TL;DR: In this project, a phonetically-based spoken language understanding system called SUMMIT is developed, which attempts to express the speech knowledge within a formal framework using well-defined mathematical tools.
Abstract: Recently, we initiated a project to develop a phonetically-based spoken language understanding system called SUMMIT. In contrast to many of the past efforts that make use of heuristic rules whose development requires intense knowledge engineering, our approach attempts to express the speech knowledge within a formal framework using well-defined mathematical tools. In our system, features and decision strategies are discovered and trained automatically, using a large body of speech data. This paper describes the system, and documents its current performance.

TL;DR: This paper documents the data collection process, and provides some preliminary analyses of the collected speech data, composed of spontaneous sentences which were collected during a simulated human/machine dialogue.
Abstract: As part of our effort in developing a spoken language system for interactive problem solving, we recently collected a sizeable amount of speech data. This database is composed of spontaneous sentences which were collected during a simulated human/machine dialogue. Since a computer log of the spoken dialogue was maintained, we were able to ask the subjects to provide read versions of the sentences as well. This paper documents the data collection process, and provides some preliminary analyses of the collected data.

TL;DR: Early experience with the development of the MIT VOYAGER spoken language system is described, which addresses applications in which speech is used for interactive problem solving between a person and a computer.
Abstract: As part of the DARPA Spoken Language System program, we recently initiated an effort in spoken language understanding. A spoken language system addresses applications in which speech is used for interactive problem solving between a person and a computer. In these applications, not only must the system convert the speech signal into text, it must also understand the linguistic structure of a sentence in order to generate the correct response. This paper describes our early experience with the development of the MIT VOYAGER spoken language system.

TL;DR: The preliminary evaluation of VOYAGER is described, using a spontaneous speech database that was recently collected, that provides information and navigational assistance for a geographical area within the city of Cambridge, Massachusetts.
Abstract: VOYAGER is a speech understanding system currently under development at MIT It provides information and navigational assistance for a geographical area within the city of Cambridge, Massachusetts Recently, we have completed the initial implementation of the system This paper describes the preliminary evaluation of VOYAGER, using a spontaneous speech database that was also recently collected
