INTERNATIONAL JOURNAL OF SCIENTIFIC & TECHNOLOGY RESEARCH VOLUME 9, ISSUE 03, MARCH 2020 ISSN 2277-8616 1655 IJSTR©2020 www.ijstr.org Advanced Machine Learning Techniques To Assist Dyslexic Children For Easy Readability Geeta Atkar, Dr.Priyadarshini J. Abstract : “Dyslexia” is disorder normally occurred in children. In which they are unable to learn the things easily as like normal children. Such kids are considered as Dyslexic Children. Main objective of this paper is to assist such child for easy readability the paper focuses on reading disability of Hindi words. Children of age five to seven years are considered as target, which are having problem in reading. Here some of the software based techniques and some hardware based techniques are discussed. Total 600 sounds of Hindi two letters and three letters words are taken as an input. These audios are trained by using Dynamic Time wrapping algorithm. Their results are compared. After training whenever this system will be used as assistive system for dyslexic children. They should be easily read and recognize the word.

Children who are having dyslexia are normally facing difficulties in Reading, Speaking, Writing, recognizing alphabets and also other difficulties. Dyslexia is not disease. It’s a disorder with which person is born. Most of the time it runs in families. Main difficulty in dyslexia is difficulty in recognising phoneme. Most common issue with these children are they are having trouble in blending several sounds to make a word. These children cannot recognize common words as well. There are normally some issues children are facing. ADHD (Attention Deficit Hyperactivity Disorder) -Children with this disorder are facing problem in reading and other activities. In Executive functioning issue affects the functions like organization, thinking and working memory. Slow processing issue affects reading performance of kid .In this, children are facing difficulties in basic reading skills and getting meaning of it. APD (Auditory Processing Disorder)-It affects the child’s ability to sort through sounds he hears. Child faces the trouble in recognising difference between letters sounds. In visual Processing issue, children are complaining about blurry vision. They often reverse the letters while writing and facing difficulties to stay within lines. Dysgraphia is one of the issues which normally affect ability to spell, ability to form letters and numbers. Dyscalculia makes difficulties in mathematics. In Executive functioning issues which normally affects different areas of learning executive functions contains organizations, thinking and working memory. Slow processing speed is also one of the type which mostly affects reading performance of child. Children are facing difficulties in basic reading skills and getting meaning of it. The paper is focusing on reading disorder which occurs in dyslexic child. Children having dyslexia are in trouble to decode the words. Reading is nothing but ability to match sound with letters and then use that skill to read accurately and fluently. The paper focussing on dyslexic children having age between five to seven years. 2 PREVIOUS TECHNIQUES There are number of techniques are designed for helping dyslexic children. Some of them are software based, some are hardware based. Both are discussed below 2.1 Software based techniques: A. Assistive technology of reading inventions for children with reading impairment with one year follow- up [29] Method: 35 children of aged between 10 to 12 years are participants. Here five minutes reading test is taken. Here data received from examination was analysed by content analysis. Also children are examined by sentence chain test, last non word, word reading test and which picture is correct test. For all these tests some application are used like prizmo program which capture text and reads loudly. Also TTS, Easy writer, Voice reader are used in this method. Two games are also developed like word puzzle; guess the word from few letters. Drawback: Here to many applications are used which leads training less structured and sequential. Also traditional pedagogical instrument is used for examining reading test. Questionaries’ are not equipped as per described phenomenon Solution: Reading concept is extended as gaming information not decoding words. B. Using Gamification to motivate students with dyslexia [30] Method: Class dojo is a platform in which teachers checks behaviour of child. Two main components are there first is awarding badges. Badges are either positive or negative depending on concentration, coping, handwriting, reading, independent work, self-confidence. Second one is reporting system which keeps records of awarded badges Advantages: Here number of opportunities is there using gamification. Second one suggest exploratory approaches Drawback: Its again traditional and time consuming method to assign badges C. A multimedia English learning system using HMM to improve Phonetic awareness [31] ____________________________________ • Ms.Geeta Atkar, Vellore Institute of Technology, Chennai, India, PH: +91-9822342320.
