Is it compatible with Python 3.5? I can't get the examples running, getting some errors.

Thanks to the authors for making this project !

And I tried to port this project to Python3.5 , i used following steps:

1. 2to3.exe has been used initially to convert Python2 source code to Python3
   Following changes are related to unicode issues.
2. string.letter -> string.ascii_letters
3. c_char(char) -> c_char(ord(char)) , similarly c_wchar
4. str(self) modified in action_base.py and state.py

I have tested moderately with Microsoft Speech engine it works fine for notepad example.
Hope this will be helpful to someone!

( I have created pull request for above changes )
