Mmm.
Um , I did some  experim uh , uh , just a few more experiments before I had to ,  uh , go away for the w well , that week.
Great !
Was it last week or whenever ? Um , so what I was started playing with was the  th again , this is the HTK back - end. And , um , I was curious because the way that they train up the models ,  they go through about four sort of rounds of  of training. And in the first round they do  uh , I think it 's three iterations , and for the last three rounds e e they do seven iterations of re - estimation in each of those three. And so , you know , that 's part of what takes so long to train the  the  the back - end for this.
