We consider the problem of planning in complex domains where actions are stochastic, non-instantaneous, may occur concurrently, and time is represented explicitly. Our approach is based on the situation calculus based language Golog. Instead of general search for a sequence of actions, as in classical planning, we consider the problem of computing a deterministic, sequential program (with stoch...

In this paper we show our latest developments of speech and language technology for two languages: Spanish and Galician. Special attention is devoted to the situation of this minority language: Galician, where the lack of resources puts in danger its inclusion in speech products.

While the influence of orthographic knowledge on lexical and postlexical speech processing tasks has been consistently observed, it is not the case in tasks that can be performed at the prelexical level. The present study re-examined the orthographic consistency effect in such a task, namely in shadowing. Comparing the situation where the acoustic signal was clearly presented to the situation w...

This paper describes ome further attempts to identify and measure those parameters in the speech signal that reflect the emotional state of a speaker. High-quality recordings were obtained of professional "method" actors reading the dialogue of a short scenario specifically written to contain various emotional situations. Excerpted portions of the recordings were subjected to both quantitative ...

− The paper treats the issue of embedding the traceable length metrology into technological process by performing precise dynamic measurements of line scale in its manufacture line. It addresses the error-related problems specific to line scale calibration in dynamic mode of operation that are caused primarily by dynamic loads. Introducing the dynamic regime of calibration leads to the dynamic ...

In this paper, we present a real-time implementation of the ideal binary-mask algorithm, which is a promising approach for enhancing speech intelligibility. Our implementation is hardware efficient, making it suitable for embedded biomedical devices such as hearing aids and cochlear implants. We tested our algorithm implementation on an FPGA platform, and produced results that verify that it ef...

This report discusses the use of situation knowledge as a means to enhance the recognition performance of commercially available automatic speech recognizers. A cognitive model of the ATC controller is proposed that continuously observes the present situation and generates a prediction of the sentences the controller is most likely to say. The prediction is made available to the speech recogniz...

In unit selection based concatenative speech systems, join cost, which measures how well two units can be joined together, is one of the main criteria for selecting appropriate units from the inventory. The ideal join cost will measure perceived discontinuity, based on easily measurable spectral properties of the units being joined, in order to ensure smooth and natural-sounding synthetic speec...

One problem of interest in child language study has been specifying what features of the speech situation determine what children will say. Several cognitively based approaches to child language development have proposed principles of 'informativeness' to explain the child's choice of word(s). These principles predict that the child will choose the 'most informative' element of a situation and ...

This study delved into the application of proper nouns as terms of address in Russian and Persian. In other words, it examined the rules governing the application of terms of address expressed as the names of individuals in different speech situations in both languages. The comparative study of the cultural features of languages spoken by Russians and Iranians called for the investigation of th...
