Having a large brain is also expensive to build. It's always a questions of trade-offs.

You don't need sound. Sign language exists even in humans.
That wouldn't even require large appendages. The "talking" could be done by photophores, or 1cm long flexible vermiform appendages, or controlling the pattern of fur movement.
