AIRCRAFT VOICE COMMAND EXECUTION METHOD AND COCKPIT VOICE COMMAND RECOGNIZER SYSTEM THEREFOR

摘要

According to a fighter pilot voice command execution method of the present invention, a voice command (fighter command) of a pilot is automatically divided into the word unit and a silent syllable is hidden with the energy processing of a short section signal and zero crossing rage processing. A voice characteristic parameter is determined from a mel-frequency cepstrum coefficient (MFCC) and a recognizing candidate group by the word is set. The recognizing candidate group by the word is formed of a command of a connection word base with a connection word matching technique based on a verbal tree. Therefore, word matching times are reduced dramatically and a recognizing rate of the command is highly increased. Especially, a word recognizing time is reduced by reducing the similarity measuring times.
