Assign default behavior
Learn how to adjust the out-of-the box behaviors for your conversational application in your NLX workspace
What's the Default behavior tab of an application?
Default behaviors define which conversation flows the application should follow in specific situations. This includes how the conversational AI application initially greets the user as well as how it responds to technical issues or unknown user responses.
Required default behaviors
Open the application you wish to edit and select the Default behavior tab. A few behavior types that are always enabled for an application include:

Welcome: What your application follows when a conversation session is initialized
Unknown: What your application follows when incomprehension occurs (inability to understand the user's response). You may assign a Knowledge base from your workspace to the Unknown default; this allows your application to check the knowledge repository for a response to a common question without the need for a dedicated intent flow.
Optional behavior types
Optional behaviors are disabled by default, but you may enable and edit these for your conversational AI:
Help: When a user expresses they are in an emergency situation
Frustration: When a user expresses frustration
Escalation: When an escalation process is triggered
Repeat: When a user requests the last message be repeated
Resume: When a user requests a pause before continuing the conversation
Quick reply vs flow
For most behavior types, you may toggle between a built-in quick reply or custom flow.
NLX provides quick reply phrases, but it's recommended that you create custom flows for handling all mandatory behavior types.
Quick replies allow you to enter the phrase the conversational AI delivers to the user in a particular situation.
At least one phrase is required for the behavior to work in this mode. Additional phrases can be added for variety by choosing Add quick reply. You can remove a phrase by clicking on the remove icon.
