How to make Rasa echo/repeat user input utterance

Hi, I’m using a custom web server to take some video as input and convert the visual information into something Rasa can understand. Sometime I need to process the visual input in the server and generate an unique expected response. Since there are too many possible response so I want to do this in the server instead of let Rasa generate the response. By doing this I want to generate a response to Rasa and let Rasa simply echo/repeat this response. I found it hard to do using the standard Rasa actions. Can anyone give some advice? Thank you.

Hi @YZZ, what you are looking for is a custom NLG server . :slight_smile:
