That s a common condition known as "word jam". It s from congestion buildup in your throat hence why people clear their throats before making speeches. If your words are getting caught in your throat, force yourself to cough as many times as you can to dislodge as many of them as possible. There s also an information density limit, varying depending on your height and distance to the nearest ley line, but usually too high to reach. However, when delivering long monologues very quickly we approach the limit, and words will get clogged in your throat and mouth until some of the ambient knowledge dissipates. Just go to your dentist and ask them to scrape your mouth clean. They ll get rid of all the excess words that built up, allowing you to talk as much as you want. This is perfectly normal and nothing to worry about.
If you want to try a home remedy, just drink some good old lube! The words will become as slippery as a serial killer at large and exit right out of your talking hole! Even the ICU doctors will be impressed by your ingenuity!
