A speech disorder may include articulation, stuttering, and voice. ASHA's website www.asha.org contains more beneficial information regarding these disorders.
According to ASHA, these disorders are defined as the following:
Articulation:An articulation disorder is the atypical production of speech sounds characterized by substitutions, omissions, additions or distortions that may interfere with intelligibility.
Students with articulation disorders only have trouble with a few sounds (ex. "wabbit" for "rabbit").
Stuttering:
A fluency disorder (stuttering, cluttering) is an interruption in the flow of speaking characterized by atypical rate, rhythm, and repetitions in sounds, syllables, words, and phrases. This may be accompanied by excessive tension, struggle behavior, and secondary mannerisms.
Voice:
A voice disorder is characterized by the abnormal production and/or absences of vocal quality, pitch, loudness, resonance, and/or duration.
