OpenGrm Libraries

OpenGrm is a collection of open-source libraries for constructing, combining, applying and searching formal grammars and related representations including:

  • NGram Library: makes and modifies n-gram language models encoded as weighted finite-state transducers (FSTs),

  • Thrax Grammar Compiler: compiles grammars expressed as regular expressions and context-dependent rewrite rules into weighted finite-state transducers.

  • SFst Library: operations to normalize, sample, combine, and approximate stochastic finite-state transducers.

  • Work in progress, under construction Baum-Welch library Work in progress, under construction: performs Baum-Welch and Viterbi training on weighted transducers.

These libraries use the OpenFst library for their underlying finite-state models.
