So , in fact , it 's a little hard because recognizers , to first order , sort of work. And the reasons we 're doing the things we 're doing is because they don't work as well as we 'd like. And since they sort of work , uh , it means that they are already doing  if you go and take any recognizer that 's already out there and you say , " how well is it distinguishing between  schwas and stops ? "
Mm - hmm.
Boy , I bet they 're all doing nearly perfectly on this , right ?
Mm - hmm.
