** An inversion appears among [[Film/AttackOfTheClones the clones]]. They all speak with Creator/TemueraMorrison's New Zealand accent even though most of them likely haven't seen Jango Fett in person much, if at all, and the Kaminoans don't speak in said accent.

If the trope goes entirely unexplained, it may have been an attempt to make a character more relatable to the target audience, but could be the result of an actor is NotEvenBotheringWithTheAccent. It's also common for all accents from the same foreign country to be lumped together - if a pair of siblings in an American series are French, then it's likely that their actors will use (real or fake) French accents, but there's little guarantee that their accents will be from the same part of France.

* ''WebVideo/DreamSMP'': The "Sootcraft" family is played by three content creators from different places--Philza's from Newcastle (in Northeastern England), Wilbur lives in Brighton (on the ''south coast'' of England; [[spoiler:although his lore finale alleges his character was born and raised in the U.S, the content creator is of the NotEvenBotheringWithTheAccent variety]]), and Fundy is ''Dutch''. As a result of this, all three of them have distinct accents from each other. There is no in-universe explanation for this.

* Gary Goodspeed from ''WesternAnimation/FinalSpace'' has an American accent while his mother Sheryl has an Australian one.

* ''WebAnimation/Homestar Runner'': In the early days, Strong Bad had a thick Mexican accent, but his brothers Strong Mad and Strong Sad had American accents.

* Star in ''WesternAnimation/StarVsTheForcesOfEvil'' has a general American accent, even though [[AliensOfLondon her parents]] (along with the rest of Mewni) both speak with English accents.

* The [[TheSeventies Seventies]] [=TV=] presenter Johnny Ball was brought up in [[OopNorth Bolton, Lancashire]]. While his daughter, presenter Creator/Zoe Ball was born in Blackpool, Lancashire, she was brought up in [[UsefulNotes/HomeCounties Hounslow, Middlesex]]. Her accent is therefore more that of a middle-class South-Easterner.

** Autistic writer Kel Currie was born in Pennsylvania to Canadian parents, but moved to Nova Scotia at a young age. She now has an accent not typical to America nor Canada. Her non-autistic younger sister has a slight Cape Breton accent like her father.

* ''WesternAnimation/OneHundredAndOneDalmatianStreet'': Dylan is biologically one of Delilah's pups, but while she has a British accent, he speaks with an American accent.

* In ''WesternAnimation/KingOfTheHill'', Hank and Dale both speak in a southern accent variant (though Dale's mostly disappeared as the show went on) but their sons Bobby and Joseph respectively do not. Kahn and Mihn also speak in thick Laotian accents but their daughter Connie has an American accent.

* Often happens when a family immigrates to a country that speaks a different language. The adults will often speak the new language with an accent based on their native language regardless of their level of fluency. While children who are born in the new country or immigrated at an early age, will learn to speak the new language at a native level and without the accents of their parents.

* ''LetsPlay/DreamSMP'': The "Sootcraft" family is played by three content creators from different places--Philza's from Newcastle (in Northeastern England), Wilbur lives in Brighton (on the ''south coast'' of England; [[spoiler:although his lore finale alleges his character was born and raised in the U.S, the content creator is of the NotEvenBotheringWithTheAccent variety]]), and Fundy is ''Dutch''. As a result of this, all three of them have distinct accents from each other. There is no in-universe explanation for this.

* Autistic children have sometimes been known to speak with foreign (or [[WhatTheHellIsThatAccent foreign-ish]]) accents. For example, two autistic YouTubers were born and raised in Australia, but the older sister has a British accent while the younger sister sounds slightly American. Their mother claims it’s because they watched a lot of American and British television shows.

* ''Anime/YuGiOh'': Zigfried has a noticeable accent, [[spoiler:but his younger brother Leon, doesn't.]]

* Children on the autism spectrum have sometimes been known to speak with foreign (or [[WhatTheHellIsThatAccent foreign-ish]]) accents. For example, two autistic YouTubers were born and raised in Australia, but the older sister has a British accent while the younger sister sounds slightly American. Their mother claims it’s because they watched a lot of American and British television shows.

* People who move to locations with a different regional accent than their own tend to pick up on that accent, especially young children. For example, an American family moved to England, but only their daughter Brooklyn picked up a British accent while her parents did not.

* In ''WesternAnimation/ThePrinceOfEgypt'', the Egyptian royal family (except the high priests) have British accents while Moses, who was adopted, speaks in an American accent.
