Amazon Polly is a service that turns texts into lifelike speech, allowing you to create applications that talk, and build entirely new categories of speech-enabled applications. Today, Amazon Polly is releasing a new feature, time-driven prosody, which automatically adjusts the speech rate based on a maximum allotted amount of time you define. 

This feature is beneficial for many use cases, especially when it comes to localization. For example, suppose you have US English speech embedded in your training video and want to localize this video into German. Let’s say you translate the text using Amazon Translate and voice it with Polly. It is essential that the localized German speech streams in corresponding frames of the video, so the German speech cannot be longer than the US English speech. You can use this new feature to more easily facilitate the dubbing process.

Try the new time-driven prosody feature through the Amazon Polly console, or visit the Amazon Polly documentation for more information about the Command Line Interface (CLI) and AWS SDKs. You can also read more about this feature on Jeff Barr’s Blog
