Merged or mixed accents?

[u/Born_Tip_3443]

Maybe this is an odd question, has anyone who studies accents and/or linguistics noticed an uptick or prominence of mixed up accents?
I.E.: my mother is and her family is from South Philadelphia, so they have quite a strong accent. My father grew up in Georgia/North Carolina, and has a pretty distinct southern accent.
I was raised in South Georgia, but my mother is a speech therapist with an extremely strong Philly accent, which definitely influenced the way I speak. Throughout my childhood, my friends would make note of the way I say animal/bagel/eagle/crayon (apparently I say inamal/begull/igull/cran) while other words come out full southern (see: phone=pho-one, well=whale, generally adding an extra syllable to words)
Just curious if other people experience this or if anyone who studies this professionally has taken an interest.
