So, I listen to several podcasts by people who are the children of Indian immigrants to the US, and I swear there's a very slight accent feature, where the K sound is closer to a G. So, e.g collection is closer to gollection, or company is toward "gompany." Is this a thing? Possibly it's actually a California accent, since most of them are in the Bay Area, but I don't think I've heard it elsewhere.

In general, is there a study of kids-of-immigrants' linguistic features?

There's stuff like this with older Jewish kids of immigrants I've observed in my family, but it's hard to disentangle from older NY/New Jersey accents plus sprinkling Yiddish, and a hard-to-duplicate way of saying "oy." But I don't know that I've noticed specific consonant or vowel shifts like that.

I've wondered about this, even with regional things. I was born and raised in the Midwest, but my parents were both from the northern Rockies region.

I always thought that my grandparents pronounced things funny, so I clearly didn't have the same accent they did, but friends pointed out that my vowels sounded funny compared to everyone else's.
