Change speak tones and pronunciations in audition?

Hi! first of all, english is my second language so it might be a little difficult to explain what i'm asking.

Is there a way to change the tone of a speaker in audition?

Like if i recorded myself speaking and said something that sounded weird, can i change that tone to sound another way? without having to re-record the audio.

Im wondering because sometimes when i interview people for videos in my workplace they just stop speaking but their last syllable sounds like they are going to continue speaking, Or like change a bad pronunciation of a word, like fixing just a letter of a word. It could help me a lot to fix little errors and mistakes like those. 

Thank you in advance!
