A user interface (102) of a portable electronic device (100) includes a plurality of keys (112). The user interface (102) includes a first group of keys representing vowel characters (402), and a second group of keys representing consonant characters (202). The second group of keys is separate from the first group of keys. For the first group of keys, a first key represents leading vowels (422, 424, 426), a second key represents above and below vowels (428, 430), and a third key represents following vowels (432, 434, 436). The second group of keys may be subdivided into phonetic consonant groups (FIGS. 5 & 6) or alphabetic consonant groups (FIGS. 7 & 8).
