sentence/phrase boundaries, neighboring pauses and punctuation) For each word in the AMI corpus, we obtained two alternative estimates of word duration: one version which is independent of a word's sentential context, and a second version which does take into account the sentential context (such as phrasal/sentential and across-word-boundaries phonological features) the word occurs in.
we obtain MARY word duration estimates in the second version by running individual whole sentences through MARY, segmented by standard punctuation marks used in the AMI corpus transcriptions.
