+<h2>The media type 'aural'</h2>

+<p>We expect that in a future level of CSS there will be new
+properties and values defined for speech output. Therefore
+CSS&nbsp;2.1 reserves the 'speech' media type (see <a
+href="media.html">chapter 7, "Media types"<a/>), but does not yet
+define which properties do or do not apply to it.

+<p>The properties in this appendix apply to a media type 'aural', that
+was introduced in CSS2. The type 'aural' is now deprecated.

+<pre>
+@media speech {

+@media aural {
+  body { voice-family: Paul }
