Automatic Discovery of Simply-Composable Prosodic Elements

Speech Prosody 2014

Nigel G. Ward

Abstract: As a way to discover the elements of prosody, Principal Component Analysis was applied to several dozen contextual prosodic features, sampled at 600,000 timepoints in dialog data. The resulting components are interpretable as prosodic patterns, including some which involve behaviors of both interlocutors. Examining contexts and co-occurring words, many of these have clear interpretations. This suggests that English has at least several dozen prosodic patterns, each with its own communicative function.
