audial - generate or recognize touch tones for North American telephones
audial [-audio servername] [-volume 0-100] [-spacing milliseconds] [-pause milliseconds] [-duration milliseconds] dialstring audial -recognize [-microphone] [-gain 0-100] [-time seconds]
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 either dial or recognition mode: -audio servername This option specifies the Network Audio System server on which the files should be played.
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.
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.
-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.
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.
