1)  Pick your audio output device.  This will almost certainly involve some sort of D/A conversion, as well as appropriate other EE magic to get a speaker of some sort to make noise.&lt;br /&gt;
&lt;br /&gt;
2) Write code to drive your D/A converter from sampled digital sound stored in your microcontroller memory.  You&amp;#39;ll need to pick a storage format: maybe just straight sampled data, maybe compressed (MP3?).&lt;br /&gt;
&lt;br /&gt;
3) Choose someone whose voice you like (perhaps a professional voice actor, even), and sample their voice while they read all the possible things you want your system to say.  You&amp;#39;ll probably need to save space by storing just fragments of the output.  That is, you&amp;#39;d probably have the sounds &amp;quot;March&amp;quot;, &amp;quot;3&amp;quot;, and &amp;quot;2003&amp;quot;, rather than one big &amp;quot;March 3, 2003&amp;quot;, so that you can get by with 12 month samples and 31 day samples rather than 365 samples to name every day of the year.&lt;br /&gt;
&lt;br /&gt;
You&amp;#39;ll get to make some quality/cost tradeoffs here.  It&amp;#39;s better to have your system use more natural phrases like &amp;quot;twelve thirty&amp;quot; instead of &amp;quot;twelve and three zero minutes&amp;quot;, but you&amp;#39;ll need more samples and a bit smarter code to do more than just read out the digits.&lt;br /&gt;
&lt;br /&gt;
4) Write your application to read your TOD clock, and then output the appropriate fragments of sounds through the D/A.&lt;br /&gt;
&lt;br /&gt;
Details are left as an exercise for the reader.&lt;br /&gt;
