hello.
my name is sarwat nasir and i m working on a speaker recognition project.the underlaying idea is that humans can recognise speakers by the diff in there pronounciations even if they dont understand what he is speaking about. for that purpose i need a presegmented speech(segmented into phonemes).
any information to this ll b highly appreciated
regards
sarwat
