No, an isolated baby definitely will not learn language.

There has to be exposure. But humans are programmed to learn and use language when exposed to it, which cats and chimps are not. It may be a single gene (FOXP2) or it may be several.

Here's my reference again, which I posted in another reply to you as well:
