I have attempted PyTTS (expostulated) and PyTTSx (the most suggested) and the two Google solutions (gTTS and another by some person named Hung Truong) yet none of them worked under Python 3.4. It appears they haven't been ported to 3.x.
I looked also on StackOverflow and Google, yet all the proposed TTS solutions don't work under Python 3. I'm on Windows 7.
