In previous work we showed that state-of-the-art end-of-utterance detection (as used, for example, in dialog systems) can be improved significantly by making use of prosodic and/or language models that predict utterance endpoints, based on word and alignment output from a speech recognizer. However, using a recognizer in endpointing might not be practical in certain applications. We demonstrate that the improvements due to the prosodic knowledge can be realized largely without alignment information, i.e., without requiring a speech recognizer. A prosodic end-of-utterance detector using only speech/nonspeech detection output is still considerably more accurate and has lower latency than a baseline system based on pause-length thresholding.

We explore how techniques that were developed to improve the training process of artificial neural networks can be used to speed up fuzzy clustering. The basic idea of our approach is to regard the difference between two consecutive steps of the alternating optimization scheme of fuzzy clustering as providing a gradient, which may be modified in the same way as the gradient of neural network back-propagation is modified in order to improve training. Our experimental results show that some methods actually lead to a considerable acceleration of the clustering process.

With the continuing development of mobile telecommunications,a mobile phone usually contains multiple functions and features,such as e-mail sending capabilities,text messaging,notebooks, electronic dictionaries,and so *** paper is concerned with the placement of Chinese phonetic symbols for an intellectual Chinese phonetic symbol input system in mobile phones.A good placement of Chinese phonetic symbols can efficiently reduce the typing time when Chinese characters are entered. Applying the genetic algorithm,we can easily find the appropriate placement of phonetic symbols on the keypads of mobile *** the experimental results show,our method is not only substantially better than the traditional Chinese phonetic symbol input system but is also better than the general placement of phonetic symbols used in an intellectual Chinese phonetic symbol input system.

A predictive vector quantization (Gray, M., 1984; Jain, A.K. et al., 2000) based speaker and text independent language identification system is proposed, which uses the statistical distribution of predictive error vectors to recognize the language spoken by native speakers. According to Stan C. Kwasny et al. (see Proc. 5th Midwest Artificial Intelligence and Cognitive Science Soc. Conf., p.53-7, 1993), most high level features of speech, such as tone of voice, rhythm, style, pace, accent, etc., appear to be related to distributional patterns or statistical aggregates of speech waveforms. We further develop the method used by Qian-Rong Gu and Tadashi Shibata (6th World Multiconference on Systemics, Cybernetics and Informatics - SCI2002, 2002) to extract these statistical distributional patterns directly from raw speech waveforms and then use them to identify language. The system has been trained and. tested by speech from English and Japanese native speakers. A best identification ratio of 76.8% can be achieved by our system.

In the near future, it will be necessary for the senior citizens to nurse the other senior citizens because of declining population of children and increasing a new type of family. We have been developing welfare robots which can support lives of the senior citizens and have sensibility to lighten the burden imposed on nursing. The measurement of emotions from the usual conversation is considered to be one of its basic researches. In this paper, we are going to propose the algorithm of the emotion measurement and the prototype system based on this algorithm, and we are also going to discuss its validity.

We are investigating computational models for human-computer interaction based on a uniform, declarative, knowledge representation. We describe a new implementation of our work called Equuleus, a system for interactive, adaptive, document presentation. Equuleus achieves this by using annotated descriptions of a document to be presented and a planner to plan the document's presentation. All presentation occurs as a result of planning and re-planning presentation goals.

This paper presents the research and design of a KQML(knowledge query and manipulation language) speaking and CORBA-based intelligent multi-agent system (MAS). The MAS uses KQML as the agent communication language (ACL) and uses the CORBA event service and CORBA object trading service to implement the communication and facilitation mechanisms of the MAS. The functionality of the intelligent MAS is demonstrated with the UCAV (uninhabited combat aerial vehicle) operator control sharing application.
