NAME

       audial - generate or recognize touch tones for North American telephones

SYNOPSIS

       audial  [-audio  servername] [-volume 0-100] [-spacing milliseconds] [-pause milliseconds]
       [-duration milliseconds] dialstring

       audial -recognize [-microphone] [-gain 0-100] [-time seconds]

DESCRIPTION

       The audial program generates touch tones suitable for dialing a North American  telephone.
       audial can also recognize touch tones and produce the corresponding string.

GENERAL OPTIONS

       The following options may be used in either dial or recognition mode:

       -audio servername
               This option specifies the Network Audio System server on which the files should be
               played.

DIAL OPTIONS

       The following options may be used in dial mode:

       -volume 0-100
               This option specifies the  volume  at  which  the  data  should  be  played  as  a
               percentage of the maximum possible volume.  The default is 100 percent.

       -spacing milliseconds
               This  option  specifies  the number of milliseconds to wait in between each digit.
               The default is 100.

       -pause milliseconds
               This option specifies the number of milliseconds to wait whenever a comma  (,)  is
               used in a dial string.  The default is 400.

       -duration milliseconds
               This  option  specifies the duration of each tone in milliseconds.  The default is
               100.

DIALING STRING

       The following characters may be used in a dialing string:

       0123456789*#
               The corresponding touch tone is generated.

       abcd    Tones representing the 4 "function" keys often found on a keypad are generated.

       ,       A blank tone whose length is specified by the -pause option is generated.

       Any other characters are ignored.

RECOGNITION OPTIONS

       -recognize
               Enables recognition mode.  audial will attempt to recognize touch tones  from  the
               input device and output the corresponding character.

       -microphone
               Use  microphone gain levels on the audio input device.  If a microphone is plugged
               into the audio input jack, this option should be used.

       -gain 0-100
               This option specifies the input gain level.  The default is 95.

       -time seconds
               This option specifies how  long  to  attempt  the  recognition.   The  default  is
               forever.

ENVIRONMENT VARIABLES

       The following environment variables are used by audial:

       AUDIOSERVER
               This  specifies  the  name  of  default  audio  server  to  contact  if no name is
               explicitly given on the command line.

       DISPLAY This specifies the name of an X Window System display that should  be  assumed  to
               also have a corresponding Network Audio System server.
