Dragon shouts can not replace regular spells, because they are unique and powerful, but rare and hard to find and develop.
For each shout you have to find and learn three "word of power" to maximize and those words are guarded by all sorts of traps and monsters, and for each word of power that you have learned, you have to actually kill "a dragon" to be able to use.
So it is not easy to cast dragon shouts, and would be only a viable choice in the later stages of the game.
On the other hand the dragon shouts mostly have unique and powerful effects that can not be replaced with spells and also can not replace regular spells, so with a shout you might slow down the time, but can not absorb the stamina out of your foe, and you might throw anything on the screen backwards and stun the opponents, but can not make the undead run away from you, and so on...
Each method has it's own usage.
