The idea behind fallback intents is mostly the same as how they are defined in Dialogflow. There are two kinds – the “catch-all” fallback intent without any input context and the “context-based” fallback intent which does have an input context.
I explain more in the video below:
Autogenerated YouTube transcript[00:00] now that we have seen the idea behind candidate intents and target intents we are going to look at the next type which is the fallback intents and this is quite straightforward the fallback intents I am referring to are actually pretty much the same as the fallback intents that Dialogflow already provides us. For example this is the default fallback intent which has no input context set and these are the context based fallback intents [00:30] well you do have an input context set and if that input context is set. And the user says something that can not be identified it automatically goes to these fallback intents that’s the that’s pretty much the purpose of these fallback intents.
And the idea is if you have an intent which you would like to fire at a specific step in the conversation the case where you don’t handle the input like if you if the user ⌛ [01:00] types something which you did not expect or you are not able to handle that should automatically trigger the fallback intent for that specific step in the conversation in some situations it will be the default fallback intent which will fire if
