Signal Processing
PVTK	Extract HTK features as training vectors for libSVM, apply trained SVMs directly to feature files TGZ archive, [svn://mickey.ifp.uiuc.edu/PVTK SVN repository] (Sarah Borys and MH 2005-8)

Nested STFTs	Efficient Simultaneous Multi-Scale Computation of FFTs Description, stft.c (Dave Cohen, Camille Goudeseune, Mark Hasegawa-Johnson 2009)
Improved Mistral	State of the Art Text-Independent Speaker Verification System,especially for NIST SRE Based Mistral Open Source package. Improved and New Features: add full factor analysis(eigenchannel and eigenvoice), instead of simple factor analysis(eigenchannel) add multi-threads for Windows as well as Linux support read HTK format feature/model add an effective Algorithm for fast implementation of FA. code optimization(for FA) fixed some bugs Source: /ws/ifp-32-2/hasegawa/pineking/programs/Improved_Mistral (Qingsong Liu 2009)
Computation

HTK Parallel	Split an HTK command into batch jobs for a cluster (Bowon Lee, 2006) Description, HCopy.pl, HVite.pl, HERest.pl, HResults.pl, [svn://mickey.ifp.uiuc.edu/HTK_parallel/ SVN repository]
Data
dtmfseg	Segment audio files at DTMF tones [svn://mickey.ifp.uiuc.edu/dtmfseg/ SVN repository] (Bowon Lee, 2006)

improved MVA	Perform mean and variance normalization and ARMA filtering It's essentially this version, improved: better error reporting (e.g. failing to open file tells you so instead of core dumping) more accurate mean and variance estimation (doubles instead of floats in strategic places) faster computation in the case of MV (ARMA order 0) source: svn://mickey.ifp.uiuc.edu/corporaNormalizationScripts/fisher/MVA.cc binary: http://mickey.ifp.uiuc.edu/speech/akantor/fisher/programs/bin.Linux/MVA

Phonetic Transcription Tool

This tool computes American English phonetic transcriptions from plaintext. Its HMM either generates a most likely phonetic transcription, or forces alignment if a phonetic transcription is provided.

So, it gives a reasonable pronunciation for both out-of-dictionary words and partially pronounced words.
