Question

What are isolated word recognizers?

(a) Systems that can recognize anyone’s voice

(b) System that is not fully voice commanded

(c) Systems that require a pause between each word to recognize

(d) Systems that only accept one-word command

I have been asked this question in my homework.

This is a very interesting question from Control and Data Entry in section Displays and Man-Machine Interaction of Avionics

Answer 1

Right answer is (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.
