The consonant changes while non-obvious to native english speakers at least are somewhat consistent. Using a different latin character for a sound isn't that big of a deal when learning a language. Once you get to Japanese/Chinese/Korean its normally the least of your concerns. :)

Compare and contrast to English pronunciation of things like: moose goose lose loose hose etc/usw... Quite a disparity between the lot of words despite their similarity.

Sorry for the thread derailment, i'll go sit in the corner and think about my life.
