Abstract
An adaptive and adaptable multi-purpose math-to-speech translation system is proposed in the paper. Along with the detailed presentation and design approach for the core math-to-speech translation system, exemplary output and tests are discussed. A scripting extension, providing flexibility of the system and enabling the user to adjust the output translations to his/hers preferences is incorporated into the presented solution. Some unit-tests and adaptable versions of translation rule sets are elaborated and evaluated by means of standard measures of machine translation quality. Designed as a flexible self contained solution, the presented system may be applied for various purposes such as e-learning audio presentation systems, educational tools for non-native speakers or visually impaired people, and may be easily adjusted to different national languages.

1.1 MotivationA proper and effective Human-Computer Interaction (HCI) model is an essential and challenging issue in the design of modern computer based systems, especially those intended for e-learning [21, 23], mobile devices [45] or support for people with special needs [26, 33, 35, 42], including elderly ones [34]
The nature of the mathematical notation obstructs semantic reception of the equations and often becomes a significant barrier for visually impaired people, who need the assistance of peer readers or an automated speech system
It verbalizes mathematical expressions defined in various formats: web math notation (MathML), LATEX and EQED to linear textual form of natural spoken language in Polish
Summary
A proper and effective Human-Computer Interaction (HCI) model is an essential and challenging issue in the design of modern computer based systems, especially those intended for e-learning [21, 23], mobile devices [45] or support for people with special needs [26, 33, 35, 42], including elderly ones [34] The research in this area takes into account many different users’ needs, and main conclusions point out the need to increase flexibility and adaptivity of user experience [6]. Most of the present alternative input methods for mathematics do not provide versatile help in editing complex equations
