Initials of the Chinese language are classified into nine initial groups. The first touch of a numeric key of a cellular phone selects an initial group including the initial of the desired syllable for input. Then, guidance is displayed corresponding to a final group to which the final of the desired syllable belongs. The syllable is determined based on the operation according to the guidance. The present invention classifies finals into the first final group composed of simple finals, the second final group composed of complex finals that start with a, e, or o, the third final group composed of complex finals that start with i, or y, the fourth final group composed of complex finals that start with u, or w, and the fifth final group composed of complex finals that start with v, or yu.
