Combining Discriminative Feature, Transform, and Model Training for Large Vocabulary Speech Recognition
This paper uses a state-of-the-art Mandarin recognition system as a platform to study the interaction of three techniques. Experiments in the broadcast news and broadcast conversation domains show that the…

Noise Robust Speaker Identification for Spontaneous Arabic Speech
We present an approach that integrates multiple components and models for improved speaker identification in spontaneous Arabic speech in adverse acoustic conditions.

Assessing Students. Performance Longitudinally: Item Difficulty Parameter Vs. Skill Learning Tracking
We are engaged in an effort to investigate if we can do a better job of predicting a large scale test (MCAS) by modeling individual skills in different grain-sized skill…

Unsupervised Language Model Adaptation for Meeting Recognition
We present an application of unsupervised language model (LM) adaptation to meeting recognition, in a scenario where sequences of multiparty meetings on related topics are to be recognized, but no…
-
Deductive Biocomputing
We describe a deduction-based approach to biocomputation that semiautomatically combines knowledge, software, and data to satisfy goals expressed in a high-level biological language.

NAP and WCCN: Comparison of Approaches Using MLLR-SVM Speaker Verification System
We compare two recently proposed techniques, within class covariance normalization (WCCN) [1] and nuisance attribute projection (NAP) [2], for intersession variability compensation in speaker verification.

Statistical Sentence Extraction for Information Distillation
In this paper, we present a statistical sentence extraction approach for distillation. Basically, we frame this task as a classification problem, where each candidate sentence in documents is classified as…

Designing For Design Learning
This paper highlights the need for a science of design to address the needs of technology design learners.

On-The-Move Independently Moving Target Detection
This paper describes a system for automatically detecting potential targets (that pop-up or move into view) and to cue the operator to potential threats. We present a 3D approach for…

Analysis of Morph-Based Speech Recognition and the Modeling of Out-of-Vocabulary Words Across Languages
We analyze subword-based language models (LMs) in large-vocabulary continuous speech recognition across four “morphologically rich” languages: Finnish, Estonian, Turkish, and Egyptian Colloquial Arabic.

Reliability of Adult Retrospective Recall of Lifetime Tobacco Use
The present analyses examined the test–retest reliability of retrospective tobacco use measures, including details of first use, circumstances of first use, and initial subjective reactions.

Speech Recognition as Feature Extraction for Speaker Recognition
We present specific techniques and results from SRI’s NIST speaker recognition evaluation system.
