What Are Speech and Language?
Speech and language are tools that humans use to communicate
or share thoughts, ideas, and emotions. Language is the set of rules,
shared by the individuals who are communicating, that allows them to
exchange those thoughts, ideas, or emotions. Speech is talking, one
way that a language can be expressed. Language may also be expressed
through writing, signing, or even gestures in the case of people who
have neurological disorders and may depend upon eye blinks or mouth
movements to communicate.
While there are many languages in the world, each includes its own set
of rules for phonology (phonemes or speech sounds or, in the case of
signed language, handshapes), morphology (word formation), syntax (sentence
formation), semantics (word and sentence meaning), prosody (intonation
and rhythm of speech), and pragmatics (effective use of language).

How Do Speech and Language Normally Develop?
The most intensive period of speech and language development for humans
is during the first three years of life, a period when the brain is
developing and maturing. These skills appear to develop best in a world
that is rich with sounds, sights, and consistent exposure to the speech
and language of others.
There is increasing evidence suggesting that there are "critical
periods" for speech and language development in infants and young
children. This means that the developing brain is best able to absorb
a language, any language, during this period. The ability to learn a
language will be more difficult, and perhaps less efficient or effective,
if these critical periods are allowed to pass without early exposure
to a language. The beginning signs of communication occur during the
first few days of life when an infant learns that a cry will bring food,
comfort, and companionship. The newborn also begins to recognize important
sounds in his or her environment. The sound of a parent or voice can
be one important sound. As they grow, infants begin to sort out the
speech sounds (phonemes) or building blocks that compose the words of
their language. Research has shown that by six months of age, most children
recognize the basic sounds of their native language.
As the speech mechanism (jaw, lips, and tongue) and voice mature,
an infant is able to make controlled sound. This begins in the first
few months of life with "cooing," a quiet, pleasant, repetitive
vocalization. By six months of age, an infant usually babbles or produces
repetitive syllables such as "ba, ba, ba" or "da, da,
da." Babbling soon turns into a type of nonsense speech (jargon)
that often has the tone and cadence of human speech but does not contain
real words. By the end of their first year, most children have mastered
the ability to say a few simple words. Children are most likely unaware
of the meaning of their first words, but soon learn the power of those
words as others respond to them.
By eighteen months of age, most children can say eight to ten words.
By age two, most are putting words together in crude sentences such
as "more milk." During this period, children rapidly learn
that words symbolize or represent objects, actions, and thoughts. At
this age they also engage in representational or pretend play. At ages
three, four, and five, a child's vocabulary rapidly increases, and he
or she begins to master the rules of language.

What Are Speech and Language Developmental Milestones?
Children vary in their development of speech and language. There is,
however, a natural progression or "timetable" for mastery
of these skills for each language. The milestones are identifiable skills
that can serve as a guide to normal development. Typically, simple skills
need to be reached before the more complex skills can be learned. There
is a general age and time when most children pass through these periods.
These milestones help doctors and other health professionals determine
when a child may need extra help to learn to speak or to use language.

How Do I Know If My Child Is Reaching the Milestones?
The following links will send you to a list that can determine if
your child's speech and language skills are developing on schedule.
Choose the appropriate age bracket for your child. You should talk to
your child's doctor about anything that you answer "no" to.

What Should I Do If My Child's Speech or Language Appears to Be Delayed?
You should talk to your family doctor if you have any concerns about
your child's speech or language development. The above checklist should
help you talk about your concerns. Your doctor may decide to refer you
to a speech-language pathologist, a health professional trained to evaluate
and treat people who have speech, language, voice or swallowing disorders
(including hearing impairment) that affect their ability to communicate.
The speech-language pathologist will talk to you about your child's
communication and general development. He or she will also evaluate
your child with special speech and language tests. A hearing test is
often included in the evaluation because a hearing problem can affect
speech and language development.
Depending upon the test results, the speech-language pathologist may
suggest activities for home to stimulate speech and language development.
These activities may include reading to your child regularly; speaking
in short sentences using simple words so that your child can successfully
imitate you; or repeating what your child says, using correct grammar
or pronunciation. For example, if your child says, "Ball baybo"
you can respond with, "Yes, the ball is under the table."
This allows you to demonstrate more accurate speech and language without
actually "correcting" your child which can eventually make
speaking unpleasant for him or her.
The speech-language pathologist may also recommend group or individual
therapy or suggest further evaluation by other health professionals
such as an audiologist, a health care professional who is trained to
identify and measure hearing loss, or a developmental psychologist.

What Research Is Being Conducted on Developmental Speech and Language
Problems?
Scientists are examining a variety of issues related to speech and
language development. Brain imaging studies are defining the relationship
between exposure to speech and language, brain development, and communication
skills. Genetic studies are investigating the likelihood that at least
some speech and language problems may be inherited or passed down from
parents to their children.

Additional studies are characterizing inherited communication disorders.
The effect of frequent ear infections on the development of speech and
language is also an area of investigation. Other scientists are distinguishing
types of speech and language errors to determine which ones may be overcome
by maturation alone and which will need some type of intervention or
therapy.
Another area of study is the effect of speech and language development
on later school performance. Further research is characterizing dialects
that belong to certain ethnic or regional groups. This knowledge will
help professionals distinguish a language difference or dialect (which
should be preserved to help an individual identify with a group) from
a language disorder, which may require treatment.
