- On Linux, use the svn command, e.g., svn co svn://mickey.ifp.uiuc.edu/speechfileformats
Learning
- Pronounce
- An orthographic string to phonetic string mapping tool. (Arthur Kantor, 2007)
- 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.

- Improved Mistral (Qingsong Liu 2009)
- State of the Art Text-Independent Speaker Verification System,especially for NIST SRE
- Based on 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

- Manually and automatically segment CT and MR image stacks
- Description
- SVN repository
- improved MVA (Arthur Kantor 2008)
- Perform mean and variance normalization and ARMA filtering
- It's essentially this version but with
- 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)
- binary SVN repository
Miscellaneous
Other scripts written in perl, python, bash, and ruby can be found in SVN archive.
There is also auto-generated documentation for them.
