  • Voice recognition system using implicit speaker adaptation
    Publication number: 20020143540
    Abstract: A voice recognition (VR) system is disclosed that utilizes a combination of speaker independent (SI) and speaker dependent (SD) acoustic models. At least one SI acoustic model is used in combination with at least one SD acoustic model to provide a level of speech recognition performance that at least equals that of a purely SI acoustic model. The disclosed hybrid SI/SD VR system continually uses unsupervised training to update the acoustic templates in the one or more SD acoustic models.

  • System and method for hybrid voice recognition
    Publication number: 20020091522
    Abstract: A method and system for voice recognition combines different types of voice recognition (VR) engines in order to recognize user-defined digits and control words, predefined digits and control words, and nametags. Speaker-independent VR engines are combined with speaker-dependent VR engines. A Hidden Markov Model (HMM) VR engine is combined with Dynamic Time Warping (DTW) engines.
