Applescript voice control
Seems like this sorted it:

tell application "System Preferences"
    reveal pane id "com.apple.preference.universalaccess"
    delay 1

    tell application "System Events"
        tell window 1 of application process "System Preferences"
            select row 12 of table 1 of scroll area 1
            delay 0.1
            click checkbox "Enable Voice Control" of group 1
        end tell
    end tell
    quit
end tell
