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 MIT 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

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 ggravier@irisa.fr.
