Articulation and Phonology:
What are speech sound disorders?
Most
children make some mistakes as they learn to say
new words. A speech sound disorder occurs when
mistakes continue past a certain age. Every sound
has a different range of ages when the child should make the sound
correctly. Speech
sound disorders include problems with articulation
(making sounds) and phonological processes (sound patterns).
What are some signs of an articulation disorder?
An
articulation disorder involves problems making
sounds. Sounds
can be substituted, left off, added or changed. These errors
may make it hard for people to understand you.
Young
children often make speech errors. For instance, many
young children sound like they are making a "w" sound for
an "r" sound (e.g., "wabbit" for "rabbit")
or may leave sounds out of words, such as "nana" for "banana." The
child may have an articulation disorder if these
errors continue past the expected age.
Not all sound
substitutions and omissions are speech errors.
Instead, they may be related to a feature of a dialect
or accent. For
example, speakers of African American Vernacular
English (AAVE) may use a "d" sound for a "th" sound
(e.g., "dis" for "this"). This
is not a speech sound disorder, but rather one
of the phonological features of AAVE.

range during which most children develop each sound, visit Talking
Child's speech chart.
What are some signs of a phonological disorder?
A phonological process
disorder involves patterns of sound errors. For
example, substituting all sounds made in the back
of the mouth like "k" and "g" for
those in the front of the mouth like "t" and "d" (e.g.,
saying "tup" for "cup" or "das" for "gas").
Another
rule of speech is that some words start with two
consonants, such as broken or spoon. When children don't follow
this rule and say only one of the sounds ("boken" for
broken or "poon" for
spoon), it is more difficult for the listener to
understand the child. While
it is common for young children learning speech
to leave one of the sounds out of the word, it
is not expected as a child gets older. If a child
continues to demonstrate such
cluster reduction, he or she may have a phonological process
disorder.
How are speech sound disorders diagnosed?
A speech-language pathologist
(SLP) is the professional that evaluates children or adults with
speech and language difficulties. The
SLP listens to the person and may use a formal articulation test
to record sound errors. An oral structure examination is also
done to determine whether the muscles of the mouth are working
correctly. The SLP may recommend speech treatment if the sound
is not appropriate for the child's age or if it
is not a feature of a dialect or accent. For children, the SLP often
also evaluates their language development to determine overall communication
functioning.

Language Comprehension and
Expression:
Language Comprehension:
Receptive language or language comprehension
refers to one’s ability to process, comprehend,
or integrate spoken language. Generally, it involves
being able to understand what someone says to you. People
with language comprehension difficulties may have
trouble following long directions, remembering
lists of words, and understanding multiple meanings
of words. Difficulties with language comprehension
may also be associated with a language-based learning
disability.
Language Expression:
Expressive language involves putting words together
to form sentences and express one’s self. Areas of expressive language
include syntax or word order, grammar, and vocabulary. Some with
expressive language difficulties may seem to “forget”
names of things around them or seem to “talk around”
a word (e.g., saying, “that thing you eat with” instead
of “fork”). Others
may also have difficulty with grammar or morphology
(changes in verb tense), for example, a one might say
“He running” instead of “He is running.”
Pragmatics:
Pragmatics involves the use of language for social purposes. With
younger children, it involves using language for requesting
objects, actions, information; answering questions, and refusing. For
older children and adults, pragmatics also involves
social reasoning and problem solving skills. People with pragmatic
language difficulties may have difficulty using language in specific
situations such as greetings, informing, promising, and requesting. They
may also have difficulty changing their language for different listeners
(e.g., you talk with your children differently than adults), and with
following conversational rules (e.g., turn taking, staying on topic,
starting and ending conversations, etc.).
Voice:
Voice disorders can be characterized by a hoarse, scratchy, breathy
voice or even the absence of a voice. We’ve all experienced
vocal abuse due to coughing too much from a cold. Common
chronic voice problems can include the following:
Vocal fold nodules and polyps:
These are growths on the vocal folds due
to continuous vocal abuses. For children, vocal abuses can include:
crying, coughing, shouting, and making funny noises. For adults,
vocal abuses include the above listed factors in
addition to gastric reflux and smoking. Physical examination
by an ENT (Ear Nose and Throat Specialist) is required
to diagnose nodules/polyps.
Voice therapy involves teaching good vocal hygiene, reducing/stopping
vocal abusive behaviors, and direct voice treatment to alter
pitch, loudness, or breath support for good voicing. Stress
reduction techniques and relaxation exercises are often taught
as well.
Vocal fold paralysis:
This happens when one or both of the two
vocal cords is paralyzed. Treatment
can involve both medical and behavioral intervention.
Speech therapy focuses on pitch alteration, increasing breath
support and loudness, and finding the correct position
for optimal voicing (such as turning the head to one
side or manipulating the thyroid cartilage).

Fluency:
This involves the fluid forward movement of speech. Breaks
in this fluid movement are disfluencies, or “stuttering” moments
as they are more commonly known. This disorder often begins
in childhood and continues throughout one’s life. Stuttering
involves repetitions of whole words and word parts, blocks or “stops”
in speech, as well as prolongations or “holding on” of speech sounds.
Therapy
for stuttering involves a combination of behavioral and speech
therapy. Individuals and parents learn to modify their environments
and also learn ways to speak in a slower and less physically
intense manner.
