Definitions for "Predictive text input"
When typing text messages, you may have to press numbers 3 or 4 times to select a letter. With PTI, you press the relevant number just once and the handset guesses which letter you want to select.
For typing messages, Predictive Text Input, also known as T9 Text Input, is twice as fast as multi-tapping, and it is the easiest way to type text using the limited keypad on a mobile phone.• Just one key press per letter with no multi-tapping• Extensive word database including proper names• Ability to add words to the T9 Text Input database• Available in many languages• Full punctuation and symbol capabilities By using the letters grouped on each phone key and a 'fast access' database, T9 software requires just one key press per letter to quickly recognize the most commonly used word for a specific key sequence. For example, you can enter the word 'how' with only three keys: 4-6-9. You'd have to use twice as many keys using multi-tap. T9 knows that the most commonly used word with that key sequence in 'how'. If more than one word has the same sequence, T9 displays the most commonly used word first. If that's not the word you want, you can view the next word matching that key sequence by pressing the NEXT key (usually the down arrow or 0 key, but check your manufacturers user guide for your phone).
Predictive Text Input is a technology which allows one to enter text by pressing only one key per letter. T9 is a Pedictive text input.
