Sound engineers, help me name this vocal sound

Savannah Locke’s “Oh Holy Night” has a vocal quality that I’ve heard many times before in other songs and I was always curious what it was called, as well as the general EQ settings to reproduce it.

I name this song because I feel like it’s a very over the top example that I first heard over the holidays on a random playlist. I can only describe the vocals as “paper-like”. The style is folksy but it’s that particular sound of the vocals I’m interested in identifying.

Also, if there’s a particular nomenclature to these different types of styles or a glossary of some kind I’d appreciate it.

Full disclosure: I’ve sat behind a mixing board as an enthusiast but am no means educated beyond lows, mediums, highs.

Many thanks in advance!
