Three ways that speaking the same language could unify people is: 1. Speaking the same language could get everyone to get used to just one without the hassle of memorizing multiple ones.  2. Also, you wouldn't have to worry about discord, arguments, and disagreement because of the lack of misunderstanding.  3. Lastly, speaking the same, exact language could help people to have great experience with a certain language so they can be prepared to be ready for that specific one once they come in contact with it.  Hope that helps you.
