Conclusion

Some Augmentative and Alternative Communication devices are Assistive Technology tools.  They range from simple static-display voice-output devices to tablet technology with its many software applications.  These technologies are necessary for use by children with disabilities to improve their language development, and communication opportunities.  iPad software applications provide consistent auditory output, giving the child a chance to learn even without a communication partner.  A child begins the scanning process with a PECS, moves up to a static-display voice-output device or a dynamic-display voice output device, or can use tablet technology with which to learn to communicate.
