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

       The following options may be used in dial mode:

       -volume0-100
               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.

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

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

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

       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.

       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.

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

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

-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.

       -gain0-100
               This option specifies the input gain level.  The default is 95.

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