Can I recommend to actually begin talking on an exhale. Focusing on “taking a breath” is not a longterm solution for most bc it adds unnecessary things to remember, and moreso, bc unless you are very capable of taking a deep inhale to your diaphragm, it’s most likely going to be a shallow chest inhale (further compounding the problem). Also, your lungs automatically regulate air pressure while taking, so as long as you are breathing normally, extra breaths will also compound the problem. Like many new techniques, this might work briefly (as you feared). But now you know how to address it if/when that does happen
