This is possibly the best text to speech voice service I have used, They have pretty realistic high quality natural voices, they have a lot more like Rod or Karen but I can't seem to find SAPI5 versions of Infovox4.
Link to the voices: also includes Jane, John, Kate and Rodger, I can't seem to get the SAPI5 voices running on Windows 11 (apparently it only works in Windows XP, Vista & 7)

Getting the voices is really simple.
Aaron, Jane, John, Kate, Rodger (make sure you use XP to 7 if you wanna use them), Mary, Vicky and William are simple to install, as they are bundled in installers.
For the other voices, you have to install the Infovox 3 engine in the site I linked, open and click install, then go to "Program Files/Acapela Group/infovox 3 demo/engine" in the folder, you must run "d.bat" as administrator, This would register all the voices you installed, the US English folder is already installed, make sure to drag all the US voices to that folder to use them, the British voices and that one Indian voice are in the site (make sure to get Queen Elizabeth, she is the voice that has the full British folder), this would make all of the voices run.
