Abstract

The described systems and methods relate to a user friendly, efficient and easy to use keyboard and/or keypad device for entering characters of a script, wherein the characters, diacritic marks, and extended sets thereof are assigned to one or more phonetically similar English alphabet character keys of existing keyboards/keypads. In an embodiment, to access assigned phonetically similar characters of a script or diacritic marks or extended sets thereof through the existing keyboard and/or keypad device, the desired and corresponding English alphabet character key is multi-tapped to sequentially generate and display all assigned phonetically similar characters of a linguistic script, which can be then selected based on desired text to be input.
