# # Speech PROcessing tools - README # # $Author: ggravier $ # $Date: 2003/07/24 15:14:07 $ # $Revision: 1.3 $ # INTRODUCTION The Speech Signal Processing (SPro) toolkit provides the standard speech signal analysis routines. The basic functions needed to build signal processing algorithms are defined in a library and runtime tools are provided for the standard analysis procedure (LPC, filter-bank and cepstral analysis). LICENSE SPro is distributed "as is" under the GNU Public License. See COPYING for details on the license. CONTENT Library (libspro.a): - system.h: system dependent stuff - spro.h: all the definitions for libspro.a - sig.c: waveform I/O functions - header.c: feature stream header functions - spf.c: feature I/O functions - misc.c: miscellaneous stuff that didn't fit anywhere else - lpc.c: LPC based speech analysis functions - fft.c: FFT based speech analysis functions - convert.c: delta, delta-delta, CMS and other convertions Runtimes: - scopy: copy/list of an SPro data file into various formats (HTK, ascii, Sirocco, ...) - sfbank: filter bank analysis - sfbcep: filter bank cepstral coefficients - slpc: LPC analysis - slpcep: LPC-based cepstral coefficients Documentation: - sprodoc.tex INSTALLATION See INSTALL for details. SUPPORTED PLATFORMS As far as I know, SPro has been successfully build and used on Linux, SPARC/SunOS, and HP-UX. It should also work on AIX though this has not been tested so far. This code has *never* been ported to any windows-based OS but if someone ever do that, please let me know (there should be some problems). BUG REPORT To report a bug or any comment or (even better) any contribution, please send a mail to [email protected]. HISTORY See CHANGES for details. AUTHOR Guillaume Gravier - [email protected] CONTRIBUTORS In alphabetical order: Raphael Blouet, Pierre Duhamel, Johnny Mariethoz, Sylvain Meigner, Alexey Ozerov, Jacques Prado.
