Speech Synthesis Markup

<speak>
  So next you're going to tell them how to use
  Speech Synthesis Markup Language or
  <say-as interpret-as='characters'>SSML</say-as>
  to shape the persona by doing things such as
  <prosody rate='slow'>
    inserting <break time='0.5s'/>
    dramatic <break time='0.5s'/>
    pauses. <break time='1s' />
  </prosody>
  Or making noises
  <audio src='https://actions.google.com/sounds/v1/cartoon/cartoon_boing.ogg'/>
  <prosody rate='fast'>Or talking very quickly.</prosody>
  <prosody pitch='high'><voice gender='male' variant='2'>Or even changing</voice></prosody>
  <prosody pitch='low'><voice gender='female' variant='2'>my voice</voice></prosody>
