Phonology

According to the American Speech Language Hearing Association (asha.org), a phonological disorder involves patterns of sound errors. For example, a child may omit final consonants in words (final consonant deletion), or produce sounds in the front of the mouth instead of the back of the mouth (fronting), to name a few. Some of these patterns of sound errors are developmental in nature, and a phonological disorder occurs when a pattern of sound errors continues past a certain age.
