Oh , the other thing I guess which  which , uh , I don't know much about  as much as I should about the rest of the system but  but , um , couldn't you , uh , if you  if you sort of did a first pass I don't know what kind of , uh , uh , capability we have at the moment for  for doing second passes on  on , uh , uh , some kind of little  small lattice , or a graph , or confusion network , or something. But if you did first pass with , um , the  with  either without the mean sub subtraction or with a  a very short time one , and then , um , once you , uh , actually had the whole utterance in , if you did , um , the , uh , uh , longer time version then , based on everything that you had , um , and then at that point only used it to distinguish between , you know , top N , um , possible utterances or something , you  you might  it might not take very much time. I mean , I know in the large vocabulary stu uh , uh , systems , people were evaluating on in the past , some people really pushed everything in to make it in one pass but other people didn't and had multiple passes. And , um , the argument , um , against multiple passes was u u has often been " but we want to this to be r you know  have a nice interactive response ". And the counterargument to that which , say , uh , BBN I think had ,  was " yeah , but our second responses are  second , uh , passes and third passes are really , really fast ".
Mm - hmm.
So , um , if  if your second pass takes a millisecond who cares ? Um.
S so , um , the  the idea of the second pass would be waiting till you have more recorded speech ? Or  ?
