthesis Markup Language (SSML) to enrich the generated speech by adding pauses, emphasizing certain words, or to change the speaking style. In addition, to help fine-tune the caller experience, developers can choose between the standard or neural text-to-speech (NTTS) engine for improved speech quality.

Amazon Polly for Amazon Chime SDK is available in the US-East (N. Virginia) and US-West (Oregon) AWS regions. There are no additional Amazon Chime SDK charges to use Amazon Polly. Regular Amazon Polly pricing applies.
