Also known as tachyphemia, cluttering is a speech disorder characterized by rapid or irrhythmic speech that is difficult for listeners to comprehend.

Example: The speech of a grade-school boy is hard to understand because some of the sounds he produces are oddly rushed or accented, though otherwise correct.
