title: Google assistant service, how to filter multiple audio responses
body: <p>It's hard to explain but in fact I m trying to code my own library with The Google Assistant Service.</p>
  
  <pre><code>me &gt; "set a timer"
  GA &gt; "sure, how long"
  me &gt; "10 mn"
  GA &gt; "ok, timer is set" (1st response)
  GA &gt; "Sorry I can't help you" (2nd response)
  </code></pre>
  
  <p>The reaction is normal, because service don't support timer. I want to code my own timer, but no way to keep the first response and block the second. <strong>dialog_state_out.supplemental_display_text</strong> contain only the first one, but the audio core play all the data we have in <strong>audio_out.audio_data</strong>.</p>
  
  <p>How to separe the 2 responses, I don't see disconnection on the data flow and only 1 request done.</p>
