The method and apparatus uses validity rules (242) to rearrange the order of presentation of the multiple alphabet symbols associated with a single key on the keypad (210), automatically eliminates the presentation of invalid alphabet symbols, and allows the entry of additional information such as a tone markers. Additionally, the method and apparatus uses a dictionary (244) to convert phonetic syllables into Chinese characters.
