Abstract : The purpose of this effort was to develop and demonstrate the capability of automatic flight plan filing by machine recognition. In 1979, the Technical Center undertook an extensive effort to upgrade the Utterance Recognition Device (URD) in preparation for testing the capabilities of voice input for automatic flight plan filing. The URD was modified to include more reliable components, where advisable, and a larger memory to handle the expanded vocabulary. In addition, a dialect study was conducted to determine the locations for collecting a nationally representative voice sample in order to create reference patterns capable of performing well on all American dialects. Subsequently, over 5,000 voices from 24 cities throughout the United States were collected and processed.
