  • Model Transformation for Robust Speaker Recognition from Telephone Data

    In the context of automatic speaker recognition, we propose a model transformation technique that renders speaker models more robust to acoustic mismatches and to data scarcity by appropriately increasing their variances.

  • HTTP://WWW.SPEECH.SRI.COM/DEMOS/ATIS.HTML

    This paper presents a speech-enabled WWW demonstration based on the Air Travel Information System (ATIS) domain. SRI’s speech recognition technology and natural language understanding are fully integrated in a Java application using the DECIPHER(TM) speech recognition system and the Open Agent Architecture(TM).

  • Acoustic Modeling for the SRI Hub4 Partitioned Evaluation Continuous Speech Recognition System

    We describe the development of the SRI system evaluated in the 1996 DARPA continuous speech recognition (CSR) Hub4 partitioned evaluation (PE). The task for the Hub4 evaluation was to recognition speech from broadcast television and radio shows.

  • Hub4 Language Modeling Using Domain Interpolation and Data Clustering

    In SRI’s language modeling experiments for the Hub4 domain, three basic approaches were pursued: interpolating multiple models estimated from Hub4 and non-Hub4 training data, adapting the language model (LM) to the focus conditions, and adapting the LM to different topic types.

  • On the determination of epipoles using cross-ratios

    We study the problem of computing the position of the epipoles in a pair of uncalibrated images. The approach, which is based on the invariance of the cross-ratio by the epipolar transformation

  • Role Of Technology In Student-Scientist Partnerships: Perspective From The National Science Foundation

    Abstract A variety of student-scientist partnerships (SSPs) have evolved over the years in the K-12 classroom, providing students, teachers, and scientists with activities and experiences not available from any other source. Characteristically these activities are inquiry-based or design-oriented and aligned with Benchmarks (American Association for the Advancement of Science, 1993), (National Research Council of the National Academy…

  • Transducer Placement for Broadband Active Vibration Control Using a Novel Multidimensional QR Factorization

    This paper advances the state of the art in the selection of minimal configurations of sensors and actuators for active vibration control with smart structures. This paper presents the development of the method, as well as its application in active vibration control of a plate.

  • A chemical assessment and HPLC assay validation of bulk paromomycin sulfate

    This paper describes the compositional analyses of four paromomycin sulfate samples and features a validated HPLC assay method that relies on the fluorescence detection of isoindole derivatives of paromomycin, formed by post-column reaction with o-phthalaldehyde and 2-mercaptoethanol.

  • Many Robots Make Short Work

    Abstract Indoor mobile robots are becoming reliable enough in navigation tasks to consider working with teams of robots. Using SRI International’s open-agent architecture (OAA) and SAPHIRA robot-control system, we configured three physical robots and a set of software agents on the internet to plan and act in coordination. Users communicate with the robots using a…

  • The Radius Common Development Environment

    The application focus of RCDE is on image exploitation where the exploitation tasks are supported by 2D and 3D models of the geographic site being analyzed

  • Globe Year 2 Evaluation: Implementation And Progress

    GLOBE views the Earth as a dynamic system, with special attention to mapping and understanding patterns in the arts of Atmosphere, Hydrology, Land Cover/ Biology, Soil, and Global Positioning Systems (GPS).
