Before we change our speech we should work in our attitude and outlook to life. Stutter is more than merely a blocked speech or fluency problem; its a psychodynamic disorder which manifests but not limited to a speech disorder.

dear brother sahran
before we change our speech
we should accept the fact that we are human
we are not complete and that shortage differ from person to person
and by controling ourself when we speaking
إن شاء الله we can speak easily and confidenet without any stutter
or at least speak well as possible as we can
