Creating a Custom Slot Type for Yes/No Responses in AWS Lex

hi Sophie, you can define a custom slot with your name like YesOrNo, then your choose Expand Values(this is the referred one), you can also use Restrict to slot values if you have lots of training data from your previous chat logs.

then in your flow design, you can use the condition like if {yourslot} = yes or no to implement different branches.

hope that helps.
