Liblouis – braille translator, back-translator and formatter

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.

Features include:

  • 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.
