Modeling Dynamic Prosodic Variation for Speaker Verification
In this work, we take a first step toward capturing suprasegmental patterns for automatic speaker verification. Prosody modeling improves the verification performance of a cepstrum-based Gaussian mixture model system (as…

Lexical, Prosodic, and Syntactic Cues for Dialog Acts
This paper presents a preliminary investigation into the realization of a particular class of dialog acts which play an essential structuring role in dialog, the backchannels or acknowledgements tokens. We…

Controlling Communication in Distributed Planning Using Irrelevance Reasoning
This paper describes an approach to controlling information distribution among planning agents using irrelevance reasoning. We describe an implementation of this approach within a distributed version of the SIPE-2 planner.

Nonlinear Discriminant Feature Extraction for Robust Text-Independent Speaker Recognition
We study a nonlinear discriminant analysis (NLDA) technique that extracts a speaker-discriminant feature set. Our approach is to train a multilayer perceptron (MLP) to maximize the separation between speakers by…

Family Outcomes in Early Intervention: A Framework for Program Evaluation and Efficacy Research
In this article we suggest eight questions that could serve as a framework for determining the extent to which early intervention has accomplished the goals inherent in a family-centered approach.

Dialog Act Modeling for Conversational Speech
We describe an integrated approach for statistical modeling of discourse structure for natural conversational speech. Our model is based on 42 `dialog acts', which were hand-labeled in 1155 conversations from…
