Demystify the art of designing Siri experiences for your music and audio apps: We’ll show you how to think about crafting great interactions and how you can provide custom vocabulary so that Siri can respond with more accuracy and personality. We’ll also explain how you can debug common errors and test your intents using the same methods Apple’s own Siri team employs.
