Development of a Spoken Language System
Abstract
The goal of this research project is to integrate speech and natural language technologies into a spoken language system capable of understanding and responding to spoken English for interactive human-machine military applications, such as command and control, training of military personnel, and logistics planning. The system we are building, called HARC (Hear And Respond to Continuous speech) will include a capability to adapt to new speakers and a capability to detect when a user says a new word. Major accomplishments this year include: 1) top performance in the first multi-site competitive evaluation; 2) speedup of the natural language processing component (Delphi); 3) rapid port to the ATIS domain; 4) extending the discourse mechanism, including the handling of more general forms of definite reference; 5) selection of the TRANSCOM domain for our demonstration SLS system; 6) integration of speech recognition and natural language processing; 7) detecting and adding new vocabulary words in speech; 8) several new more efficient search algorithms for speech processing; and 9) demonstration of real-time speech recognition with N-Best sentence output.
