Fin's auto classificate during a conversation

Today i have a really big problem with auto classifications. The new functionallity allow us to call by workflow the auto classificate attributes, but its not happen when a customer is talking with the Fin. Its results to me “non classifications” in conversations that the user comes just talking “Hi, hello, good afternoon” and stuffs like this. My dream is Fin can auto classificate these attributes while is talking with customer because theres no other time to classificate the attributes in jus fin conversation.
