Statistical Speech Technology Group Software

Our policy: everything we write is free on the web. This wiki is intended to be definitive, because anybody in the group can edit it to add their own software. A spider-indexable backup is at http://www.isle.uiuc.edu/software .

Our software is available via subversion, using login name "anon" with no password (hit "enter" when a password is requested).

On Windows, download TortoiseSVN
On Linux, use the svn command, e.g., svn co svn://mickey.ifp.uiuc.edu/speechfileformats

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 gives the American English phonetic transcription of any string. It uses an HMM model to either generate a most likely phonetic transcription, or if a phonetic transcription is provided, it can perform forced alignment. So, it gives a reasonable pronounciation for out-of-dictionary words, or partially pronounced words.
