Siri has a disoriented voice

I'm currently on iOS 14.5 Public Beta 6 with my iPhone XR and that my Siri (whose has a British male voice) seem to sound disoriented at random since when I updated my iPhone to the latest beta available. Has anyone else had similar issues with Siri in which his or her voice has become disoriented or misunderstandable and if so have any of you have any situations for me to fix the issue?
