Text-based and Signal-based Prediction of Break Indices and Pause Durations.
Speech Prosody 2006, 2. - 5. Mai 2006, Dresden.
The relation between symbolic and signal features of prosodic
boundaries is experimentally studied using prediction methods.
Text-based break index prediction turns out to be fairly good,
but signal-based prediction and pause duration prediction perform worse. A possible reason is that random signal feature
variations, as usually produced by humans, are hard to predict.
