We have investigated the use of a pitch adaptive spectral representation on large vocabulary speech recognition, in conjunction with speaker normalisation techniques. We have compared the effect of a smoothed spectrogram to the pitch adaptive spectral analysis by decoupling these two components of STRAIGHT. Experiments performed on a large vocabulary meeting speech recognition task highlight th...

This paper presents a novel method for automatically generating English vocabulary tests using TOEFL vocabulary questions as a model. English vocabulary questions in TOEFL is a multiple-choice question consisting of four components: a target word, a reading passage, a correct answer and distractors. Given a target word, we generate a reading passage from Web texts retrieved from the Internet, a...

There are three key components for developing a metadata system: a container structure laying out the key semantic issues of interest and their relationships; an extensible controlled vocabulary providing possible content; and tools to create and manipulate that content. While metadata systems must allow users to enter their own information, the use of a controlled vocabulary both imposes consi...

Canonical abstract prototypes are an innovative means for specifying and exploring visual and interaction design ideas. Intermediate between abstract task models and realistic or representational prototypes, canonical abstract prototypes provide designers with a standardized vocabulary for expre ssing visual and interaction designs independent of details of appearance and behavior. This common ...

To individualize instruction, a tutor must infer which knowledge components the student knows and does not know. Self-assessments, by which the student directly reports to the tutor whether a certain item is known, are a fast measure of student knowledge. We investigate their use to initialize a learner model used to individualize instruction ESL vocabulary. Experimental results indicate that s...

Due to the enormous development of large vocabulary, speaker-independent continuous speech recognition systems, which occur essentially for the US English language, there is a large demand of this kind of systems for other languages. In this paper we present the work done in the development of a large vocabulary, speaker-independent continuous speech recognition hybrid system for the European P...

this study was designed to find which one of the three different presentations, i.e. input, input-output, and output-input, will be more effective in iranian efl learners' vocabulary acquisitions. to this end, first 54 out of 64 female students, aged from 19 to 23 years, with an average of 21, were selected out of starter-level efl learners at the university of tarbiat moalem in bandar abb...

In the Baby CareLink system, information prescription plays an important role in preparing parents of premature infants for the eventual discharge to home of their children. However, the prescription process requires scarce clinician time in order to dispense information, and can become cumbersome as content bases grow in size. We describe the development of an OWL-based knowledge mediator to f...

This study investigated the relationship between two components of reading ability (ie reading comprehension and reading vocabulary) and six dimensions of self-perception (ie perceived scholastic competence, perceived intellectual ability, perceived creativity, perceived job competence, perceived social acceptance, and perceived global self-worth) as factors impacting academic performance. The ...
