  <p>I haven't heard of anyone using a microphone yet, but you have a couple of options. 1) a USB sound card/microphone or 2) Bluetooth headset/hands-free device.</p>
  
  <p>The built-in speaker uses an alsa sound driver, so theoretically, it should work with any linux program.</p>
  
  <p>If you are looking at purchasing something USB, make sure it does not require USB 2.0. The USB port on the EV3 is USB 1.1 only.</p>
