"Noam is a JavaScript library for working with automata and formal grammars for regular and context-free languages". Also has pretty cool examples using viz.js <https://github.com/mdaines/viz.js/>_

Nice set of utilities for OpenFst includes implementation of Categorial semirings.openfst-utils.

Toolkit for manipulating word lattice built on top of OpenFst. Includes support for reading and writing HTK compatible lattices.

Provides Hadoop training of Kneser-ney language models, written in Java.

Barista is an open-source framework for concurrent speech processing.

Neural network phone duration model on top of the Kaldi speech recognition framework, (Interspeech paper) <https://phon.ioc.ee/dokuwiki/lib/exe/fetch.php?media=peopleicassp2014-durmodel.pdf>_

Juicer is a Weighted Finite State Transducer (WFST) based decoder for Automatic Speech Recognition (ASR).

SailAlign is an open-source software toolkit for robust long speech-text alignment implementing an adaptive, iterative speech recognition and text alignment scheme that allows for the processing of very long (and possibly noisy) audio and is robust to transcription errors. It is mainly written as a perl library but its functionality also depends…

Bob is a free signal-processing and machine learning toolbox originally developed by the Biometrics group at Idiap Research Institute, in Switzerland.

CMUdict (the Carnegie Mellon Pronouncing Dictionary) is a free pronouncing dictionary of English.
