This condition is known as “helium ear.” The diver must often be reminded to enunciate his words when he speaks through the intercom to the supervisors and life support technicians who monitor him from outside the complex. Saturation systems often come equipped with a Helium Speech Unscrambler, a device that slows down the speed of the divers’ voices. One company that manufactures these devices boasts of their ability to correct a diver’s “raw helium speech to normal intelligible voice levels.”
