There are four types of errors in articulation. These are best remembered with
Substitution, Omission, Distortion, and Addition.
1. SUBSTITUTION - occurs
when one sound is substituted for another.
Examples: I azzume Villiam's buthday it Thuzday.
2. OMISSION - occurs when
a sound is left out that is too hard to pronounce.
Examples: Please print tree copies of the repote.
3. DISTORTION - occurs
when the sound is not left out or substituted but does not sound right. There
is an attempt to make the sound but it is misarticulated.
Examples: "kerrec" vs. "correct" / "tell me" vs "till me"
4. ADDITION - occurs when
an extra sound is added.
Examples: Illinois, Des Moines, Merlot and Salmon.
