There are two general types of speech recognizers available for use with children; speaker-independent systems with a limited vocabulary designed for use with computer games, and speaker-dependent devices with larger vocabularies that must be "trained" by users. neither is adequate for educational… More

One of the biggest barriers to effective and wide spread use of computers by non-computer-specialists is the need for users to interact with computers in "computerese" rather than english. additionally, the lack of standard software modules that "understand" natural language hampers the development… More

The purpose ofthis research effort is to determine the feasibility of using bilingual text analysis software as a tool to assist in teaching english writing skills to non -native speakers. since spanish is the vative language predominantly spoken by students enrolled in bilingual prl programs in… More

Speech recognition in air traffic control (atc) (noise, multiple voices) and psychological or physical stress (peak traffic periods, colds), while meeting the need of error-resistant operation. a successful design that "captures" the information already communicated verbally, however, would save… More

Although members of the linguistic and speech recognition communities recognize the importance of suprasementals (duration, intensity, and fundamental frequency or pitch) inunderstanding the speech code, there is relatively little quantifiable data available, particularly on pitch. emerson & stern… More

The members of the deaf community in the united states are isolated from both the hearing population and each other. a primary cause of this isolation is the absence of a commonly accepted written form of american sign language (asl). a recently devised symbol set, called sign writing (r), has been… More

Each year there are 70,000 new head trauma victims whose primary medical and long-term rehabilitation costs place tremendous financial burdens on their families. the need is great for low-cost rehabilitation tools that can be used in the home to supplement and phase i of this effort will explore the… More

Students in english as a second language programs come from diverse language backgrounds, with spanish and combined asian languages representing over 90% of those backgrounds. writing, the most daunting aspect of learning another language, is a skill that demands individualized instructionand… More

The long-tern goal of phase i and phase ii research is to provide a new tool for speech therapy based on the display of vocal tract cross-sections. the signal processing approaches under investigation are based on speech recognition techniques. this system would permit users to see in a concrete,… More

The long-term goal of phase i and phase ii research is to provide an innovative technology for synthesizing sign language based on the translation of the written form of a sign into abstract formational components -- handshapes, locations, movements -- and the compilation of graphic animations from… More

The overall goal of this effort is to develop an effective software tool for remediating the types of writing problems specific to the learning disabled population. the phase i research will focus on the modification of write and proof, a word processing program with the capability of checking… More

This effort is intended to demonstrate the feasibility of designing a voice i/o (input/output) system suitable for application in the cockpit of a commercial aircraft for the purpose of facilitating interaction with a sophisticated flight management system. the ultimate system needs to incorporate… More

The overall goal of this effort is to develop an effective software tool for addressing the types of writing problems specific to the deaf population. the phase i research will focus on the modification of write this way, a word processing program with the capability of checking spelling and grammar… More

The purpose of this research effort is to develop a prototype tactical speech recognizer by modifying and extending emerson & stern's current technologies for speaker-independent (i.e. no training), continuous speech recognition, including its existing stress resistance, noise-tracking and… More

After many years of research, speech recognition is becoming practical. emerson & stern recently introduced soliloquy (stabilizer) voice interface software, which meetsmany of the market's demands for speaker-independent, natural language, continuous speech input. since soliloquy's unique approach… More

The goal of this application is an interactive, computer-mediated, telephone monitoring system that uses automatic speech recognition (asr) to improve blood pressure controlling hypertensive patients by improving physician monitoring and patient compliance with antihypertensive drug regimens. the… More

The long-term objective of this research in phase i and phase ii is to develop a speaker-independent, voice-activated telephone interface for use by quadriplegics and others, with the innovative capability of handling speech produced by people who require ventilators. specific objectives include:… More
