Zusammenfassung
We investigate possible correlations between sentiment analysis scores obtained for sentences of Mark Twain’s novel ”The Adventures
of Tom Sawyer” and acoustic features extracted from the same sentences in the corresponding audiobook. We have found that scores
derived from movie reviews or categorisation of emotional stories seem to be more close to the acoustics in the narrative, in particular
more correlated with average energy and mean fundamental frequency (F0). We have designed an experiment intended to predict the
levels of acoustic expressivity in arbitrary text using sentiment analysis scores and the number of words in the text.
