ABSTRACT
Three male American English talkers spoke words that
differed in lexical stress, and sentences that differed in
phrasal stress, while video and movements of the face were
recorded. In a production study, stressed vs. unstressed
syllables from these utterances were compared along many
measures of facial movement, which were generally larger
