You know ? If something is kind of like the equivalent of a bunch of probabilities multiplied together , you can take a root of some sort. If it 's like seven probabilities together , you can take the seventh root of it or something , or if it 's in the log domain , divide it by seven.
Mm - hmm.
But  but , um , that has a similar effect because it changes the scale of the numbers  of the differences between different candidates from the acoustic model
Oh , right.
