Discriminative Training of Minimum Cost Speaker Verification Systems
This paper presents a new training procedure for speaker verification systems. Results are presented from the 1997 NIST Speaker Recognition Evaluation corpus indicating that the VCF performance can be improved with this procedure.

Connecting With The Twenty-First Century: Technology In Support Of Educational Reform
We present an alternative image of what schools might be like and a set of interlocking social, pedagogical and technological changes that could transform the educational enterprise.

Hybrid Planning: An Approach to Integrating Generative and Case-Based Planning
This paper describes ongoing research on the development of a hybrid planning system that integrates case-based reasoning (CBR) methods into SIPE-2, a generative planning system.

Can Prosody Aid the Automatic Classification of Dialog Acts in Conversational Speech?
This study asks whether current approaches, which use mainly word information, could be improved by adding prosodic information. The study is based on more than 1000 conversations from the Switchboard corpus.

The Mathematics Of Change And Variation From A Millennial Perspective: New Content, New Context
We shall examine large-scale trends in content changes and in context changes for learning and using mathematics. From this set of factors, we raise three questions.

Automatic Detection of Discourse Structure for Speech Recognition and Understanding
We describe a new approach for statistical modeling and detection of discourse structure for natural conversational speech. Our model is based on 42 `Dialog Acts’ (DAs), (question, answer, backchannel, agreement, disagreement, apology, etc).

Using Information Extraction to Improve Information Retrieval
The authors describe an approach to applying a particular kind of Natural Language Processing NLP system to the TREC routing task in Information Retrieval IR.

A Prosody-Only Decision-Tree Model for Disfluency Detection
We have developed a disfluency detection method using decision tree classifiers that use only local and automatically extracted prosodic features. Because the model doesn’t rely on lexical information, it is widely applicable even when word recognition is unreliable.

Acoustic Clustering and Adaptation for Robust Speech Recognition
We describe an algorithm based on acoustic clustering and acoustic adaptation to significantly improve speech recognition performance. The method is particularly useful when speech from multiple speakers is to be recognized and the boundary between speakers is not known.
