Hi, Yeah if you're using windows 10 it defaults to the Microsoft
OneCore voices on your system. David is the default voice but Zira is
also another of the OneCore voices. There are a few more but you'll
have to browse around. You can also install additional voices for
other languages in windows speech settings. To increase the speech
rate, press control nvda v to access the voice dialog and tab around
to the speech rate setting. Rate boost is also available to increase
the speed even more. You can also press control shfit nvda with any of
the arrow keys to explore the voice settings loop.
