---+ !OpenGrm Libraries

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

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

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

   * [[Pynini][Pynini Grammar Compiler]]: compiles Thrax-like grammars from within Python.

   * [[SFstLibrary][SFst Library]]: operations to normalize, sample, combine, and approximate _stochastic_ finite-state transducers.

   * [[BaumWelch][Baum-Welch Library]]: performs Baum-Welch and Viterbi training on weighted transducers.

These libraries use the [[http://www.openfst.org][OpenFst library]] for their underlying finite-state models.
