S-voice is an Android specific app which relies heavily on Android and Google services to work, so I'd say no. That would be the last app I'd expect to see on a Samsung WP8 phone.

I would expect Samsung to make some other cool OEM-specific apps for WP8 though, since they are heavily into the whole "differentiation" thing on the Android side. No crappy skins like TouchWiz because thankfully Microsoft protects us from system slowing garbage like that, but probably some other cool apps.
