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.
