Word Predictability After Hesitations: A Corpus-based Study
We ask whether lexical hesitations in spontaneous speech tend to precede words that are difficult to predict. We define predictability in terms of both transition probability and entropy, in the…

Handling Compound Nouns in a Swedish Speech-Understanding System
This paper describes and evaluates a simple and general solution to the handling of compound nouns in Swedish and other languages in which compounds can be formed by concatenation of…

Disfluencies in Switchboard
Disfluencies are prevalent in spontaneous speech, and are relevant to both human speech communication and speech processing by machine. This paper reports selected results on Switchboard and two comparison corpora…

Unusual ribulose-1,5-bisphosphate carboxylase/oxygenase genes from a marine manganese-oxidizing bacterium
Initial DNA hybridization screening showed that SI85-9A1 possesses a gene similar to cbbL, the gene coding for the large subunit of ribulose-1,5-bisphosphate carboxylase/oxygenase (RubisCO; EC 4.1.1.39). However, no RubisCO enzyme activity was…

Using Crest Line to Guide Surface Reconstruction from Stereo
We propose an approach to interleave surface reconstruction from multiple images and feature extraction using object-centered representation optimized to conform to the surface shape.

Modeling Pitch Range Variation Within and Across Speakers: Predicting F0 Targets when “Speaking Up”
We study F0 variation produced by "speaking up", as part of a larger study of pitch range variation within and across speakers. We provide a function to predict target F0…

Acoustic Adaptation Using Non-Linear Transformations of HMM Parameters
Speech recognition performance degrades significantly when there is a mismatch between testing and training conditions. Linear transformation-based maximum-likelihood (ML) techniques have been proposed recently to tackle this problem. In this…

Segmenting Reactions to Improve the Behavior of a Planning/Reacting Agent
In this paper, we examine the problem of selecting the best set of reactions for an agent to store. In particular, we examine the benefit of including {em intervals} of…
