The Liblouis software suite provides an open-source braille translator, back-translator and formatter for a large number of languages and braille codes.
It is a set of libraries designed for use in any of a number of applications, both free and commercial.
It is written in C so that it does not require a runtime environment and hence can be used in applications written in high-level languages such as Java and Python.
Liblouis is based on the translation routines in the BRLTTY screenreader
This is free and open source software.
Key Features
- Support for computer and literary braille.
- Contracted and uncontracted translation for many languages.
- Hyphenation support.
- New languages can easily be added through tables that support a rule- or dictionary based approach.
- Tools for testing and debugging tables are also included.
- Supports math braille (Nemeth and Marburg).
- Supports screen-reading programs.
