singing and fire alarms

I heart singing sm i do it like all of the timeeee but i cant record + upload my singing bc my fire alarm is dead and ALSO my recording quality is ass andddddd i live with my family so I can't yell for songs that very much need to be yelled....... HOW DOES ONE SHINE IN THESE CONDITIONS... 

also i swear im not ass ive done that trick where you put your hands on the front of your ears to hear how you ACTUALLY sound so im not making excuses... this is torture
