Speech vs. Language


Speech: the motor action occurring from combined use of the

upper body muscles producing inhalation, exhalation,
phonation and articulation.
We have to learn to modulate our


Vocalization for volume, pitch, resonance and intonation
Articulation for intelligibility
Fluency for clarity and meaning


Language: the use of identified methods that make up a
cultural communication system. This can be hand use, word use
or unaided altogether.
It is often composed of a

Development


Predisposition for language (Vygostky)

…what children learn on their own and without aided guidance isn’t a
true reflection of what they understand.
language deployed by adults can scaffold children’s
development, yielding what he called a “zone of proximal
development”
Speech production is learned early, yet takes up to 7 years to
develop into a refined model.
Refer to the handout on English speech sound development.

Disorders vs.
developmental delay
7


Know the developmental milestones of typical child
development .
Disorders occur outside of this ‘typical’ time period.

Disorders
8




Oral motor disorder
Articulation disorder
Phonological disorder
Language disorder




Word finding problems
Expression-verbal and/or written problems
Literacy: listening, speaking, reading and writing
Pragmatic disorder

Oral motor disorder
9



Cause: muscle weakness or poor transmission of neural
messages to the peripheral system.
Dysarthria: is caused by a decrease in muscle tone. Babies
who demonstrate poor feeding are often ultimately diagnosed
with low oral tone. This leads to speech production delays.
Apraxia: is caused by a disruption of the neural transmission
of movement to the muscles. This causes problems in a
coordination of speech sounds into words.

Early signs of speech apraxia has an impact on a child’s ability to
read and leads to further disruption of reading comprehension.

Articulation disorder
12



Specific problems relating to producing speech sounds
Children develop a rapid coordination of speech sounds into
words. If muscle tone is weak or the messages are interrupted,
speech disorders occur.
Types of Articulation problems:




Substitutions
Omissions
Transpositions
Dialect and regional accents are NOT a disorder

Phonological Process disorder
13

Patterns of sound error productions




Fronting – “tup”/cup, “das”/gas
Backing - “gog”/dog
Consonant Cluster reductions – “boken”/broken
Vowel irregularities

Language disorders
14


A continuum of problems that relate to listening, speaking,
reading and writing.
A child may present with any of the following difficulties:

Word finding problems,

Learning new vocabulary

Following directions or understanding a sequence of thought

Sound-to-letter correspondence

Reading fluency & comprehension

Repeating sequences of numbers, letters or words

Spelling problems

Written expression (including grammar, syntax and semantics)

Communication disorders
15


Inability to transmit information to others, given
linguistic and social norms.
Speech production & language formation may be
within normal limits but if the message isn’t received
correctly, Communication Breaks Down
 Autism
spectrum disorders
 Pragmatic disorders

Voice Disorders
16

Problems associated with the
pitch of voice – puberty issues with boys
 volume – too high can be a pragmatic disorder
 resonance quality –talking inappropriately through the
nose
 harsh, hoarse or raspy due to respiration and/or over
use, cancer

Fluency Disorders
17


Fluency means the flow of speech
Speech becomes dysfluent when
 Something
interrupts the rhythm of the message.
 Repetitions
 Long
pauses
 Hesitations
 Prolongations

Incidence
19

6.1 million children in the U.S. receive special education
services



Of that, 1.1 million of those children receive speech and/or
language services!!
However, this number does not include all of the children who
have speech and/or language problems secondary to other
conditions (deaf or hard of hearing, PDD, autism, cerebral palsy)
WHO estimates that about 15% of the world's population lives
with some form of disability

Reading Experiences of Children with
Developmental Disabilities
22


These children have fewer opportunities for being involved with literacy
experiences;
These children experience significant communication impairments and are further
impaired by intrinsic or individual factors such as






Their specific disability type,
Degree of physical impairment and
Cognitive, perceptual or linguistic abilities
They often have significant language disorders which leads to reading impairments;
Many times educators have trouble understanding that children who don’t use
speech can still learn to read; and
Low expectations of learning potential leads to decreased language and literacy
experiences and/or sophistication.




Spoken language abilities are closely related to literacy
development - however, children diagnosed with mild-tomoderate articulation impairments do not necessarily have
trouble with literacy learning.
Children with speech impairments demonstrate deficits in
phonological awareness, narrative and print related skills.
Phonological awareness skills have been identified as being
the best predictor of reading outcomes.

Importance of intervention
24



phonological processing skills (phonological
awareness, working memory, use of phonological
codes to maintain information in memory)
language processing (comprehension and use of
morphology, syntax, production of narratives and
comprehension of figurative language).
…leads to significant literacy impairments in later
years.

Next steps…
25




Develop a policy for screening speech & language use in KG 1
& 2 and any student who is enrolled up to G6,
Develop policies for intervention and monitoring of student’s
progress
Develop a Tier Approach to Intervention (s)/RTI
Develop a Reading Recovery Program for students no longer
receiving daily reading intervention (generally beyond G5)
