Articulation and Phonological Disorders
What is an Articulation and Phonological Disorder?
Articulation and Phonological Disorders = A child has difficulty expressing a sound past the intended age of development
Speech sound disorders: an umbrella term referring to any difficulty or combination of difficulties with perception, motor production, or phonological representation of speech sounds and speech segments—including phonotactic rules governing permissible speech sound sequences in a language.
*Result from an underlying motor/neurological, structural, or sensory/perceptual cause.
Organic speech sound disorders include those resulting from:
Motor/neurological disorders (e.g., childhood apraxia of speech and dysarthria),
Structural abnormalities (e.g., cleft lip/palate and other structural deficits or anomalies),
Sensory/perceptual disorders (e.g., hearing impairment).
*Are idiopathic—they have no known cause.
Functional speech sound disorders include those related to the motor production of speech sounds and those related to the linguistic aspects of speech production. Historically, these disorders are referred to as articulation disorders and phonological disorders, respectively.
Articulation disorders: focus on errors (e.g., distortions and substitutions) in production of individual speech sounds.
Phonological disorders: focus on predictable, rule-based errors (e.g., fronting, stopping, and final consonant deletion) that affect more than one sound.
It is often difficult to cleanly differentiate between articulation and phonological disorders; therefore, many researchers and clinicians prefer to use the broader term, "speech sound disorder," when referring to speech errors of unknown cause.
Explaining Speech Sound Disorder to the Family
It can be hard for others to understand what is being said
Key points about speech sound disorders in children
A speech sound disorder means a child has trouble saying certain sounds and words past the expected age.
A child with an articulation disorder has problems making certain sounds the right way.
A child with phonological process disorder regularly makes certain word speech mistakes.
The cause of this problem is often unknown.
A speech-language pathologist can help diagnose and treat a speech sound disorder.
ETIOLOGIES
https://www.speech-language-therapy.com/images/umbrella2015.png
Often, a speech sound disorder has no known cause. But some speech sound errors may be caused by:
Injury to the brain
Thinking or development disability
Problems with hearing or hearing loss, such as past ear infections
Physical problems that affect speech, such cleft palate or cleft lip
Disorders affecting the nerves involved in speech
Some adults have problems that started when they were children.
Others may develop speech problems after:
stroke
other trauma.
Common Adult reasons for SSD:
Which children are at risk for speech sound disorders?
The cause often is not known, but children at risk for a speech sound disorder include those with:
Developmental disorders such as autism
Genetic disorders such as Down syndrome
Hearing loss
Nervous system disorders such as cerebral palsy
Illnesses such as frequent ear infections
Physical problems such as a cleft lip or palate
Too much thumb-sucking or pacifier use
Low education level of the parent
Lack of support for learning in the home
What are the symptoms of speech sound disorders in a child?
Symptoms depend on what type of speech sound disorder the child has. He or she may have trouble forming some word sounds correctly past a certain age. This is called articulation disorder. Your child may drop, add, distort, or swap word sounds. Keep in mind that some sound changes may be part of an accent. They are not speech errors. Signs of this problem can include:
Leaving off sounds from words (example: saying “coo” instead of “school”)
Adding sounds to words (example: saying “puhlay” instead of “play”)
Distorting sounds in words (example: saying “thith” instead of “this”)
Swapping sounds in words (example: saying “wadio” instead of “radio”)
If the child often makes certain word speech mistakes, he or she may have phonological process disorder. The mistakes may be common in young children learning speech skills. But when they last past a certain age, it may be a disorder. Signs of this problem are:
Saying only 1 syllable in a word (example: “bay” instead of “baby”)
Simplifying a word by repeating 2 syllables (example: “baba” instead of “bottle”)
Leaving out a consonant sound (example: “at” or “ba” instead of “bat”)
Changing certain consonant sounds (example: “tat” instead of “cat”)
Case History: What Do We Need? How Do We Get It?
Assessment requires several steps, including:
Identifying that an SSD is present
Analyzing the errors or error patterns
Differential diagnosis
A basic assessment battery includes:
Hearing and speech mechanism assessment
Developmental, educational, medical, and family case history
Receptive, expressive, and literacy language skills assessment
Speech skills (including single words, connected speech, and stimulability) and perception skills assessment

Normative Data & Relevant Statistics
Speech Sound Development Wheel
This wheel shows the average age of when sounds are typically acquired.
Non-standardized Assessment Procedures
Single word testing is used to analyze phonetic context
Connected speech sampling provides information about production of sounds
Importance of connected/naturalistic
speech sample.
There is more opportunity for errors in a connected speech sample vs single words
Sample speech sounds in a variety of word positions
Errors may be produced differently at the word level compared to connected speech
There is more opportunity for analyzing phonological patterns/processes
How to obtain a naturalistic
speech sample?
