Data-Driven Subclassification of Disfluent Repetitions Based on Prosodic Features
This study delves into the acoustic and prosodic information of repetitions, one of the most common disfluencies. A hierarchical clustering of prosodic features reveals three subsets of repetitions, each reflecting…

Phonetic Consequences of Speech Disfluency
Analyses of American English show that disfluency affects a variety of phonetic aspects of speech, including segment durations, intonation, voice quality, vowel quality, and coarticulation patterns. These effects provide clues…

Modeling the Prosody of Hidden Events for Improved Word Recognition
We investigate a new approach for using speech prosody as a knowledge source for speech recognition. The idea is to penalize word hypotheses that are inconsistent with prosodic features such…

Combining Words and Prosody for Information Extraction from Speech
In this work we demonstrate the use of em prosodic cues, alone and in combination with words, for segmentation and name finding. In experiments, we find that prosodic cues alone…

Characterizing the Performance of Multiple-Image Point-Correspondence Algorithms using Self-Consistency
A new approach to characterizing the performance of point- correspondence algorithms is presented.

Robust Text-Independent Speaker Identification over Telephone Channels
This paper addresses the issue of closed-set text-independent speaker identifcation from samples of speech recorded over the telephone. It focuses on the effects of acoustic mismatches between training and testing…

Performance Assessment Links In Science (PALS)
SRI International is developing Performance Assessment Links in Science (PALS), an on-line, standards-based, interactive resource bank of science performance assessments.

Finding Consensus Among Words: Lattice-based Word Error Minimization
We describe a new algorithm for finding the hypothesis in a recognition lattice that is expected to minimize the word error rate (WER). Our approach thus overcomes the mismatch between…

At the Boundary of Workflow and AI
This paper describes how techniques from the AI community, specifically reactive control, planning, and scheduling, could be leveraged to develop powerful, next-generation adaptive workflow engines that provide many of the…

Task-based Information Management
We are constructing a system, called the Task-based Information Distribution Environment (TIDE), that delivers information to participants in a dynamic collaboration by evaluating the relevance of incoming and newly generated…
