Consonants I can do pretty easily. It's just making a sound with your teeth, lips, and tongue. Vowels you have to hold your mouth perfectly and make some sort of weird animal sound and hold it for the right amount of time and put the right inflection on it. I generally skip vowels when I speak, much to the chagrin of anyone who doesn't know me well and can translate. For example, at work when I ask someone if I can help them find something, it comes out "Cn I hlpu fnd smthng?" Hate vowels, and when I'm emperor of the world they'll be abolished. Finns and Hawaiians will have to just deal.
