How to remove breathing sounds from your audio recordings

When I did corporate education narrations, half of the work was breath and mouth opening/closing control. Reading was the easy part.

Begin recording = inhale, open mouth, wait fraction of second then speak

Mid-sentence inhale = decide where to breathe in text, and at that word, leave mouth open, inhale then continue speaking

End recording = end talking, leave mouth open

(Worse than the breathing sounds was wet mouth smacking open and close sounds when I needed to inhale, or at start or ends of dialogue.) _
