Have you actually heard someone say "teng cars" instead of "ten cars", Kooyeen? "Cam be" strikes me as weird, too. Where did you get this from?
Hey Amy,
well... I don't know!

You know, I have problems with n's because of my dialect, so it's very difficult to pay attention to natives' speech. It sounds like a minor difference to me, and it's a pain in the back to listen to every minor feature instead of listening to understand the meaning. Also, I listen to too much music, and singers don't pronounce words carefully.
I found several sites that said that kind of assimilation is very common, but they all seemed to be British websites.
Actually, I think I hear something similar from African Americans. Their "man" sometimes sounds like "mang" to me, but I think that N is actually nasalized, as I've heard.
CalifJimThe mastery of these patterns -- if mastery is even needed -- is not to focus on the individual combinations that are theoretically possible, but to imitate a native speaker in a more mindless way.
Hi Jim,
yeah, I think that's what I do, but then I realize I might be doing weird things with my mouth, and so I feel the need to ask someone. I don't think I have big problems in sound production, if I try carefully and consciously. I notice the difference between un-believable and um-believable, when I try to say them, but when I try to "hear" that difference... heh, if it's in fast speech, I might assume it could be either way. The problem seems to become a major problem when I don't think too much about the way I'm pronouncing words, and I end up asking myself... "Is this something I picked up somewhere or is it just me?" - LOL, you know, I think I might "unconsciously" have some features of Canadian rising.
Well, I've been trying to pronounce the N's correctly, and it seems to me I sound better. I really got them all wrong. I realized I said "since" as "sing-s". Now I finally say "prince" basically the same as "prints"!

And thank you all!
