I've heard (From a native Icelander, on a TV show about savants that had a guy who could essentially memorize and speak a language within a week) that Icelandic is nearly impossible to speak if you don't start as a child... Reading, however, is probably a different story.

I would imagine the phonemes are fairly specific. I've always wondered why teachers didn't get natives to isolate the novel phonemens and present them in connection with phonemes in the native language of the learner, to be honest. Though, apparently my roommates Japanese class effectively did that, via repitition. I can now hear and pronounce several phonemes that aren't present in English, but I will admit they are difficult to aquire as an adult.
...Say what?
sweatdrop Sorry.
Phonemes are the smallest unit of spoken language. For instance, /th/ is a phoneme (technically two, since there's a HARD /th/ and a SOFT /th/). So is /r/ or /s/ or /g/. Linguists have tried to give each phoneme a distinctive written symbol for the purpose of tracking them and identifying them in language. For example, one of the four click sounds in the !Tung language is represented by a !. Another is a #. And so on.
Different languages have different numbers of phonemes. The lowest known is, I think, the Hawaiian native language which had (keep in mind it's been almost eight years since my last linguistics class) 16 or so. The highest ever recorded was somewhere around 45 or so. English is in the mid to high 30s, if I recal correctly; we're low on vowels.
Often the "accent" people have in a foreign language is actually their misinterpretation or inability to pronounce the phonemes of that language. I have a Hel of a time with the rolled /~n/ in Spanish, for instance, which means even when I speak Spanish it doesn't quite sound right.
Phonemes are solidified in children at around six months of age. Before then, babies are capable of distinguishing between all 60+ of them. Afterward, they can only distinguish between the phonemes of their native language or languages.
I theorize adults would be able to regain the ability to hear lost phonemes if they were presented in isolation and the adult tried hard enough.
