Before you get the neutralisation point, adding aicd/alkali doesn't do much, as it is a buffer solution. This also means that [HA]=[A-] leaving Ka=[H+] in the acid equation getting -logKa=-log[H+] which is pka=pH

When you do a titration, there are no changes at all until a sudden colour change, this means that the pH isn't changing that much when your adding alkali/acid, until the neutralisation point. Buffer - Resists changes in pH when small amounts of acid/alkali are added to it.

So it acts as a buffer until the equivalence point (or is it the end point)?
