The measurement of the space-time structure variations induced by strong cosmic events (supernovae, coalescing binaries of neutron stars, etc.) requires an oscillator with a relative stability of 10-21 on time scales typically ap100 ms. We demonstrate that the Virgo interferometer with a wavelength of 1.064 degm has a laser frequency with an in-loop stability of 1.0 times 10-21 on a 100 ms time scale,...
Confidence measures play a key role in spoken term detection (STD) tasks. The confidence measure expresses the posterior probability of the search term appearing in the detection period, given the speech. Traditional approaches are based on the acoustic and language model scores for candidate detections found using automatic speech recognition, with Bayes' rule being used to compute the desired posterior...
As part of the general growth and diversification of media in different modalities, the presence of information in the form of human speech in the world-wide body of digital content is becoming increasingly significant, in terms of both volume and value. We present a semantic- based search model for human speech corpora, stressing the search for meanings rather than words. Our framework embraces the...
This paper deals with the problem of speech recognition on band-limited speech. In our previous work we showed how a simple polynomial correction framework could be used for compensation of band-limited speech to minimize the mismatch using full-bandwidth acoustic models. This paper extends this approach to time-varying multiple-channel environments. The compensation framework is extended to perform...
This paper describes a software platform used for controlling any set of collaborative robots. The platform is specially designed for users without special skills on hardware design or communication topics. The platform provides a standard to simplify the addition of new hardware devices. The system runs over Linux operating system; it is accessible through different programming languages. Calls among...
