1.1. DJGPP: a C compiler for MS-DOS
The latest version (v2) of this C compiler, DJGPP, can be found at D. J. Delorie’s very informative web site (http://www.delorie.com/djgpp) , including a form-based guide to help you determine what zip files to download. The collection of DJGPP files on the CD-ROM was a combination of djdev203.zip (1.5 Megabytes, unzips to 4MB), gcc2952b.zip (1.9 MB) and bnu2951b.zip (2.5 MB, unzips to 5.5 MB). (As future modifications to the software are made, higher numbers may be used in these file names instead of 203, 2952 and 2951, in future. In any case, downloading djdev*.zip, gcc*b.zip, and bnu*b.zip, where * indicates some numbers should be OK.) The documentation files in faq211b.zip are also recommended. README.1ST is a short guide to installation. My even shorter guide is as follows:
This is a reliable Edinburgh-standard version of Prolog developed at
Psychology Department at the University of Amsterdam, and downloadable
SWI-Prolog home page provides a good deal of information about its many
virtues. For use under Windows, shift-click on the “Win32 binary” link.
downloadable code for version 3.4.4 was about 1MB long. When the file
w32pl344 has downloaded, clicking on its icon will guide you
through a self-installation process which will create various
in C:\Program Files\pl and set up file properties so that clicking on
files with the suffix “.pl” (for “Prolog”) will execute them using the
2. Sound file editors and analysis software
2.1. Cool Edit
Cool Edit is a sound file editor originally produced by Syntrillium,
also has some functions for analysing and manipulating signals. The
version of Cool Edit 2000 is one of a suite of different versions. Adobe Systems Incorporated acquired the technology
of Syntrillium Software in May 2003. On August 18th, 2003 Adobe
rebranded version of Cool Edit Pro 2.1 as Adobe Audition™ software.
See Adobe's Cool Edit site, www.cooledit.com,
for further details.
WaveSurfer is an open source tool for sound visualization and
manipulation. WaveSurfer is being developed at the Centre for Speech Technology (CTT)
at KTH in Stockholm, Sweden, one of the world's leading centres of
research. As well as KTH's excellent software, WaveSurfer also contains
of the excellent speech analysis tools that were previously sold by
(ESPS/waves+) before it was acquired by Microsoft, including a pitch
algorithm based on the ESPS tool get_f0, and a formant tracking
based on the ESPS tool formant, which are among the best pitch-
formant-tracking tools available.
is another excellent and versatile package of tools for speech analysis.
3. Finite-state toolkits
3.1. PC-KIMMO: A Two-Level Processor for Morphological Analysis.
Information and downloads are available from SIL.
3.2. Xerox Research Centre Europe's finite-state toolkits and demonstrations.
Labs - Research finite-state machine library: it remains to be seen
long these will be available.

4.1. The comp.speech Frequently Asked Questions
site provides a range of information on speech technology,
synthesis, speech recognition, speech coding, and related material.
are 250 comp.speech WWW pages and they include over 500 hyperlinks to
technology web sites, ftp servers, mailing lists, and newsgroups.
4.2. The Hidden Markov Model Toolkit HTK is a portable toolkit for building and manipulating hidden Markov models. HTK is primarily used for speech recognition research, and is in use at hundreds of sites worldwide. The HTK release contains extensive documentation and examples. HTK was originally developed at Cambridge University Engineering Department, but was later sold and developed by Entropic until 1999 when Microsoft bought Entropic. Microsoft has now licensed HTK back to Cambridge University, which still redistributes HTK. In short, while Microsoft retains the copyright to the existing HTK code, you can get access to it from the Cambridge HTK website.
