Speech Recognition Helps Visually Impaired People Writing Mathematical Formulas

We present a web-based application that can use a speech dialog to write mathematical formulas. It is suitable also for visually impaired people. A voice control is simple and easy-to-use to reach accessibility goals. All functions are separated to relevant categories in menu and accessible via mouse as well as voice. Application is based on X+V [1] technology, java web-server and browser-side scripting.

1. Introduction
Mathematical expressions are basic components in the domains of math, physics, computer science and engineering. People can write them on a computer in many ways utilizing various applications. For example very popular mathematical editor TeX [2] or WYSIWYG editors are used. In this contribution we present a web-based application, which can be used as an accessible formula editor for visually impaired people as well as a simple application interface for the rest. The main principle is to use a speech dialog to enter mathematical formulas. A voice control is simple and easy-to-use to reach accessibility goals.

1.2 Goal
The goal is to make a formula writer, which is suitable for healthy as well as disabled people. An application should be as much intuitive as possible in order to minimize confusion and maximize efficiency (especially working speed). It will be good to apply existing software technologies to increase compatibility and reliability.
