My son is 2 and recently found to be deaf. One usage case I imagined (while we are going through the process of learning sign-language and learning about the forthcoming Cochlea Implant he will receive) is exactly this, so it's gratifying to see some development in that sphere. Sign-language is different to English in the same way German is different to English.. you can translate, but it's not quite the same. Regardless, I did wonder - given how cretinous most Human / Computer Interfaces still are - if learning signing would be a better way of interacting with a machine. It would certainly have the side-benefit that users could talk to deaf people more easily (and possibly would help reduce the stigma that being deaf seems to still have, even today).
