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:
The corresponding touch tone is generated.
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.
Enables recognition mode. audial will attempt to recognize touch tones from the input device and output the corresponding character.
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:
This specifies the name of default audio server to contact if no name is explicitly given on the command line.
This specifies the name of an X Window System display that should be assumed to also have a corresponding Network Audio System server.
