I've just discovered that my excellent but vintage text-to-speech MindMaker, TextAssist 4.0 works in Windows 10; all you have to do is to highlight and copy the desired text, paste it into a blank Microsoft Office Word 2003 (or newer version) .rtf, .txt, or .doc file window, and it plays the text. BTW, I have my own complete purchased download copy of MindMaker TextAssist 4.0, but it does not seem to be available anywhere as a download anymore.
This may be a downloadable link, but I did not join in order to test it;https://textassist.s...ftware.informer.com/
It may be abandonware by now.
When I clicked on the big rectangular green 'Download' button, it gave me this pop-up mssg; 'Would you like to install Software Informer Client and receive up-to-date information about TextAssist and other programs?'
I really feel chary of the words; 'install Software Informer Client', so I left it alone.
