Is there a way to make Alexa give some kind of "in progress" sound or the ability to say a "please wait" message before real responses get sent from our service back to Alexa?
We know that we might be taking long for certain operations to complete before sending back JSON responses, and so we're developing knowing that these conversations aren't going to be 100% snappy. I'm looking for some kind of indicator to the user that we / Alexa is working on getting the right answer, instead of having awkward extended pauses here and there.
> 1. [welcome message JSON passed from us to Alexa] => Alexa: "What would you like to do?"
> 2. User: (some intent) => [intent request sent from user to Alexa, then Alexa to us]
> 3. [long pause due to long operation, ends with us passing answer JSON to Alexa] => Alexa: (answer)
Is there a way to have a "pre-response" that sits in between 2 and 3?
