What’s the Difference Between ChattyInfty2 and ChattyInfty3?
Math expressions or scientific documents ranging from secondary education to higher education levels can be written or edited by using the keyboard with speech output. Files made with ChattyInfty can be saved in various accessible formats: LaTeX, MathML, PDF, HTML or Microsoft Word XML. An original format: IML (Infty Markup Language) is essentially XML and is completely compatible with other Infty software: the math OCR software, “InftyReader” and the Math-document editor for sighted people, “InftyEditor.” All of math expressions are displayed in the ordinary print style. ChattyInfty reads aloud not only texts but also those math expressions. Print-disabled students can access, edit or author math/scientific documents including math expressions with speech output. They, therefore, can share the same educational materials with their sighted classmates. Their teachers can easily prepare those materials by making effective use of InftyReader and InftyEditor. Furthermore, the teachers can directly read documents that visually disabled students draw up even if they are not familiar with Braille.
ChattyInfty3, in addition to providing the functionality of About ChattyInfty2, adopts Multimedia DAISY and accessible EPUB3 is as output formats. In the accordance with this improvement, the application was thoroughly updated. Thus, it is now useful for people with either low vision OR dyslexia. Just as in previous versions, ChattyInfty3 enables users who are blind to read and author mathematical documents with speech output. In addition, low-vision users can improve contrast or magnify the displayed content for ease reading. Visual tracking and synchronized speech allow users with dyslexia to maintain focus on a document. The results delivered by InftyReader can be imported directly into ChattyInfty. Also, ChattyInfty3 is very useful as an authoring tool for producing accessible e-books.
