delay after user provides an answer to a question and then alexa asking the next question /

I absorb an Intent that has multiple slots and each time the user provides the information for a slot,Alexa would prompt for the acknowledge to the next slot.
Unfortunately, what I absorb experienced is a long 6 second delay between the user telling Alexa the information and Alexa asking for the next slot value.
Has anyone experienced this behaviour before?
