Voice command recognition for fighter pilots using grammar tree

Abstract

This research copes with the voice command recognizer for fighter pilots. The voice command is composed of several connected words in the fighter system. And the recognizer automatically separates the command into individual words and implements isolated word recognition for each word. To improve the performance of the command recognizer, the error correction using grammar tree is proposed. The isolated word recognition error is corrected in the error correction process. Our experimental result shows that the grammar tree significantly improved the performance of the command recognizer. © 2012 Springer-Verlag.
