Dictate() — Virtual dictation machine
This application allows the recording and playback of
files, similar to a traditional dictation machine. The
base_dir parameter specifies the directory in
which Asterisk will write the recorded files. If not specified, it
defaults to the dictate subdirectory of the
Asterisk spool directory (as defined in asterisk.conf).
If the filename parameter is specified,
it will be used when the file is written. If not specified, Asterisk
will prompt the caller for a numeric filename for the file.
Asterisk writes the files in raw, headerless, signed-linear
format. If you’d like to convert the file to another format, you can
use an outside utility such as sox,
or use the file convert command
from the Asterisk command-line interface.
The Dictate() application has
two main modes: recording mode and playback mode. The caller can press
the 1 key to switch between these
modes. In both modes, the 0 key can
be used to get help. The * key is
used to pause or unpause the recording or playback. The # key allows the caller to choose a new
filename.
In recording mode, the 8 key
can be used to erase the entire recording and start over.
In playback mode, the 7 key
rewinds the recording a few frames, and the 8 key forwards the recording a few frames. The
2 key is used to toggle the playback
speed (either 1x, 2x, 3x, or 4x).
