2. 2 Overview Presentation/Demo Overview Reading Tutor: 2 parts Overview of possible exercises with the Reading Tutor Demonstration of the Reading Tutor’s functionalities and exercises

3. 3 1. Overview Reading Tutor Reading tutor consists of 2 parts: –Part for the teacher/clinician –Part for the student

4. 4 Part for the teacher/clinician BEFORE REMEDY: preparation Manage exercises –Make new exercises Manage students –Make new students –Attach exercises to students

6. 6 Part for the teacher/clinician Results assessment: –Classification in 5 groups (cf. CITO): A: best 25%  E: worst 10% –Automatic detection of D- and E-children can be done with high accuracy (as good as a manual assessment) –Only these worst performing children need to be assessed manually  time-saving!

7. 7 Part for the student REMEDY: exercising Make exercises that were assigned to the student (Recordings are made during each exercise)

8. 8 2. Overview Exercises There are 2 types of exercises –Word reading exercises –Story reading exercises

9. 9 Word reading exercises Words are presented one by one on the computer screen

12. 12 Word reading exercises Exercise 2: child reads flashed words, reading tutor listens –Each word is ‘flashed’ on the computer screen so that it is only presented for a very short time (adjustable) –The next word is presented When it has been detected that the previous one was read (speech recognition) When the maximally allowed time to try to read the word has passed

13. 13 Word reading exercises Additional options –Spontaneous help by the reading tutor: After x seconds without a try to read the word (speech recognition), the word is prompted by the reading tutor (speech synthesis) –Ask for help by the student: After clicking a word, the word is prompted by the reading tutor (speech synthesis) choice between: whole word, phoneme-by-phoneme, syllable-by- syllable feedback

14. 14 Story reading exercises Exercise 1: child reads, reading tutor listens –The next sentence/paragraph is presented When it has been detected that the last word of the previous one was read by the child (speech recognition) When the maximally allowed time to try to read the sentence/paragraph has passed

17. 17 Story reading exercises Exercise 4: reading tutor reads and accelerates/slows down, child reads –The reading tutor reads to the child (speech synthesis) and the child tries to read along with it When the child is not able to keep up with the pace of the speech synthesizer (speech recognition), the reading tutor slows down for the next screen When the child was able to keep up with the pace of the speech synthesizer (speech recognition), the reading tutor accelerates for the next screen

18. 18 Story reading exercises Additional options –Cf. word reading exercises Spontaneous help by the reading tutor Ask for help by the child by clicking the word –‘Normal’ reading pace reading tutor is adjustable –Green box that indicates the word that should be read next
