This is exciting! If you look at historic speeches (ie from American Rhetoric http://www.americanrhetoric.com/top100speechesall.html http://www.americanrhetoric.com/top100speechesall.html), there are large variations in average characteristics between various styles/contexts (on average, pitch/volume/speed are different for inspirational vs somber speeches, for example). But there are also really large differences in the variation - an inspirational speech may be marked by large swings from quiet, reflective pieces to booming, rousing calls-to-action while a somber speech has fewer swings in delivery. For the examples given for various intonations from Obama/Trump, some intonations are much more natural than others. It would be interesting to decide how to parametrize a sentence for the intended intonation. (based on word2vec analysis of the words in the sentence, punctuation cues in the sentence, and perhaps a specified category of "emotional delivery"). It would be interesting at the sentence-level, but also at the macro speech-level to include the right "mix" of intonations for a specific context. On a related note, it would be interesting to study the patterns of intonations in successful vs unsuccessful outbound sales calls, for example, to learn how to best simulate a good human sales voice.
