I would like to play a short sound for a more amusing output. If I understand the documentation correctly it should be possible with a reply in api.ai of something like this SSML:
<speak>Okay here we go: <audio src="http://example.com/boing.wav">boing</audio>. You are welcome!</speak>
Just for reference SSML means Speech Synthesis Markup Language.
The web simulator don't play this sound instead all tags seems to be stripped out. Is that not supported yet or did I do something wrong?
The src URL must also be an https URL (Google Cloud Storage can host your audio files on an https URL).
