This book was written for a group of students with autism who have speech- enough to state requests or recite dialogs but not enough to discuss a topic.Verbal autistic students may have functional speech but it may be difficult for them to extract the right word/language at the right moment required. Expressive language may lie dormant and the student may need a way to bring these thoughts to the surface. Spelling a word may be easier approach for these students than saying a word or thought aloud.Also, many verbal students may experience a "road block" towards intentional-communication beyond the previously learned functional or social speech. If the speech is rote/habit/stim, people may be deceived by their speech and believe that the student cannot think beyond those uttered words.
