Are there ready-made and fast enough implementations of word comparison in VBA?

Question

Visual Basic

The essence of the problem:
There are huge texts of several thousand words, it is necessary to find tautologies and somehow highlight them. Comparing identical words partially solves the problem, but in addition, you need to find words with the same root. Moreover, everything is implemented on an extremely slow VBA, so the comparison should be fast.
I also heard that you can attach programs written in Visual studio to the office, perhaps there is something ready in one of the languages ​​\u200b\u200bsupported by it.
