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?
