Hello Buddy.
You had to read and not ask for a tray!
In total you have at least 2 topics devoted TTS voice - see them.
I do the following:
1. Remove the directory content and save folder - everything is there.
2. 3 voice files from the archive to get copy without unpacking the voice folder in the directory content.
3. run iGO. The window shows you the language selection - choose your and beyond.
4. After configuration's enter its options - voice and you should see your TTS.
select and use - have a nice day
