That weird voice thingy

First post on this thingemo, just thought I might add my input to it.

Theres a program on every windows computer called Microsoft SAM, its basically a voice modelling program, and it reads out text that's inputted into it. It can pronounce any normal properly spelled english word, except when newer words such as l33t$p3@K words, where they have to be spelt phonetically, but maybe we'll get to the point in having a language that is spelt easily enough to understand as a second language learner at first look. If a computer can't do it, then how in the world is a human supposed to do it?!
