I guess my accent is not too funny after all! I just installed the English version of Dragon NaturallySpeaking and read a chapter of "Charlie and the chocolate factory" to my computer. It's working quite well so far, except for some peculiarities of the program that I have to get used to. For example, when I wanted to write the word Charlie in the previous sentence it somehow refused to write out the full name and kept writing a c instead (yeah, I'm writing this post without typing

).
All in all I had expected it to be much worse and it's a nice surprise!

And I don't have to worry about my spelling anymore. It's all taken care of.
