I use Big Sur 11.4.
I unchecked voices that I don't want in VoiceOver Utility > Speech > Voices.
For example, Daniel for British English and Karen for Australia.
I also made sure the list is the same in system preference > accessibility > spoken contents.
However, they still appear when I press vo+shift+command+arrow to select voice.
I also went to Macintosh HD/system/library/speech/voices, and nothing is there.
I rebooted, reset all setting for VoiceOver in VoiceOver Utility > File > Reset All VoiceOver Preferences.
Nothing helps. All the voices appear in the vo+shift+command+arrow.
How can I uninstall voices?
