To ask what accent your kids have?

Mine code-switch pretty effortlessly between our regional dialect (learnt at school), DP's estuary English, a fairly smooth RP which is how I learnt to speak for professional reasons when I first arrived in the UK, and my more relaxed home language accented English (they do this to take the mickey out of me), depending on who they're speaking with.
Everything changes; vocabulary, syntax, even their voices. Amazing.

I have a very generic/ colourless English accent (I get called ‘posh’ a lot), I’m married to someone who has a beautiful Scots accent (think Ewan McGregor) and our child has the broadest Scottish accent, he sounds like your archetypal wee Scottish Granny, and I absolutely love it ❤️

My dc were all born in the outer Hebrides, now live in Glasgow.

I'm from the East Coast in Scotland and dh is from Northern Ireland.

They are all fairly "posh weegie" sounding, though ds tends to be broader than the girls.

They all also speak Gaelic with a Harris accent as that's where they first learned it.

I think it will depend on how much time they spend with you.
I have a Manchester accent and DH a Welsh one and live near London Both DS’ have no accent at all (I worked when they were little), DD has more of a northern twang as I was at home more with her when she was learning to talk.

My children grew up in a non-English speaking country until they were 6 and 4. They both spoke English with standard southern British accents (as do both DH and I).
We then moved to NW England - DC1 didn’t change their accent, and still sounds “southern”.

DC2 swiftly acquired a strong local accent but only used it at school/with friends, and would switch back to southern at home. As the years went on the school accent became quite a bit less broad, but you can still notice the switch ten years later.

Mine is relatively RP, husband has a neutralish Kent accent....daughter sounds American. No idea (probs YouTube though).

DH just sounds well spoken (he's from Cambridgeshire) and I'm from Yorkshire, but DS has a definite West Country leaning from his mates at school. No Yorkshire whatsoever!

My children all have well spoken southern accent.I have noticed grandchild dropping Ts so have been correcting by repeating word with emphasis on T .

My kids have a mixed accent of the local area and us, that shifts with their moods and who they're talking to.

I grew up being told by teachers that it was great we were an area with 'no accent' (what was called Midwestern American Newcaster accent). I knew it was nonsense then, but it was even more obvious when I moved to England. It's been a couple decades, and I still get people go on at me about my accent. I had it earlier this month at work with a higher up go on about how 'strange' I sound.

My siblings and I all grew up in South London, with parents / grandparents all born in or near Liverpool, but parents had lost their accents mostly (my Mum because she moved south aged 13, my Dad because he was told in his early 20s that he'd never get anywhere unless he lost it) but we all used some northern words at home - we had pumps, not trainers, and tea, and were told not to moider the cat. We all ended up RP (from school) and souf London in code switching in different circumstances to avoid trouble. My sons, born and brought up in London, are also RP but the odd northern word / vowel from home, oddly enough. 10 yr old told my sister to stop moidering him when she ruffled his hair over Christmas!

DD has a local accent (we live SW London), I have quite a strong Geordie accent and DH a softer Mancunian accent. I’m quite glad she’s gone local as I don’t know how that mix might have turned out.

School will be the biggest impact on your child's accent. We live manchester and my children have very heavy manchester accents. I am not from Manchester

My parents were Geordies (my Dad very broad) but I grew up in Brighton so have a neutral southern English accent - I am not sure if that is RP. I understand that I had a Geordie accent until school age (I used to say My Mam) but that was teased out of me pretty fast.

My children have grown up in London and speak with an even more RP accent than I do.

Impossible. Unless you have four robots

There definitely is an IoW accent (it’s technically a West Country accent) but you don’t hear it all that much these days.

@Ladybird69
By this I mean I’m pretty sure your DC would be identifiable as English from their accent. They wouldn’t be mistaken for Americans or Australians etc?

It’s not possible to have no accent?

I'm Irish and DH is Norwegian; DC are bilingual, we live in the North West of England (rural area). DS (8) has a mix. A lot of the time he just sounds a bit well-spoken Northern English, but he slips sometimes into a sort of...speed and sound that I can say he definitely gets from DH. I occasionally hear a twang of Irish. DD (5) is weirdly more Irish sounding when she has those moments.

At the moment, I couldn't say how they'd end up sounding. But we're moving back to Norway very soon, so I'm going to assume they'll end up sounding more Norwegian as they're still only young.

Hmm. My children have London accents I suppose but they spent most of their youth on the Isle of Wight so maybe it's that (is there an IOW accent)? They certainly don't have mine (American). I'm really bad at distinguishing accents unless very obvious (my DD is st Durham and I really like listening to the locals up there). I remember my DD used to pick up American pronunciations when watching those kid's TV shows aimed at tweens.

English in Ireland and they all have very Irish regional accents

I’m in the southwest with a strong accent, ex is from London, however all 4 of my children have no accent at all! Yet we never made a big deal about the way they spoke.

My DS has an English accent - no idea what type as we live in London and he was born here. Parents are from NI & Republic of Ireland. Three different accents in our house - there is a lot of imitating each other!

We live in south Scotland. My dh is Scottish but accent is quite soft, my accent is a mix of north and south England. Ds sounds English with a few Scottish accent words (he went to English nursery until 3), DD sounds English but with a few more Scottish accent words. I'm hoping both will become more Scottish in time.

children tend to pick up local accent. I’m northern but live in the south, and my kids have a southern (south London) accent.

Sibling accents can also vary depending on how old they were when they moved house to a different area or country. An older child is less likely to change accent… though I can’t remember now the average age at which accents tend to become more fixed.
