Why do people who have accents while speaking, seem to lose them while singing?

Question

Specifically, when singing in English, their speaking voice is accented, and their singing voice isn’t… As an example, I came across an Irish Youtuber named CallMeKevin, and he recently posted a cover of NIN’s “Hurt”. His voice is lovely, and he often sings snippets of songs while streaming, but as soon as he starts singing, his accent seems to drop off. I’ve noticed this for other artists, too. Can anyone tell me why this happens? Or is it just my perception?

Different part of the brain controls singing than speaking. Most stutterers can sing, Mel Tillis for example.
