I have not seen a download for Speech API since Window XP, version 5.1. I think Win dows 10 is version 5.4. A Speech Platform softare was available for phones on a server scenario a few years ago, but not for desktop. I just use the buildt-in voices for Windows, like David.

Hi good people:
I've tried unsuccessfully all day to download the Microsoft speech
platform runtime SPK version 11 software, but with no success. When I
arrive at the page for the download, the software is not listed among
the files to be downloaded. Is there a software by that name: does
anyone have it, can anyone mail it to me.
Looking forward to reading from you.
I am Ibrahim Ajayi from Nigeria.
