GRM Library

The GRM Library is a general software collection for constructing and modifying weighted automata and transducers representing weighted grammars or statistical language models.

The GRM Library was developed by Cyril Allauzen, Brian Roark and Mehryar Mohri when the authors were working at AT&T Labs - Research. It uses the FSM library for representing weighted transducers and automata. Hence, the models created by the GRM library can be used with the OpenFst library by first converting them into the FSM textual representation.

The GRM Library is available for download for non-commercial use (only as binaries).
