In this paper, we describe a new methodology to develop mixed-initiative spoken dialog systems, which is based on the extensive use of simulations to accelerate the development process. With the help of simulations, a system providing information about a database of nearly 1000 restaurants in the Boston area has been developed. The simulator can produce(More)
Experimental prolonged febrile seizures (FS) lead to structural and molecular changes that promote hippocampal hyperexcitability and reduce seizure threshold to further convulsants. However, whether these seizures provoke later-onset epilepsy, as has been suspected in humans, has remained unclear. Previously, intermittent EEGs with behavioural observations(More)
Through efforts over the past fifteen years, we have acquired a great deal of experience in designing spoken dialogue systems that provide access to large corpora of data in a variety of different knowledge domains, such as flights, hotels, restaurants, weather, etc. In our recent research, we have begun to shift our focus towards developing tools that(More)
This paper describes a novel multi-stage recognition procedure for deducing the spelling and pronunciation of an open set of names. The overall goal is the automatic acquisition of unknown words in a human computer conversational system. The names are spoken and spelled in a single utterance, achieving a concise and natural dialogue flow. The first(More)
We have designed, implemented and evaluated an end-to-end system spellchecking and autocorrection system that does not require any manually annotated training data. The World Wide Web is used as a large noisy corpus from which we infer knowledge about misspellings and word usage. This is used to build an error model and an n-gram language model. A small(More)
Human cancers and some congenital traits are characterized by cytogenetic aberrations including translocations, amplifications, duplications or deletions that can involve gain or loss of genetic material. We have developed a simple method to precisely delineate such regions with known or cryptic genomic alterations. Molecular copy-number counting (MCC) uses(More)
Mixed-initiative spoken dialogue systems today generally allow users to query with a fixed vocabulary and grammar that is determined prior to run-time. This paper presents a spoken dialogue interface enhanced with a dynamic vocabulary capability. One or more word classes can be made dynamic in the speech recognizer and natural language (NL) grammar so that(More)
SPEECH RECOGNITION USING THE ANGIE FRAMEWORK1 Grace Chung and Stephanie Sene Spoken Language Systems Group Laboratory for Computer Science Massachusetts Institute of Technology Cambridge, Massachusetts 02139 USA http://www.sls.lcs.mit.edu, mailto:fgraceyc, sene g@mit.edu ABSTRACT We describe a novel hierarchical duration model for speech recognition.

This paper concerns the handling of out-of-vocabulary (OOV) words in the JUPITER weather information system. Specifically our objective is to deal with weather queries regarding unknown cities. We have implemented a system which can detect the presence of an unknown city name, and immediately propose a plausible spelling for that city. Potentially, the city(More)
