Cued Speech is a visual mode of communication in which mouth movements of speech combine with "cues" to make the sounds (phonemes) of traditional spoken languages look different. Cueing allows users who are deaf, hard of hearing, or who have language/communication disorders, to access the basic, fundamental properties of spoken languages through the use of vision. Using Cued Speech in addition to American Sign Language (ASL) or other communication philosophies, such as Sign Supported Speech or Simultaneous Communication, can be beneficial in a multitude of ways. Chicago's Alexander Graham Bell Montessori School offer a full-inclusion program providing a Montessori curriculum with both individualized and small-group instruction that allows students unlimited opportunities for interaction with same-age peers who are deaf, hard of hearing, and hearing. Cued Speech is used throughout the school with all the students, and ASL is used as a supplement. Each teacher receives formal instruction in Cued Speech and uses cues with the students. The Illinois School for the Deaf (ISD) incorporates Cued Speech into its bilingual program, with Cued Speech used, but with wide variance, in classrooms and subject areas throughout ISD's pre-kindergarten through post-high school instruction.
