Each individual experineces intuition in a different way. Some may hear voices, but there are many other ways to experience intuition also.
Some people hear sound.
Others see colors. Some people get sensations that they are able to recognize after a while. Some people get physical experiences. There are no correct way to experience intuition. Your intuitional structure, the way you experience intuition is as unique as your body.
