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,…

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…

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…

Spatial Temporal and Histogram Video Registration for Digital Watermark Detection
In this paper, we propose a spatial, temporal and histogram (STH) registration algorithm for video sequences. This algorithm is developed based on a frame-level model of the misalignments often introduced…
