We outline effective prosodic feature extraction, model architectures, and techniques to combine prosodic with lexical (word-based) information. We then survey a number of applications of the framework, and give results for automatic sentence segmentation and disfluency detection, topic segmentation, dialog act labeling, and word recognition.
