Speak text voice changing randomly

My 14 Pro changes its speak-text voice(on Shortcuts) from Siri Voice to another voice randomly.

This is so uncool because it automatically speaks text when battery falls below 20%. And now I have to hear this weird uncool robotic and funny voices other than Siri 3.☹️.

Been updating software ever since and one of the things highlighted in the software updates is, “Bug Fixes”. But hey , here I am update after update.

Apple please work a little harder on this one, thanks.
