files, similar to a traditional dictation machine. The
<em class="replaceable"><code>base_dir</code></em> parameter specifies the directory in
which Asterisk will write the recorded files. If not specified, it
defaults to the <span class="emphasis"><em>dictate</em></span> subdirectory of the
Asterisk spool directory (as defined in <code class="filename">asterisk.conf</code>).</p><p>If the <em class="replaceable"><code>filename</code></em> 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.</p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p>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 <code class="literal">sox</code>,
or use the <code class="literal">file convert</code> command
from the Asterisk command-line interface.</p></div><p>The <code class="literal">Dictate()</code> application has
two main modes: recording mode and playback mode. The caller can press
the <code class="literal">1</code> key to switch between these
modes. In both modes, the <code class="literal">0</code> key can
be used to get help. The <code class="literal">*</code> key is
used to pause or unpause the recording or playback. The <code class="literal">#</code> key allows the caller to choose a new
filename.</p><p>In recording mode, the <code class="literal">8</code> key
can be used to erase the entire recording and start over.</p><p>In playback mode, the <code class="literal">7</code> key
rewinds the recording a few frames, and the <code class="literal">8</code> key forwards the recording a few frames. The
<code class="literal">2</code> key is used to toggle the playback
speed (either 1x, 2x, 3x, or 4x).</p><a id="I_programlisting_tt2175"></a><pre class="programlisting">; begin dictating, and save the files in the /tmp/dictate directory
