Introduction

SFS provides a computing environment 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 runs
under Unix, MSDOS and Windows environments and is currently
running on Sun, Hewlett-Packard, Masscomp, Alpha, Linux and
486+PC.  SFS is copyrighted University College London, but is
currently supplied free of charge to research establishments for
non-profit use.  SFS is supplied as is with no warranty or
support.

      Files:     Encapsulated Postscript
                 WordPerfect graphics files
                 GIF files

Utilities:
      Create SFS file, list SFS file, display/print SFS file,
      copy/link/remove items in SFS file, dump contents of SFS
      file.

Analysis programs:
      Acquisition and replay, waveform processing, Laryngographic
      processing, fundamental frequency estimation (from SP or
      from LX), formant frequency estimation, formant synthesis,
      spectrographic analysis, filterbank analysis/synthesis,
      resampling, speed/pitch changing, annotation, spectral
      cross-sections, waveform envelope, filtering, signal
      editing, signal alignment.

File formats:
      Import from many different file formats (WAV, AU, AIFF,
      ILS, HTK, etc); save multiple data items in SFS files and
      compare; standard formats for speech, Lx, Tx, Fx,
      annotations, synthesizer data, spectra, spectrograms, LPC
      coefficients, parameter tracks, etc;  export to binary,
      text, WAV, ILS, HTK, etc; processing history maintained in
      file.

Subroutine libraries:
      Supports SFS file I/O and dynamic memory allocation for
      data sets; device-independent graphics; standard format
      display of data sets, digital signal processing library.

Special purpose languages:
      SML Speech Measurement Language - interpreted language for
      measuring data in SFS files; SPC Speech Pascal - compiled
      language for waveform manipulation and analysis; C-SPAN -
      compiled language for synthetic speech stimuli generation.
