This happens to all of us at some point. There are mouth clicks that we notice when we play back our recordings. Sometimes they're are none and sometimes we wonder what the heck is wrong with our mouth. Lets start with minimizing them to start with. Generally the clicks start appearing if our mouth is too dry. When you are speaking, you are loosing over a liter of water an hour because the humidity in the lungs is close to 100%. Keep taking sips of water while you're reading. By the time you feel dry it's too late for that moment because it takes time to re hydrate. The next issue is how to minimize the noise on the spot. Every body chemistry is different so you have to experiment with what works for you. Having said that. Apple juice is an amazing moisturizer for the mouth. Mixing some honey with water works for many. Some people I know swear that some molasses in water is a great cure.
If none of this helps then the post production fix that I love is made by iZotope. It is their RX4. It has a DeClick filter that is just magic. Scroll down to Declick and you'll see how specific it is.
