The core vocabulary approach treats inconsistent phonological errors by focusing on high-frequency and high-value.
Children with inconsistent phonological errors (inconsistent phonological disorder). Inconsistent phonological disorder is characterized by better imitation than children with childhood apraxia of speech, oromotor skills that are within normal limit, no groping, no prolongations, or repetitions of speech sounds, appropriate prosody and diadochokinetic rate.
Choose a pool of 70 target words with help from parents/caregivers, the child, and their teachers. Focus on 10 targets every session with the main point being consistency of their best production rather than perfect productions. This approach requires parent participation. High frequency words that are meaningful to the child and family can be used as targets as well.
