NAME
     soft - JSRU parallel-formant speech synthesizer

SYNOPSIS
     soft (-I) (-x|-X|-r) (-i item) (-p parfil) (-g glotfil) (-l)
     (-f female) (-e extended formants) (-t stat_table) file

DESCRIPTION
     soft is a  software  implementation  of  a  parallel-formant
     speech synthesizer.  It is a new "C"-language implementation
     of the FORTRAN software synthesizer of JSRU report 1016.

     An SY item in the source file file is  converted  to  an  SP
     item and written back to file.

     Options and their meanings are:

     -I   Identify program name and version number, then exit.

     -pparamfile
                Use the parameter file paramfile instead  of  the
                default  parameter file.  More information on the
                parameter file may be found in parfil(5).

     -gglottalfile
                Read the glottal pulse  shape  and  glottal  area
                from  the file glottalfile instead of the parame-
                ter file.  The format for a glottal  file  is  an
                ASCII  file  containing  two  lists  of  integers
                separated by  spaces.   The  first  list  has  72
                entries  in the range -127 to +127 and represents
                the glottal pulse shape.  The second list has  18
                entries  in  the range 0 to 15 and represents the
                glottal area.

     -x         Write the excitation waveform and glottal area to
                the  database  file dbasefile. The excitation and
                glottal area waveforms are written as LX items.

     -r         Read the excitation  waveform  and  glottal  area
                from  the database file dbasefile which must con-
                tain two LX items.  The first is  assumed  to  be
                the   excitation,  the  last  the  glottal  area.
                Selection of input waveforms can  be  over-ridden
                by  item selections for LX: the first for excita-
                tion, the second for glottal area.

     -iitem     Select input item number.

     -l         List the parameters and  tables  configuring  the
                synthesizer to standard output and exit.

     -X         Generate the excitation and  glottal  area  only.
                No  speech item is generated. The excitation item
                and the glottal area item are written back to the
                database file dbasefile.

     -f         With this flag included the AHF formant is placed
                at 4200 Hz.

     -e         This flag  includes  formants  at  3500Hz  4200Hz
                5200Hz.

     -t stat_table
                Use OP stat table file (produced  by  inlx(1)  or
                statlx(1))

FILES
     SFSBASE/data/nparfil - default parameter file.
