Is it possible to install IVONA (text to speech app) on my Acer Iconia a200? The play store said that it was unavailable for my device. Is there some other way that I can install it. Preferably without rooting. Also, which text to speech apps are best. I think I'm going to go with SVOX Classic TTS if IVONA doesn't work but I'd like to see if there are any others worth trying. Are there any free ones that are worth looking at?
