个人简介
In the late 1980s, his work focused on the evaluation of early speech-to-text continuous speech transcription systems (formerly referred to as automatic speech recognition) in the context of a number of DARPA programs. His work on corpus and evaluation-driven research and development helped to significantly speed progress in this technology. In the 1990s, he extended his work to the evaluation of speech understanding systems in the DARPA ATIS and Communicator programs and, in the late 1990s, to information retrieval applied to speech in the TREC Spoken Document Retrieval Track. He saw multimodality as a key challenge for the future and spearheaded the construction of a massively instrumented multimodal/multichannel meeting room. The data collected in the room has been used in a variety of speech and computer vision evaluations and the project inspired two European programs focused on multimodality. In 2004, he began working with the Video Analysis and Content Extraction Program under what is now IARPA to port approaches used in speech technology evaluation to the computer vision domain. He developed an extensive corpus and metrics-based evaluation framework for video object detection and tracking technologies, as well as video text recognition technologies in collaboration with the University of South Florida. He is currently the manager of the NIST Speech Technologies Group and oversees a number of human language and computer vision technology evaluation activities. He continues to reach to bring his knowledge of evaluation-driven research and development to new technology communities.
