For each child in your home, you can maintain a word list. Each child will have a shortcut on their desktop that allows them to practice their words for the week.
All you need to do is add the list of words to the program, and set it as the default test.
You can see a sample of the word entry screen below:
For each word in the test, you can provide a phonetic pronunciation in case the speech engine doesn't say it correctly, as well as provide a sentence for context. The image above shows the preview of using the word in a sentence. The program allows you to copy and paste from other programs to make it very easy to set up the tests.
