Transitioning between audio track across cut

I have an audio track of an interview and I want to edit a few words out. When I cut out the words I dont want and the two tracks play one after the other, there is a noticeable crack (dont really know how to describe it without uploading the audio). basically, it doesnt sound smooth and it doesnt sound as if it is one sentence. it sounds like it was cut together. is there a way to blend these together better so it sounds like one continuous sentence?
