GENERAL OPTIONS

21       The following options may be used in either dial or recognition mode:
22
23       -audio servername
24               This  option specifies the Network Audio System server on which
25               the files should be played.
26

DIAL OPTIONS

28       The following options may be used in dial mode:
29
30       -volume 0-100
31               This option specifies the volume at which the  data  should  be
32               played  as  a  percentage  of the maximum possible volume.  The
33               default is 100 percent.
34
35       -spacing milliseconds
36               This option specifies the number of  milliseconds  to  wait  in
37               between each digit.  The default is 100.
38
39       -pause milliseconds
40               This  option specifies the number of milliseconds to wait when‐
41               ever a comma (,) is used in a dial string.  The default is 400.
42
43       -duration milliseconds
44               This option specifies the duration of each  tone  in  millisec‐
45               onds.  The default is 100.
46

DIALING STRING

48       The following characters may be used in a dialing string:
49
50       0123456789*#
51               The corresponding touch tone is generated.
52
53       abcd    Tones  representing the 4 "function" keys often found on a key‐
54               pad are generated.
55
56       ,       A blank tone whose length is specified by the -pause option  is
57               generated.
58
59       Any other characters are ignored.
60

RECOGNITION OPTIONS

62       -recognize
63               Enables  recognition  mode.   audial  will attempt to recognize
64               touch tones from the input device and output the  corresponding
65               character.
66
67       -microphone
68               Use  microphone  gain  levels  on the audio input device.  If a
69               microphone is plugged into the audio input  jack,  this  option
70               should be used.
71
72       -gain 0-100
73               This option specifies the input gain level.  The default is 95.
74
75       -time seconds
76               This option specifies how long to attempt the recognition.  The
77               default is forever.
78
