The Relationship Between Dialogue Acts and Hot Spots in Meetings
We examine the relationship between hot spots and dialogue acts in roughly 32 hours of speech data from naturally-occurring meetings. Results reveal that four independently-motivated involvement categories (non-involved, disagreeing, amused, and other) show statistically significant associations with particular DAs.

RegReg: a Lightweight Generator of Robust Parsers for Irregular Languages
We present a lightweight tool, called RegReg, based on a hierarchy of lexers described by tagged regular expressions. By using tags, the automatically generated parse tree can be easily manipulated.

Modeling Duration Patterns for Speaker Recognition
We present a method for speaker recognition that uses the duration patterns of speech units to aid speaker classification. The approach represents each word and/or phone by a feature vector comprised of either the durations of the individual phones making up the word, or the HMM states making up the phone.

Spotting “Hot Spots” in Meetings: Human Judgments and Prosodic Cues
Recent interest in the automatic processing of meetings is motivated by a desire to summarize, browse, and retrieve important information from lengthy archives of spoken data. One of the most useful capabilities such a technology could provide is a way for users to locate “hot spots” or regions in which participants are highly involved in…

Automatic Disfluency Identification in Conversational Speech Using Multiple Knowledge Sources
This work investigates a number of knowledge sources for disfluency detection, including acoustic-prosodic features, a language model (LM) to account for repetition patterns, a part-of-speech (POS) based LM, and rule-based knowledge.

Nucleotide sequence based characterizations of two cryptic plasmids from the marine bacterium Ruegeria isolate PR1b
Given the nature of the putative proteins encoded by both plasmids it is possible that these plasmids enhance the metabolic and physiological flexibility of the host bacterium, and thus its adaptation to the marine sediment environment.
