This paper summarizes statistical modeling approaches for the use of prosody (the rhythm and melody of speech) in automatic recognition and understanding of speech. 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.

Keywords: Prosody, speech recognition and understanding, hidden Markov models.
