I have a new TTS voice you can use with NVDA under SAPI5. You can go to jacksontts.fandom.com to learn more. You can also go to the extra voices page on NVDA's download page under Jackson TTS. It is only 5 dollars per person. It is very good with expression and long phrases. If I get enough people to buy it, I will add more voices to buy as well as upgrade my own.
