I have the same setup as Broadcastify Calls (trunkrecorder) and a site built to play each audio recording then allow the user to provide what they heard. I used it to train some public safety specific models on Kaldi and Sphinx. I have 30ish streams and keep 6 days worth, I could keep longer if you'd like to work together on this. I reached out to some of the people above, the Broadcastify guy for example, and they are, as mentioned, ready doing their own thing so didn't really care about what I wanted to share.
