Thought experiment: If a group of kids were isolated in an empty room (only have their needs tended to), will they develop their own language?

If a group of kids were isolated since birth till death (but have their needs tended to without any verbal communication), would the kids develop their own language to communicate with one another?

If so, how long do you think it will take for them to develop their own language?
What would they sound like? Will they ever develop verbal communication/language to effectively communicate among themselves?
