SPEECH AND LANGUAGE NEWS
March 2008
The
United States Department of Homeland Security has released several videos to
help Americans, including older Americans and individuals with disabilities and
special needs, prepare for emergencies.
The videos are available at:

out the rest of the website, also.
There is a section for children entitled Ready Kids.
During the first years of life a child
acquires the major portion of the phonological system of language. They learn to control their voices and their
vocal mechanisms; to control extremes and variations in pitch and volume; to
control resonance (vowels) and constrictions (consonants) and the timing
aspects of alternating them. Since
motor and speech developments are related, the child must develop the motor
skills not only to produce the individual speech sounds but also to combine
them rapidly. Therefore, the easier
sounds to produce are the first phonemes to appear.
During speech development, phonological
processes occur. These are innate
alterations of normal adult sounds by the child that are used to simplify the
sound system of a language. They are
part of normal development, but often worry both parents and
teachers. Eventually, the child will
eliminate these processes and will acquire the full set of adult sounds. For example, final consonant deletion is
when the child deletes the /t/ in "cat" and says,
"ca". This process is usually
eliminated by 3 1/2 years old. Some of
these processes may persist for several more years. For example, the stopping of the fricative "th" is when
the child substitutes /d/ for "th" and says, "dem" for
"them". This process can
still occur after the age of 5. These
are only two examples of the many processes children progress through on their
way to the adult model of speech.
Please remember that each child is unique and has his/her own rate of
development. It is only when the child
fails to acquire the phoneme or suppress the phonological process within the
normal time framework that a speech problem might exist. At that point, further assessment would be
recommended.
