The intonation model of the present technology disclosed herein assigns different words within a sentence to be prominent, analyzes multiple prominence possibilities (in some cases, all prominence possibilities), and learns parameters of the model using large amounts of data. Unlike previous systems, intonation patterns are discovered from data. Speech data is sub-segmented into words, the different segments are analyzed and used for learning, and a determination is made as to whether the segmentations predict pitch
