Does AAC impede natural speech?—and other fears Even when a child's communication impairments are interfering with his or her cognitive, social and emotional development, some parents and practitioners are reluctant to introduce AAC. This is very understandable since AAC-based communication is frequently viewed as the solution of last resort, condemning a child to a lifetime of abnormal and limited communication. It is considered the end of all hope of natural speech, to be used only after years of failed speech therapy. (Berry, 1987; Mirenda & Schuler, 1988). The fact is that AAC does not represent this gloomy future. Many adult users become extremely proficient with their AAC, and are able to communicate anything they want to, in any circumstance they find themselves.
On the other hand, while it may be appropriate to continue to focus on speech, it is unfair to leave a child with little or no means of communicating effectively while undergoing years of speech therapy. A child who is unable to communicate effectively is unable to participate meaningfully in many activities, and is at great risk for delays in cognitive, social and emotional development. (See When does a child need AAC?) Thus, it is crucial that he or she be provided with at least some ability to communicate that offers some immediate control over people and the environment, and can be expanded or modified as necessary to meet the needs of the future. The following table shows the most common fears and myths regarding the use of AAC, as well as research that refutes such concerns, and practical solutions that directly address these issues.

Multimodal communication Multimodal communication is the use of more than one type of communication methods by one person. Multimodal communication is natural; everyone uses a variety of communication methods all the time. People typically simultaneously use gestures, facial expressions and body postures in addition to speech. This makes communication more efficient and effective as more information is being conveyed than could occur through words alone. Speaking with someone on the telephone or in writing, for example, is not as rich or communicative an experience because we no longer have access to the other non-speech modes of communication being used (Murphy, Markova, Collins, & Moodie, 1996; Van Tatenhove, 1987) A related issue is the use of different mixes of communication modes and styles depending on the people and circumstances involved in an interaction. Generally speaking, everyone uses the method of communication that is easiest and most efficient, but it has to be socially appropriate to the situation. For example, we naturally communicate a certain way when we are with family members or close friends, as opposed to more formal situations. When offered a cup of coffee at home we might get away with a mere nod of the head, a simple grunt or a slight push forward of the cup—-all nonspeech methods of communicating. Yet, nothing less than a formal "Yes, thank you" may feel comfortable at someone else’s house. A child who uses AAC needs this same flexibility all the more because, for this child, communication requires more time and effort. For example, communicating through eye gaze techniques may be sufficient to indicate which type of cereal he or she wants for breakfast at home. However, the child must also be able to switch the mode of communication to meet the needs of partners who do not understand eye gaze communication. For example, sign language may be required in the classroom, and an electronic voice output communication aid (VOCA) in the community. Multimodal communication can ease the vocabulary requirements on any single communication method. If a child is able to get someone’s attention by vocalizing, for example, then there is no need to program an attention-getter onto the child’s VOCA. In addition, children for whom it is not clear which is the best type of communication mode may benefit from being simultaneously taught more than one until a preferred method emerges. Likewise, children whose abilities are degenerating due to a progressive disease may also be taught to use more than one mode of communication in preparation for the future. For example, a child whose motor skills are deteriorating may rely on sign language now, but also be taught communication board techniques (Beukelman & Mirenda, 1992). Ideally, at least some aspects of a child’s AAC program should include simple, unaided methods of communication, as long as they get the job done. (Unaided AAC are communication methods that do not utilize an external device. See Aided vs. unaided systems.) For certain functions simple gestures, eye gaze, vocalizing or body movements are easier, faster and just as reliable. For example, to get someone’s attention, respond yes or no, or refer to something that is in close proximity, these techniques are often preferable because they require less effort. Unfortunately, children are sometimes forced to use their more complicated formal AAC systems even when a simple approach is sufficiently intelligible and substantially faster and easier. Although the intent behind the demand that a child use the more sophisticated system is for teaching purposes, it is unfair and unnatural to expect anyone to choose a more complicated method of communication over an easier and more efficient one. Moreover, it can diminish the value and desirability of using the sophisticated AAC. To summarize, children require AAC systems that accommodate a variety of modes because multimodal communication accomplishes the following.
