SFS 4/Windows is a computing environment for PCs for conducting research into the nature of speech. It comprises software tools, file and data formats, subroutine libraries, graphics, standards and special programming languages. It performs standard operations such as acquisition, replay, display and labelling, spectrographic and formant analysis and fundamental frequency estimation. It comes with a large body of ready made tools for signal processing, synthesis and recognition, as well as support for your own software development.

Latest News

January 2004
SFS Version 4.5/Windows released.  Major improvements including new pitch estimation, formant tracking, and pitch epoch location algorithms.  New means for scripting SFS using BASH, SML and MATLAB, with new manual chapter  full of example code.  Improved printing of spectrograms.  Improved usability for many programs. Download here or view release notes.
September 2003 SFS MATLAB API released. The API allows MATLAB programmers to read and write SFS data sets, also to list the contents of SFS files. A utility program allows MATLAB functions to be executed from the command line on SFS files. More details & download.
July 2003 SFS Version 4.4/Windows released. Improved cross-section display. New harmonic analysis/synthesis program. Bug fixes to ESWin. Voicing degree analysis. Improved filterbank synthesis.
