[Star Wars] Can C3PO speak Shyriiwook?

I was thinking about Chewbacca and C3PO just and I thought it would sound hilarious if C3PO spoke Shyriiwook in his voice.

So is that one of 6 million forms of communication he can speak?

Yes.  He understands it, he has a voice synthesizer and isn't limited by biology, so logically he can speak it.

He doesn't use it with Chewie, though, because Chewie understands Basic just as well, and C3PO prefers to use Basic if his conversation partner understands it (e.g. conversing with R2D2).
