kmouth in Italian or another tts utility (I hope not to have already post it, in that case... sorry!)

Could you tell me the name of a text to speech program different from
kmouth wifh allows me to type, press enter, get the text uttered,
retype....  for ubuntu 10.04?
or (but I prerfer the first one)
could you tell me the exact instructions to configure kmouth in Italian?
Note that if in kttsd I click on Add a new voice and then on Ok when I
come back there are no voices, I think it's a program bug and so I
prefer the first choiche.
That's all! Thanks a lot!!!
