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

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

5 Part for the teacher/clinician AFTER REMEDY: assessment Relisten to a particular student’s exercise sessions Automatically assess a particular student’s exercises by means of speech recognition Possibility to investigate the speech recognizer’s analyses in ‘Praat’

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

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

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

10 Story reading exercises Stories are presented sentence by sentence/paragraph by paragraph on the computer screen

11 Word reading exercises Exercise 1: child reads, reading tutor listens –The previous word stays on the screen until the next word is presented –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

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 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 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

15 Story reading exercises Exercise 2: reading tutor reads, child reads –The reading tutor reads to the child (speech synthesis) and the child tries to read along with it –The next sentence/paragraph is presented When it has been detected that the last word of the previous one was read by the speech synthesizer (NO speech recognition)

16 Story reading exercises Exercise 3: reading tutor reads and restarts, child reads –The reading tutor reads to the child (speech synthesis) and the child tries to read along with it When the child appears to be x number of words behind on the speech synthesizer (speech recognition), the reading tutor goes back in the text to restart reading from there on –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)

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 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

19 Story reading exercises Additional options –The next word is presented when the previous one was read (exercise for fast but inaccurate readers) –After the reading of a story, the difficult words are selected an presented again to the child as an exercise choice between: whole word, phoneme-by-phoneme, syllable-by- syllable feedback
