Choosing a Vocabulary File
Choosing an appropriate vocabulary file is imperative to the success of
the device user. Saltillo suggests that a qualified speech language
pathologist, teaching staff, parents, and device user are all part of the
decision process of choosing an appropriate vocabulary file.
When choosing a file, consider the following:
• The device’s access capabilities
• The user’s current and potential cognitive capabilities
• The potential effect of screen orientation on the user
• The user’s ability to work better with pictures or symbols
• The vocabulary’s ability to be customized
Considering the Device’s Access Capabilities
The device’s access capabilities depend on the number of buttons on a
page.
File Buttons per Page
4 Basic Provides 4 buttons per page
VocabPC Provides 12 buttons per page
MultiChat Provides 15 buttons per page
WordPower Offers 20, 24, 30, 42, 48, 60, 80, and 108 buttons per page
Considering the User’s Cognitive Capabilities
It’s important to consider the user’s current and potential cognitive
capabilities—his or her current literacy level and emerging literacy.
