In the Speech Hierarchy Approach, the SLP works on one sound at a time and progresses to working on the sound in isolation, syllables, words, phrases, sentences, and conversation.
Isolation: Given 20 sounds and a verbal prompt or model, STUDENT will articulate the sound(s) of / / at the isolation level with 80% accuracy in 4 out of 5 opportunities.
Syllable: Given 20 words or pictures and a verbal prompt or model, STUDENT will articulate the sound(s) of / / at the syllable level with 80% accuracy in 4 out of 5 opportunities.
Words: Given 20 words or pictures and a verbal prompt or model, STUDENT will articulate the sound(s) of / / in all positions of words at the word level with 80% accuracy in 4 out of 5 opportunities.
Phrases: Given 20 words or pictures and a verbal prompt or model, STUDENT will articulate the sound(s) of / / in all positions of words at the phrase level with 80% accuracy in 4 out of 5 opportunities.
Sentences: Given 20 words or pictures and a verbal prompt or model, STUDENT will articulate the sound(s) of / / in all positions of words at the sentence level with 80% accuracy in 4 out of 5 opportunities.
Conversation: Given a reading passage, STUDENT will independently retell the story by articulating the sound(s) of / / in all positions of words at the conversational level with 80% accuracy in 4 out of 5 opportunities. https://www.speechtherapystore.com
Evidence-Based Practice
This practice was first developed by Van Riper in 1978.
"The hallmark of traditional therapy lies in its sequence of activities for: (1) identifying the standard sound, (2) discriminating it from its error through scanning and comparing, (3) varying and correcting the various productions until it is produced correctly, and finally, (4) strengthening and stabilizing it in all contexts and speaking situations." Van Riper, 1978 p. 179.

One study found that the traditional approach (in combination with minimal pairs approach, auditory discrimination, and Cued Articulation) was successful in treating articulation errors in children.
