Stuttering is a speech impediment that is caused when the regular speech pattern is
interrupted by repeated syllable or letter sounds. This happens when a person cannot say
the word all at once. The person may also experience tremors and eye blinking while
stuttering.
Stuttering can happen while they’re talking to a bunch of people or to one person. In the
UK, stuttering is referred to as stammering or disfluent speech.
There are about three million Americans that have been diagnosed with stuttering. It can
affect anyone, but the group that it affects the most is children between the ages of 2 to 6
years old. This is the time that they are learning to talk and make sentences. In this age
group, boys outnumber the girls in stuttering. With adults, the stuttering rate hovers
around 1 percent.
