Practice Sessions
By default, the program is in practice mode. In this mode, the user is first shown all of the words in the test.
When the user presses Enter on the keyboard, the agent says the first word, and asks the user to spell the word.
If the word is spelled correctly (including capitalization) the agent congratulates the user, and displays the correct spelling in green.
If the word is spelled incorrectly, the agent informs the user of the correct spelling, speaking the letters one at a time. In addition, the word is displayed in red, followed by the correct word spelling in white.
