Speech and language services concentrate on communication areas including language, articulation, voice, and/or fluency for students birth to age 21. This service can also aid in broadening areas of academic and functional needs.
Speech/Language Pathologists’ main responsibilities are working in the areas of articulation (speech production), voice (which involves pitch, quality and volume), and fluency (which is sound/syllable repetitions, blocking and use of conversation “fillers”). Speech/Language Pathologists also work in the area of language, which is described in more detail below. They are responsible for diagnostic testing in all of the above areas.
