One really easy way to do that is take your mic into a 741 op-amp.  Then
have a 555 clocking away at your favorite frequency for a voice.  Better yet,
put a potientiometer in to control the frequency.  Now grab an NPN x-sistor.
Connect the output of the op-amp to the base, the output of the 555 to the
collector, and then run the emitter to another op-amp.  What you end up
doing is AM'ing the signal from the 555.
