Sure. We can't prove that other organisms experience qualia; we can only look at the effects of qualia (e.g. behaviors that are likely to be the product of emotions) and assume that an organism is therefore conscious. The real point, though, is that suggesting language gives rise to consciousness lacks any explanatory power as to why language should be accompanied by consciousness.

Most proponents of the existence of qualia regard them as fundamental to what they call the hard problem of consciousness. People like Chalmers and Searle assume that all of the externally observable behaviors of people could be (at least in principle) explained without the need for qualia; that is, they believe it's possible for p-zombies to exist; this then gives rise to this question of consciousness - if all physical behaviors can be explained without qualia, and yet everyone of us has qualia, how and why does this happen?

I thought the point above was in a similar vein - that qualia and language are theoretically separable phenomena, so that we can imagine a being might have qualia without language, or language without qualia, and so these need to be explained separately. I was trying to point out that we have no proof for the existence of beings that possess these two qualities separately, so that I don't think the theoretical distinction is necessarily true. Just like any volume of gas has a temperature and a pressure, the existence of separate concepts doesn't mean they are physically separable.
