Because speech impediment cluttering is fundamentally all about language planning, cluttering is not only about speech – in its most narrow definition – alone. This shows for example in the following symptoms. When people who clutter concentrate well on their speech, their speech improves immediately; this is the other way around for stuttering speakers. Also, on difficult topics of conversation, cluttering speakers often have trouble to get out of their words easily; for people who stutter the difficulty of the subject does not matter. Furthermore, speech of cluttering speakers often improves when speaking in a foreign language. This gets worse in stuttering speakers. In addition, reading aloud an unknown text is beneficial for people who clutter; while it isn’t for people who stutter. This is the other way around when reading a known text aloud.
Cluttering symptoms also show in the physical appearance (body language) of cluttering speakers; they come across a lot more restless than stuttering speakers. Former scientist and speech-language therapist Deso Weiss put together an overview based on dozens of years of clinical experience, which he used in differential diagnoses.
