Welcome to the TreeQ Package. V1.4.1, Summer 2004 Jonathan Foote jtfoote@ieee.org 0) RTFM Before you do anything, read the documentation in tqman.pdf 1) INSTALLATION Installation should be simple: first make the tqlib library file in the tqlib/ directory, then make the tools in the src/ and proc/ dirs. The makefiles default to putting the binaries in bin/, which you can then add to your path. If you want 'em someplace else, it's easy to change the makefile. Once everything is built, test the code with the tutorial script in test/ (you might want to follow along in the tutorial chapter of the documentation). 2) GETTING STARTED WITH SPEECH AND SIGNAL PROCESSING The proc/ dir contains signal processing tools that you should use if you don't have HTK. I've used free code from OGI to do front-end processing like cepstral analysis. Look at proc/00readme for how to get the code and how to link it with the proc/ tools. 3/2002: the OGI tools seem to be defunct (there's a new version which is not compatible with my code). I don't feel comfortable giving away my copy of their old code. However HTK is now free and available from http://htk.eng.cam.ac.uk/ The only HTK tool you need is HCopy to paramterize your audio files. Make sure you use the following config options: TARGETLABEL=HTK SAVECOMPRESSED=F SAVEWITHCRC=F On cygwin/Windows machines, use the following HConfig options to get the byte swapping right: NATURALREADORDER=T NATURALWRITEORDER=T If your are new to speech work I would recommend the following book as a good intro (it will explain things like cepstral coefficients): Rabiner, L. R. and B. H. Juang (1993). _Fundamentals of Speech Recognition_. There's a lot of good training data for speech applications. Look at the at the comp.speech FAQs at ftp://rtfm.mit.edu/pub/usenet-by-hierarchy/comp/speech/ 3) ADMINISTRIVIA This code is released under a BSD-like license. You are free to use and modify the code, however I retain the copyright and request credit for all applications of the TreeQ code base. Please send bug reports and comments, wise and otherwise, to jtfoote@ieee.org. I will try, but can't guarantee, to look at them. Bug reports with fixes, of course, are most welcome and will be rapidly included. Good luck, have fun, and share + enjoy. Jonathan Foote, Summer 2004.
