Amazon Polly Voices available in Windows applications

[Amazon Polly](/polly/) is a service that turns text into lifelike speech. Today, we are excited to announce the release of Amazon Polly for Windows, an open-source engine that allows users to take advantage of Amazon Polly voices in SAPI-compliant Windows applications. SAPI (Speech Application Programming Interface) is a Microsoft Windows API that allows desktop applications to implement speech synthesis. When an application supports SAPI, it can access any of the installed SAPI voices to generate speech. Out of the box, Microsoft Windows provides one SAPI male and female voice that can be used in any supported voice application. With Amazon Polly for Windows, users can install over 50 additional voices across over 25 languages, paying only for what they use.
