They’re one of the options for smart quotes and I think they’d be really good for certain types of digital communication, but I don’t want to use them for all of my quotes and I have no idea what they’re called so I can tell my dictation software to input them.

These are the Right and Left Corner Bracket characters. Unicode U+300C and U+300D, respectively. They are part of the box drawing set in the Unicode table, so you might need to select a symbol style font in order to find them in character map. I found them in Segoe UI Symbol.

As to how they are ever used as quotation symbols though, I have no idea! 8)
