Yeah.
OK. Um , and , um ,  the other thing , uh , which I 'll just say very briefly that maybe relates to that a little bit , which is that , um , uh , one of the suggestions that came up in a brief meeting I had the other day when I was in Spain with , uh , Manolo Pardo and  Javier , uh , Ferreiros , who was  here before , was , um , why not start with what they had before but add in the non - silence boundaries. So , in what Javier did before when they were doing , um  h he was looking for , uh , speaker change  points.
Mm - hmm.
Um. As a simplification , he originally did this only using  silence as , uh , a  putative , uh , speaker change point.
