Arduino tts issue

Hi Ive been searching for days and have not had luck.
I wanted to do instructable of talking xmas tree. i followed the instructions and downloaded the tts files and i unziped em in the libary folder but they do not show up. thats the first issue.
Anyways i havent found any recent talk about text to speech without any shields. I am.hoping someone can offer advice or a walkthru or link so i can get this arduino talking.
tha ks in advance

I don't know about text to speech, but I have played with the talkie library and it worked pretty well. talkie library
