Introduction
Reading with dyslexia could be considered as accomplishing two jobs at the same time: decoding the words and understanding the message of the text. Before a challenging word becomes understandable, the sentence itself could have gone unnoticed. One person with dyslexia gets stuck decoding the words he or she does not know; another decodes perfectly but too slowly; the third understands an entire chapter while reading it aloud but cannot comprehend it when the same text is written.And that is why people talk about different kinds of dyslexia. Dyslexia is a convenient term, but there are no separate types of dyslexia, no four boxes. Types of dyslexia illustrate the patterns of difficulty reading rather than separate diagnoses.Text-to-speech does not diagnose, teach, or replace support from professionals, but it can help to find alternative ways of accessing the information provided in written form. Listening to spoken audio, synchronizing highlighting, controlling the pace of reading, and replaying the content will allow a dyslexic reader to pay less attention to every single word and concentrate on the meaning of the text.If it sounds helpful, you can try Readify text-to-speechon a document or a book of your choice.

What is dyslexia?
Dyslexia is a learning difference, primarily associated with word decoding and spelling. It might influence accuracy, fluency or both. Dyslexia is neither low intelligence, nor laziness or lack of ideas.According to the definition of the International Dyslexia Association, dyslexia is a specific learning disability related to difficulties in word decoding and/or spelling. A similar view on dyslexia as one of the kinds of reading disorders is shared by the NICHD overview of reading disorders.The important question for practical purposes is not only "which type of dyslexia is it? ", but also "where exactly does the reading break down? ". This answer will help to choose instruction, accommodation, and tools for reading with dyslexia.
Are there really different types of dyslexia?
Terminology such as phonological dyslexia and surface dyslexia helps to discuss the reading profiles of dyslexics, but it is not four separate diagnoses that are identified in online checklists. Dyslexia assessment involves a detailed analysis of history, language background, decoding, spelling, fluency, phonological processing, rapid naming and comprehension. Types of dyslexia in this guide are a map of reading problems, not a diagnosis.

Four typical reading problems in case of dyslexia
1. Phonological dyslexia: problems with decoding of unfamiliar words
Phonological decoding is the ability to associate written graphemes with the corresponding sounds in a word. If decoding is difficult, the reader recognizes a known word but finds it hard to pronounce an unknown one.Imagine a student who understands a science topic in a discussion but keeps getting stuck on words such as photosynthesis and chlorophyll. Decoding every word makes comprehending the explanation impossible. Names and academic terms could also serve as a blockage.Text-to-speech will pronounce these words in the context of the text. It does not teach the patterns of spelling but will help to avoid getting stuck on one particular word and missing the whole idea. Listening to the word and seeing it at the same time will help the reader to perceive its phonetic and graphical structure.TTS gives instant spoken model of the word, reduces the load of decoding, keeps the flow of the sentence, allows to replay any word or passage.To use the feature on a long PDF or ebook, use Readify text-to-speechreader.
2. Surface dyslexia: slow recognition of familiar words
The term surface dyslexia is used for the difficulty with fast recognition of words, especially the words that are pronounced according to irregular spelling patterns. English is full of these words: said, one, enough, though, and yacht.The reader with such a pattern of reading will sound out every word. Reading will be accurate but slow, making the rhythm and meaning of the sentence hard to track.Listening to audio and synchronization with the highlighting will help the reader to follow which sentence is read now, recognize the visual form of the word and keep on track of the page.There is no need to race. Calm and slow reading is usually more effective than a dramatic narration.
3. Rapid naming difficulties: slow reading
Some dyslexics can decode words but take much more time to pronounce names, letters, numbers or words. This problem is typically described as rapid automatized naming and in everyday terms means slow reading, broken rhythm, frequent pauses and fatigue on long passages.Using text-to-speech will create an external rhythm. The reader will be able to listen to the audio, follow the highlighting and pause only when necessary to think about the information, not the mechanics of reading.The most helpful reading speed is the one at which a reader is able to explain the listened information: it could be slower for a textbook and faster for a well-known article.
4. Double deficit pattern: decoding and rapid naming difficulties combined
Double deficit hypothesis describes readers with difficulties in both phonological processing and rapid naming. In everyday terms, it means that the unfamiliar words are hard to decode and familiar information is not retrieved fast enough.In this case, text-to-speech can help with multiple obstacles: listening to the audio will help to decode words, highlighting to follow the flow, speed controls to adapt to the material and replay to revisit the confusing part.None of these options replace the reading instruction but they can make school, workplace and personal reading easier during the instruction.
How text-to-speech can help with reading with dyslexia
Not everyone benefits from TTS in the same way. According to a meta-analysis of text-to-speech and read-aloud tools, there was a small but positive effect on comprehension of students with reading disabilities. Later research on children with reading and language difficulties also showed that TTS could help, though more research was needed on features such as highlighting.This careful finding corresponds to the actual practice. Text-to-speech is a tool, not a universal solution. It works best when its options are adjusted for the reader and the task.With reading aloud, the reader will be able to grasp the meaning of the text without having to decode each word first. It is useful when reading to understand science, history, or workplace information rather than to test word-decoding abilities. Highlighting will help you see where exactly the voice is, connect spoken and written language, and get back to it after pausing.

With text-to-speech, the reader can replay the sentence, adjust the speed and listen to the audio while taking notes. This kind of audio reading for dyslexics could make a long assignment, report, or book more manageable.
How to use text-to-speech for dyslexia reading support
The simplest way to use the technology is to start with one actual reading task, not with trying out all the options.

1. Adding the actual text you need to read
Add a homework chapter, an article, a PDF file, an email, or instructions. Start using TTS in the Readify web appor try out dyslexia-friendly text-to-speech.
2. Choosing clarity over personality
Choose the voice with a natural rhythm and no exaggerations. Test a paragraph before committing to the whole text.
3. Keeping the text visible
Wherever possible, follow the highlighted text instead of listening to TTS as background audio. Seeing and hearing at the same time will help the reader to stay on track. If the screen seems to be overwhelming, read smaller chunks of text.
4. Adjusting the reading pace
Start with the pace of speaking. After a paragraph, try to summarize the main idea. If you can do it, the pace is fine. Lower the speed or raise it only when the comprehension is still clear.
5. Replaying and taking notes selectively
Replay the exact sentence that causes difficulties and take notes about the idea in your own words. This way, the passive listening turns into active reading.

Tips for parents, students, and adult readers
Parents can start with short sessions and let the child choose the voice and the speed of reading. Students can listen once to catch the main idea, follow the text for the second time, and replay only what is necessary for taking notes. Adults can start with postponed emails, policies, reports, forms, and training manuals. Usedyslexia reading support with Readify when decoding prevents access to the content.
Conclusion
