This is incredible!<p>While we were trying to build up a corpus of transcription data for our company, I often thought we should build something like this an open-source it. We ended up building a one-off hacked-up thing to do it instead, but I'm really glad this exists for any future people in our shoes.<p>Annotating speech data is super tedious and anything that improves the process even 10% is a huge, huge win.
