ARTICULATION and PHONOLOGY

Home About

"Articulation" is the production of speech sounds. Intelligibility is a measure of how well speech can be understood. Someone with an "articulation disorder" can be hard to understand because they say sounds incorrectly. They might substitute one sound for another (i.e. " I hurt my weg." for "I hurt my leg."?. They might distort the sound so it sounds funny but is still recognizable as the same sound. The other way to produce a sound incorrectly is to omit it entirely.


"Phonology" is the science of speech sounds and sound patterns. Every language has rules about how sounds can be combined. If a child does not use the conventional rules for his/her language but develops their own, they may have a "phonological disorder". In this case, groups of sounds rather than single sounds produced at the back of the mouth-they make them all at the front of the mouth. So instead of saying "cup", they say "tup" or instead of "go" they say "doe".
