Deleted voice memos from icloud

I was trying to free up space on iCloud and deleted voice memos stupidly assuming they’d remain on my phone - they haven’t and I’m devastated as there were some really special ones on there - my mothers voice and lot of 4.4 gb important lectures . please help me. How I can i get all those deleted voice memos from icloud ?
