Intelligence Report Voice Input.

Abstract

This work was an initial effort in the use of voice data entry for information data handling. The objective of this effort was to develop the technology for a large vocabulary (1000 word) isolated word recognition system capable of quick adaptation and high accuracy for a limited number of people. Techniques for word boundary detection, noise suppression, and frequency sealing were examined. Tests were conducted on a 1000 word and a 100 word unstructured vocabulary. Recognition accuracies of 30.5% and 66% were obtained for the untrained case and 62.4% and 90% after training each word once. (Author)
