2. Importance And
Correlation Of
Hearing Mechanism
In The Development
Of Speech And
Language

3. Hearing plays a critical role in communication
skills and learning capacity. Hearing is especially
important in speech and language development.
In order to prevent hearing loss from having a
lasting negative impact on a child’s development,
early intervention is key.
There are four major ways in which
a hearing loss affects children: It causes delay in
the development of receptive and expressive
communication skills (speech and language).

4. Importance Of Hearing
Mechanism In The
Development Of
Speech And
Language

5. To develop spoken language, children must be
able to hear speech clearly and also to
hear themselves. If your child's hearing loss is left
untreated, their basic language development will
often be delayed.
Hearing sounds and words helps children learn to
talk and understand. A child with hearing loss
misses out on these sounds. This can cause
problems with speaking, reading, school success,
and social skills. It is important to have your child
tested if you think he has trouble hearing.

6. Factors Influence Speech
and Language Development
for a Child with Hearing Loss
All children are different in how they develop.
There are developmental stages that most
children follow. Hearing loss can affect how
communication develops in many ways. These
include:
Age at identification of the hearing loss.

7. Consistency of device use.
Type of treatment (early intervention, direct
therapy, school-based therapy).
Cognitive and motor skill level.
Other medical conditions.
Age of amplification.
Family involvement and support.
Type and degree of hearing loss.

8. Causes of Hearing Loss
 Genetic factors.
 Chromosomal differences.
 Anatomical differences.
 Syndromes.
 Prenatal drug or alcohol use.
 Medication used in serious medical situations.
 Prematurity.
 Illness or injury.
 The language deficit causes learning problems that
result in reduced academic achievement.

9. Treatment
 Treatment for a child with hearing loss starts with a
partnership. Children with hearing loss make the most
progress when caregivers and professionals work together.
They also make progress when caregivers work with the
child at home.
 The speech-language pathologist and family will work
together in therapy. The focus of therapy will be to develop
communication skills.
 The speech-language pathologist will likely add listening
games into the session. Listening skills are important for
progress in therapy.

10. Speech and Language Challenges
for Children with Hearing Loss
Children with hearing loss may have difficulty with:
Hearing and understanding sounds around them.
Making speech sounds.
Learning new words.
Putting together sentences.
Using correct grammar.
Effectively expressing themselves.
Understanding speech from other people.

11. Following directions in quiet and noisy places.
Paying attention and controlling behavior.
Following conversations with multiple people.
Making friends and interacting with peers. This
can be caused by difficulty understanding
games, rules, and directions.
Listening and learning in the classroom.
Learning to read.

12. Correlation Of Hearing
Mechanism In The
Development Of Speech And
Language

13. SPEECH & LANGUAGE
Skilled voluntary movement example.
Speech is produced on expiration by movement of
vocal cords. However, generally, it is stated that
language is the means of communicating one’s
thought through spoken words and in writing.

14. Types Of Language
Human beings are capable of expressing their
efficiency and emotions without using speech, like
Work language – conveying message through
quality of work one does.
Body language – conveying message through
physical changes.
Expressive language – conveying message through
emotional feelings.

15. Types Of Speech
Spoken speech – means understanding the spoken
words and expressing ideas in speech.
Written speech – means understanding written
words and expressing the ideas in writing.

17. Spoken Speech – Mechanism
Hear sound – intact auditory pathway from ears to
primary area.
Understand the heard sounds – intact adjacent
auditory into psychic areas.
Express ideas in speech – intact auditory speech
center called Wernicke's area.

18. Writing Speech – Mechanism
See words – intact visual pathway from eyes to
primary visual cx.
Correctly interpret written words – intact
secondary visual areas.
Express ideas in writing – intact visual speech
center (Dejerine’s area).

19. Language And Speech Areas In
The Brain
Four main areas – two receptive (Wernicke’s area
& Angular gyrus) & two executive areas (Broca’s
area & Exner area) – located in association cortex
(i.e. adjacent to cortical areas that are essential in
language formation).
Collectively known as language zone.
As located around Sylvain fissure, also called
perisylvain areas.

20. Receptive Areas / Sensory Speech
Area
Receive and process sensory information for
speech;
Wernicke’s area.
Angular gyrus.
Area 41 & 42.
Receive
information from
Wernicke’s area
processed into
detailed &
coordinated
pattern
projected to
motor cx
initiate
appropriate
movement of lips,
tongue & larynx
produce spoken
speech

21. Executive Area /
Motor Speech
Area
Involve in the execution
of speech expression.
Broca's area.
Exner writing area.

22. Parallel Systems For Speech
There are two parallel systems for speech;
 One is for understanding the spoken words &
producing speech.
Other for understanding written word & producing
writing.

24. Conclusion
As one of our most important senses, the ability to
hear enables us to connect to the world for many
very important, even vital, reasons. Most
importantly, hearing connects us to people
enabling us to communicate in a way that none of
our other senses can achieve.
