Subject: Software Package: Lextools

Lextools is a package of tools for creating weighted
finite-state transducers (WFST) from high-level linguistic
descriptions. These descriptions include: strings, regular
expressions, and lists of these; context-free and
context-dependent rewrite rules; and various more
specialized tools (e.g. a specialized tool for building
grammars of the mapping between digit strings and the
number-names for those strings). A version of lextools was
used, for instance, to build text analyzers for the Bell
Labs multilingual tts system

Lextools binaries are available free for non-commercial use
Supported platforms are: linux (i686), sgi (mips2) and sun4.

Lextools is built on top of, and requires, the AT&T WFST
toolkit (version 3.6), available free for non-commercial use
