language because it's produced by you know people it kind of is naturally designed to be very clean and very high-level and yeah it removes all the noise so when I think we run and try to train the same generative models or approaches in domains like images or video it may just be that like when you're dealing with raw natural audio signals are you know sorry not raw natural signals they have so much noise like particularly a likelihood based generative model is just like spending so much effort and capacity trying to predict all that