Interview caregivers and recognize the child’s interests and typical uses of speech
Select toys or objects which peaks the child’s interest
Target different contexts using structured activities
Analyze the child’s speech during interactions with caregivers, peers, and/or siblings
Talking tasks used:
Story telling or retelling
Picture description
Normal conversations
If the child is unintelligible:
Use structure during the assessment
Support the child with as much context as possible
Repeat the child's utterances
(Grigos, 2021)
Stimulability Testing
Is used to examine whether the child can accurately produce a misarticulated sound with modeling from the clinician
Cueing hierarchy can be used to enhance stimulability
Independent Analysis
Place, Manner, & Voicing Analysis
Use to examine characteristics of productive, marginal, and absent phonemes
Model & Replica Charts
Organize each phoneme in the SIWI, SIWW, SFWF, and SFWW position
Examine clusters in each position
Diphthong Sample Words:
Differential Diagnosis
Determining the appropriate classification or label for the speech sound disorder
Speech Delay vs Disorder vs Difference
Speech sound delay occurs when the child i s developing in a normal sequential way but occurring at a slower pace
Speech sound disorder is when mistakes are not "typical" sound errors or the child presents with unusual sounds/error patterns.
Cultural or linguistic diversity may affect communication but should not be considered as a delay or disorder it may simply be a language difference.

Assessment(s) Summary
Example Case Study:
Stephanie was referred by her kindergarten teacher at age six years. She displayed a fifty-percent intelligibility (this presents well below the norm of understandable speech in her age bracket.) Stephanie was making mistakes developing speech sounds “k, g, and f. Her mistakes were errors of substitution, so that she used a “p” for “f,” a “t” for “k,” and a “d” for “g.” These consonants are mastered in conversation by most children before the age of 4 years; Stephanie is also having difficulty with consonants “r” and “th”.
What assessment summary would we include?
Number of sound errors in contrast to sounds produced correctly
Types of submissions/errors
phonological processes
consistency of errors and different testing procedures used
sounds the child has mastered
prompt
intelligibility
Evidence-Based Treatement Approaches
A typical Articulation and Phonology assessment:
Clinician(s) will target a consonant/vowel sound
Sounds become more difficult as assessment(s) continues
Clinician supports/motivates client to correct self responses: This helps aid in improving target sounds and sequences
(ASHA, Articulation and Phonology 2021)
Evidence-Based Treatment Approaches Cont...
Interventions for SSD:
Vertical: repeated and focused practice on an acute number of topics, this targeted practice continues until the student reaches a specified level of skill. This is usually conversational.
Horizontal: practitioner chooses multiple targets and weaves them into the same session. This results in exposing the client to more sounds at one time.
Cyclical: This intervention aims to collaborate with parts of vertical and horizontal approaches where a time limit is provided for practice on a goal or multiple goals. The child graduates to another target or targets for another preset period of time.
Contextual Utilization Approach: This intervention focuses on the notion that speech sounds are formed in syllable based context in connected speech. This is most helpful for children who have an inconsistent relationship with speech sounds and require support to produce sound routinely.
Phonological Contrast Approach: PCA is utilized most often to address phonological patterns of error. This is important for children to develop the necessary sound patterns that help to delineate from one word to another; utilizing opposing word pairs as a target versus a solitary sound.
Four differing contrast approaches:
Minimal Oppositions: an intervention whereby the Practitioner utilizes pairs of words that are different by only one phoneme, indicating a change in meaning.
Maximal Oppositions: choosing pairs of words for the intervention that are the most different due to their contrastive sounds on multiple levels.
Treatment of the Empty Set: this approach is most alike maximal oppositions, choosing pairs of words with the most different sounds that are specifically unknown to the child.
Multiple Oppositions: With the goal of addressing a child’s error sounds, this intervention chooses word pairs which are different than the targeted error with 3-4 selected sounds which reflect: maximal classification and maximal distinction.
Complexity Approach: Using more complex and difficult stimuli, this approach believes that increased complexity helps to promote generalization to other areas, yet to be treated. This approach was inspired by maximal oppositions, but instead, focuses on a hierarchy of complexity with regard to fricatives, clusters and affricates. This intervention does not focus on contrasting sound pairs but instead, on stimulability.
Core Vocabulary Approach: CVA supports children who have difficulty with consistent speech sounds and supports them when other traditional therapies are not working.
Cycles Approach: This approach is designed to meet the needs of children who demonstrate excessive unintelligible speech patterns.
This treatment is structured in a range of 5 to 16 weeks so that one or more phonological patterns can be targeted.
A new pattern is targeted upon the completion of the previous pattern.
Recycling through patterns continues until the targeted areas become present in the child’s regular speech patterns.
Distinctive Features Approach: this approach aims to address phonemes in a child’s speech such as fricative, nasality, voicing and articulation placement. Most often, this is utilized for children who lean toward sound replacement, where one sound is used for another.
Metaphon Therapy: Focusing on metaphonological awareness, which is the observance of the phonological foundation of language.
Consider the notion that children who have these disorders, failed to develop skills for the phonological system.
