Continuously Automatic Speaker Adaptation.
Abstract
An exploratory development model was implemented and a gisting scenario was devised utilizing a 50-word vocabulary simulating an air traffic control environment. The gisting scenario is an on-line voice-controlled program for the creation, appending and editing of gisting files while an operator is monitoring an air traffic control channel by means of a headset. Recognition results were obtained on the 50-word vocabulary which included ten connected digits plus control words and descriptors simulating the air traffic control environment. The vocabularies were subdivided in the manner of their use in the gisting scenario with fewer than 24 vocabulary words active at any time. A voice-operated DISABLE/ENABLE facility was provided to prevent the entry of irrelevant conversation into the gisting algorithm. Although real-time recognition was not fully achieved, on-line performance was successfully demonstrated and high recognition accuracy obtained over the entire 50-word vocabulary. (Author)
