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.
