OpenGrm NGram Library

Red led Version 1.3.17 is now available for download.

NEW NGram is now available on conda-forge. This allows Linux (x86) and Mac OS X users who already have conda to install the library and all dependencies using the following command: conda install -c conda-forge ngram.

The OpenGrm NGram library is used for making and modifying n-gram language models encoded as weighted finite-state transducers (FSTs). It makes use of functionality in the OpenFst library to create, access and manipulate n-gram models. Operations for counting, smoothing, pruning, applying, and evaluating models as well as support for distributed computation are among those provided. It was developed by contributors from OHSU and Google Research. It is an open source project distributed under the Apache license.
