We are exploring ways in which to rapidly adapt our neural network classi ers to new speakers and conditions using very small amounts of speech, say, one or a few words. Our approach is to perform a speaker-dependent warping of the frequency scale by selecting a Bark o set for each speaker. We choose the o set for a speaker to be the one that maximizes our(More)
This paper describes a study conducted to determine the feasibility of using a spoken questionnaire to collect information for the Year 2000 Census in the USA. To reene the dialogue and to train recognizers, we collected complete protocols from over 4000 callers. For the responses labeled (about half), over 99 percent of the answers contain the desired(More)
This paper reports the results of the development, deployment and testing of a large spoken-language dialogue application for use by the general public. We built an automated spoken questionnaire for the U.S. Bureau of the Census. In the project's rst phase, the basic recognizers and dialogue system were developed using 4,000 calls. In the second phase, the(More)
This paper describes eight telephone-speech corpora at various stages of development at the Center for Spoken Language Understanding. For each corpus, we describe data collection procedures, methods of soliciting callers, protocol used to collect the data, transcriptions that accompany the speech data, and the expected release date. The corpora are(More)
The miniaturization of integrated fluidic processors affords extensive benefits for chemical and biological fields, yet traditional, monolithic methods of microfabrication present numerous obstacles for the scaling of fluidic operators. Recently, researchers have investigated the use of additive manufacturing or "three-dimensional (3D) printing"(More)
Waterborne intruder detection includes many new challenges not seen in land environments. One area of these challenges is the detection of surface swimmers. Swimmers, whose bodies are partially in air and partially submerged, have significantly reduced target strength (TS) for radar and sonar systems compared to intruders fully in air or fully submerged.(More)
In this paper, we describe a rapid-prototyping approach to developing spoken language systems (SLSs). This new design methodology facilitates more usable and quickly implemented SLSs. Moreover, it allows SLS developers to address the delicate balance between designing dialogues that are sufficiently constraining to meet current speech recognition(More)
