Or should they all just be cleansed?

I am not trying to be a smart ass but how can voice recognition work with stuttering such as ga..ga..ga..ga...go over there or slang that change on a daily basis. As far as accents yes it is supposed to work.CanYouDiglt

I don't know, that's why I was asking. I was only curious if there was any information microsoft released regarding the voice recognition in situations like those.

So not very well then? 

Is the Xboxone capable of keeping track of peoples accents, speech impediments and slang usage?
