Low-Tech AAC Devices  

Low-tech voice-output communication devices use digital technology to record speech, are easy to program, and require a power source.

Who Can Benefit from Using Low-Tech AAC Devices

  • Low-tech devices can introduce a young child or early communicator to the world of augmentative communication. This is sometimes called “exposure.”
  • Use of low-tech AAC devices can provide non-speaking students and unintelligible speakers with opportunities to participate in daily routines and share experiences with peers.
  • Low-tech AAC devices can be used to target specific language development.
  • Intervention using low-tech AAC devices can be an effective strategy for students with challenging behaviors.
  • Some students may use low-tech devices in place of their high-tech systems in select situations/environments.
  • High-tech device users may use a low-tech device when their primary device is out for repair.

Student/User Considerations for Low-Tech AAC Devices

  • Who can benefit from low-tech devices?
  • How will the device be used to improve communication or participation?
  • How will use of the device be tied to the student’s IEP and/or daily activities?
  • What can be done to keep the student interested and motivated?
  • When and where will the device be used?
  • What family/school/other supports are available? ◦Is the device age-appropriate?
  • Have the student’s preferences been considered?

Keys to Successful Device Selection

  • Match the needs/abilities of the student and the characteristics of the environment to the 
    features of the device.
  • Use a team approach in decision-making.
  • Provide trials with equipment whenever possible before purchase.
