I have installed a number of voice/language packs direct from Microsoft and they are all responding to the preview button in Win10. The problem is that for all my effort, I have only gained once voice (Hazel from English-UK) in VOX ATC. I have rebooted to make sure everything is installed corerectly but I still only have the original MS-David and MS-Zira as well as Hazel.
Do the additional voices from MS not meet the SAPI-TTS requirements?
is there some other step I am missing?
Thanks in advance!
