[R] Extracting vocals from a song & pitch detection

Hi so I'm working with a songs dataset and I want to generate a tessitura based on only the vocal part of the song. I'm wondering what techniques or models exist that would allow me to localize the singing part?

Given just the singing audio - I want to leverage a pitch detection algorithm to identify pitch information and how long each note is held in the song in time duration. I want to compare this to a person's voice …
