Correct Answer : Direct voice input
Explanation : DVI control is direct voice input control through which the pilot can enter flight and navigational commands through voice.
Correct Answer : Option (B) : False
Explanation : The DVI control system is a universal system which can recognize the voice of anyone if spoken clearly. This is done for maintenance purposes and for an emergency.
Explanation : The DVI control system must be super sensitive to the voice of the pilot so that it can be operated in cockpit noise environment. In a fast jet combat aircraft, the background noise levels can be very high.
Correct Answer : Option (C) : Systems that require a pause between each word to recognize
Explanation : An isolated word recognizer requires pauses between each word said as it cannot recognize fully connected speech. The DVI control in an aircraft must not be an isolated voice recognizer to ensure smooth man-machine interface.
