For individuals with complex physical and communication challenges, auditory scanning provides an accessible way to interact with communication devices and digital tools. This technique, often paired with switch scanning, allows users to select messages or commands by listening to spoken prompts and activating a switch at the appropriate time.
In this post, we’ll explore:
- What auditory scanning is
- Live voice scanning as a supportive strategy
- A simple progression for switch scanning, based on Ian Bean’s research
- Where to find resources to support implementation
What is Auditory Scanning?
Auditory scanning is an access method used in augmentative and alternative communication (AAC) where options are presented auditorily instead of visually. This technique is essential for individuals with visual impairments, motor challenges, or cognitive difficulties that make direct selection difficult.
In an auditory scan, a list of words, phrases, or categories is read aloud in sequence. The user listens and activates a switch when they hear the desired option. There are two primary types:
- Single-switch auditory scanning (user waits for the right moment to activate)
- Two-switch step scanning (one switch moves through options, the second makes a selection)

Live Voice Scanning: A Natural Approach
Live voice scanning is a human-assisted version of auditory scanning, where a communication partner reads choices aloud instead of using a synthesized voice from an AAC device. This method is particularly helpful for beginners, providing a natural rhythm, flexible pacing, and increased engagement.
Live voice scanning can be beneficial when:
- The user is just learning auditory scanning.
- The person needs support in attention or comprehension.
- A more natural and engaging interaction is preferred over synthesized speech.
Key strategies for live voice scanning:
- Use clear and consistent wording. Keep choices simple and structured.
- Pause between options. Allow processing time.
- Observe for nonverbal cues. Some users may indicate a choice with eye gaze, movement, or facial expression rather than a switch.

Switch Scanning Progression: Steps to Success
Ian Bean’s Switch Progression Road Map provides a structured learning path for individuals using switches to control AAC and digital tools. This step-by-step approach ensures users develop both motor and cognitive skills needed for effective switch use.
Switch Scanning Stages
- Cause and Effect Learning
- The user learns that pressing a switch creates a response.
- Example: Activating a toy, turning music on/off.
- Single-Switch Timing
- The individual learns to wait and press when an item is highlighted.
- Example: A switch-activated game with visual or auditory prompts.
- Two-Switch Step Scanning
- One switch moves through options, the other selects.
- Example: Navigating an AAC menu.
- Formal Scanning with a Grid
- The user makes choices within a structured AAC system or software.
- Example: Selecting words in a communication app.

Final Thoughts
Auditory scanning and switch access are powerful tools for communication and learning. By combining structured switch training with personalized live voice scanning, users can develop independent communication skills at their own pace.
For professionals and families working with AAC users:
- Start simple and gradually build skills.
- Use engaging activities that motivate the learner.
- Incorporate live voice scanning as a bridge to electronic scanning.
