The Multi-tap code is the name given to the telephone input technique that consists of writing a letter by repeating the corresponding key on the mobile phone keypad. For example: '2' for 'A', '22' for 'B', '222' for 'C', '3' for D, and so on 'CODE' is written '222-666-3-33'. dCode has a tool for that:
T9 code is the name given to the prediction algorithm that uses a dictionary to guess the word the user is trying to write. For example: '2' for 'A' or 'B' or 'C', '222' for 'BAC' or 'ABC'. 'CODE' is written '2633'. dCode has a tool for that:
T9 has short numbers, whose length is equal to the letter number in the word. There is little repetition of the same digit. This is the fastest way to type SMS without abbreviations.
The ABC multitap has long numbers (much longer than the original word), with many repetitions of consecutive digits (successive presses on the same key). This is the quickest way to type text messages with abbreviations.
