I have done all tutorials and I use agood quality microphone, I aslo have done some extra practice etc. It can very easily identify what people says but does sometimes important mistakes, the waste of time is correcting it by commanding with speech. In fact it can be my pronunciation even though I speak in the correct order and very eloquently, the problem might also be that I speak fast, not so fast as i speak in greek though, there I make vowels lasting less. I still think that speech recognition needs time to be applicable enough, microsoft should download from users the tutorials and speech tests they have made to enhance it's quality, so the program would be able to understand far more types of voices and accents.
