We've heard from a few folks this morning saying that Google Now apparent has gone quiet, refusing to verbally answer any of the usual questions. We're seeing it, too. Asking "What's the weather like today?" produces results, but you don't get that sultry voice. Probably just a server-side thing (OK, obvious a server-side thing), and we'd expect it to be fixed. But, no, it's not just you that Google Now is giving the silent treatment to.
