Um , the sort of standard answer about this sort of thing is that if you 're trying to find  the right system in some sense , whether you 're trying by categories or  or parameters  um , and your goal is discrimination , then having choices based on discrimination as opposed to , um , unsupervised nearness of things , um , is actually better.
Hmm.
Um , and I don't know if that  I mean , since you 're dealing with issues of robustness , you know , maybe  maybe this isn't right , but it 'd be something I 'd be concerned about. Because , for instance , you can imagine , uh , uh , i i if you remember from  from , uh  from your  your quals , John Ohala saying that , uh , " buh "  and " puh "  differed , uh , not really cuz of voicing but because of aspiration. I mean , in as far as wha what 's really there in the acoustics.
