Development of the SRI/Nightingale Arabic ASR System
We describe the large vocabulary automatic speech recognition system developed for Modern Standard Arabic used for the 2007 GALE evaluation as part of the speech translation system.

The case for automatic higher-level features in forensic speaker recognition
We provide an overview of automatic higher-level systems and discuss potential advantages, as well as issues, for their use in the forensic context.

Modeling prior belief for speaker verification SVM systems
In this paper we propose to relax the assumption that the covariance matrix is the identity matrix, allowing it to be a more general block diagonal matrix. We show results…

Learning diagnostic models using speech and language measures
We describe results that show the effectiveness of machine learning in the automatic diagnosis of certain neurodegenerative diseases, several of which alter speech and language production. We analyzed audio from…

Model Driven Segmentation of Articulating Humans in Laplacian Eigenspace
We propose a general approach using Laplacian Eigenmaps and a graphical model of the human body to segment 3D voxel data of humans into different articulated chains. In the bottom-up…

Improving alignments for better confusion networks for combining machine translation systems
The state-of-the-art system combination method for machine translation (MT) is the word-based combination using confusion networks. One of the crucial steps in confusion network decoding is the alignment of different…

Using Semantic Features to Improve Task Identification in Email Messages
This paper addresses the lack of training data using domain-specific semantic features in document representation for reducing vocabulary mismatches and enhancing the discriminative power of trained classifiers.

Spoken language understanding—interpreting the signs given by a speech signal
Spoken language understanding (SLU) is the interpretation of signs conveyed by a speech signal. SLU and natural language understanding (NLU) share the goal of obtaining a conceptual representation of natural…

Applicability of Information Theory to the Quantification of Responses to Anthropogenic Noise By Southeast Alaskan Humpback Whales
We assess the effectiveness of applying information theory to the characterization and quantification of the affects of anthropogenic vessel noise on humpback whale (Megaptera novaeangliae) vocal behavior in and around…

Speech Segmentation and Spoken Document Processing
This article describes different levels of speech segmentation, approaches to automatically recovering segment boundary locations, and experimental results demonstrating impact on several language processing tasks.

Open-vocabulary spoken term detection using graphone-based hybrid recognition systems
We address the problem of retrieving out-of-vocabulary (OOV) words/queries from audio archives for spoken term detection (STD) task. In this work, we employ hybrid recognition systems which contain both words…
