I am personally okay with this method. Just as long as it is understood that the two portions are saying the same thing. So, if you are doing this, please differentiate between the two portions, such as saying:
English (translated): hello
Spanish (original): hola
Of coarse, this is only my opinion on the matter. It may be decided by those above me that this is not allowed either. If this happens, I will make sure you all know, and will then have to enforce it.
