Storing Transcripts from the Interactive Avatar

I've been attempting to utilize the demo as a starting point which I have been able to get working and is doing great. My main goal which will determine if we invest in the solution is to receive a transcript from the conversations. I have been able to log the avatars responses but I am struggling to store the users transcripts. Is there a working project that I could learn from that stores the transcripts or am I able to get some help on my attempt at all?
