Spoken Word Display Technology

A Japanese firm has developed a technology to enable users to display their spoken words on a tablet or a smartphone by dragging their finger on the screen.
Mitsubishi Electric has combined touch-technology and voice recognition to develop an application that helps to overcome hearing disabilities and linguistic barriers.
To use this technology, which is supported on Android platforms, one needs to press down on the screen for a while before running a finger along the surface while speaking.
When the screen is pressed twice, the system analyses the written text, and can even read it aloud or translate it in 10 different languages.
