Moallem is of the opinion that such handheld devices may make it easier for deaf people to follow conversations than with lip reading alone, which requires a great deal of concentration.
"It's hard to have a casual conversation in a situation where you have to be paying attention like that," he says.
Current prototypes can be held in the user's hand or worn around the back of the neck, but once the acoustic processing software is developed, it could be easily incorporated into existing smart phones, according to the researchers.
With an eye on realising such applications, the research team are investigating the best way to transform sound waves into vibrations.
The MIT researchers hope to improve existing tactile aids, which have been in use for decades, by refining the acoustic signal processing systems to provide tactile cues that are tailored to boost lip-reading performance.
