Amazon Polly text-to-speech support in Acrobat Pro DC ?

AWS just released Amazon Polly for Windows, an open-source engine that allows users to take advantage of Amazon Polly voices in SAPI-compliant Windows applications

Are you going to implement it in Acrobat Pro DC ? I followed the instructions from the link above, but after installing their windows client I can't see any AWS voices in Acrobat options (Preferences -> Reading -> Default Voice)
