Consider this for a start:
http://en.wikipedia.org/wiki/Origin_of_Language
I think the research about this would be very interesting--trying to actually prove the Babel account (language origins) through secular research.
Of course the Bible can not be proven merely using science, it can support it as it is able. Also, the Bible does not have to prove itself in every instance; however, the Bible explains how it is to be interpreted: verse upon verse, a little here, a little there. Then this is only done as God allows. During history and time, God has purposely kept people from knowing certain things until he decided to awaken them.
Faith with proper understanding is not something misled (regarding the tower of babel); however, this "proper understanding," if you will, is dependent upon mysteries unvailed to them that sleep. Sleeping here means they were did not know or understand. They awaken when God opens up the their minds as the Holy Spirit speaks from the Bible
So we start here perhaps:
Ge 11:1 And the whole earth was of one language, and of one speech. {language: Heb. lip.} {speech: Heb. words}
Ge 11:6 And the LORD said, Behold, the people is one, and they have all one language; and this they begin to do: and now nothing will be restrained from them, which they have imagined to do.
Ge 11:7 Go to, let us go down, and there confound their language, that they may not understand one another's speech.
Ge 11:9 Therefore is the name of it called Babel; because the LORD did there confound the language of all the earth: and from thence did the LORD scatter them abroad upon the face of all the earth. {Babel: that is, Confusion}
