1. A display device for adjusting a recognition sensitivity of a speech recognition starting word, display device comprising:
a display;
a microphone;
a memory configured to store a default starting word recognition engine that recognizes a speech recognition starting word; and
a processor configured to:
determine a valid recognition threshold range of the default starting word recognition engine,
sequentially assign recognition thresholds within the valid recognition threshold range to a predetermined number of sensitivity levels, respectively,
display a sensitivity setting interface including the sensitivity levels through the display, and
set a default recognition threshold of the default starting word recognition engine to a recognition threshold corresponding to the selected sensitivity level selected by a user through the sensitivity setting interface,
wherein the processor is configured to obtain first recognition thresholds that equally divide the valid recognition threshold range by the predetermined number of sensitivity levels, sequentially assign the obtained first recognition thresholds to the sensitivity levels, respectively, and to assign the default recognition threshold to one of the sensitivity levels and when the default recognition threshold is not included in the first recognition thresholds, assign the default recognition threshold to a sensitivity level to which one of the first recognition thresholds closest to the default recognition threshold has been assigned among the sensitivity levels.
