The idea is that you have to know the Shouts (as in correct words and pronunciations) to utilize them; I highly doubt the Average Joe who stumbled across the Helmet would know the actual words to may Shouts outside of Unrelenting Force and maybe Whirlwind Sprint. Also, there is no "built-in" cooldown so a person could conceivably utter multiple shouts in rapid succession; however, uttering too many Shouts in rapid succession without any respite will greatly strain ones respiratory system. The intensity of the Shout (in other words the number of words uttered) directly affects the amount strain experienced by such rapid-fire yelling: a person could utter a score of one-word Whirlwind Sprints in rapid succession before feeling any discomfort (though only moving a few yards at a time) while the same person uttering 4 or five three-word Unrelenting Forces in rapid succession would threaten shredding their vocal chords.

Of course, even if they person should destroy their speaking capabilities, they would still be left with increased physical capacity, resistance to extreme cold, and great fighting prowess.
