Listen

The Listen action instructs the Assistant to wait for user input, keeping the dialogue alive. If there is no Listen action the dialogue will end.

The Listen action can have one property: tasks, that allows you to constrain the listen to a subset of tasks.

On messaging channels (including SMS, Chat, FB Messenger, or Slack), the Listen action will wait for user response for 4hrs. If there is no user response the dialogue will timeout.

The Listen action has one optional property:

Example 1: Ask a question and wait for an answer

{
	"actions": [
		{
			"say": {
				"speech": "Hello! how can I help you"
			}
		}, {
		    "listen":true
		}
	]
}

In the above example, the Assistant will ask the question and keep the dialogue open waiting for an answer.

Example 2: Constrain the listen to a subset of tasks

With the tasks property, you can constrain the tasks that the Assistant listens to.

{
	"actions": [
		{
			"say": {
				"speech": "What would you like to do? Continue shopping or check out?"
			}
		},
		{
			"listen": {
				"tasks": [
					"search-for-product",
					"checkout"
				]
			}
		}
	]
}
