~ there is only one control and that is typically given by voice
~ operator needs not be aware of helicopter's dynamics
~ in fact, voice control is not a major issue in project
~ operator speaks a command into a microphone and
~ digitized speech is then analyzed using a conventional speech processing box,
~ which decides if it is one of allowable commands and if so, displays its choice on a CRT
~ if operator agrees with analysis he confirms choice by pressing a key,
~ and command is then transmitted to helicopter
~ A second microphone near speaker functions as an active sound subtraction system; operation environment is quite noisy
