Why can't people talk underwater?

In order for someone underwater to hear you, the sound waves have to go from the air in your mouth into the water surrounding you. Sound waves have a hard time going from air into water and mostly get reflected at the air-water interface instead of being transmitted into the water.

Can you talk while wearing scuba gear?
