I’ve used the recent version… but after i found out that it DOES NOT support x64 bit, i decided to throw it in the non-64bit supporting software pile and installed it on my old computer running Windows Vista Ultimate x32. It’s definitely better then Vista’s Speech Recognition, but the interface is not pretty, it’s more like the Windows 2000 interface. But the great thing was that you don’t have to Train it for it to work, it works right out of the box. also, this is not a resource demanding software, i’ve also installed it on XP, running within VMware with 512MB of ram and a Intel Core 2 Duo 2.33GHz Processor——(Xp on VMware only used One Core-not Two) and it ran pretty smooth, the only problem i had was a .5-1 sec delay every so often. I’d recommend this if it supports x64, but unfortunately… it doesn’t. I would recommend this to anyone that uses x32 and needs a good Speech Recognition software, it is still the Best out there.
