Launch Terminal and close window when finished using AppleScript

terminal.scpt

tell application "Terminal"
	activate
	do script "sudo say --rate=140 \"Intergalactic Planetary\" && kill -9 $$"
	delay 5
	repeat
		try
			do shell script "ps a | grep -v grep | grep 'sudo say --rate=140 Intergalactic Planetary'"
			delay 0.5
		on error
			exit repeat
		end try
	end repeat
	close front window
end tell

There is a some weirdness with how the ps command strips out quotes. IIRC, AppleScript like to "think different" when it comes to quotes as well. Use at your own risk 🤷‍♂️
