Rate-dependent Acoustic Modeling for Large Vocabulary Conversational Speech Recognition
In this paper, we evaluate our approach on a large-vocabulary conversational speech recognition (LVCSR) task over the telephone, with several minimal pair comparisons based on different baseline systems.

A Survey of Research in Distributed, Continual Planning
In this article, we describe a new paradigm for planning in complex, dynamic environments, which we term distributed, continual planning (DCP). We argue that developing DCP systems will be necessary…

Coordinating Planning Activity and Information Flow in a Distributed Planning System
Distributed SIPE (DSIPE) is a distributed planning system that provides decision support to human planners in a collaborative planning environment.

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…

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…

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…
