A handwriting compound system is provided. The system includes a handwriting recognition module that receives a proper number of letters from a user, detects a distance between phonemes/syllables, and shapes and locations of the phonemes/syllables, and recognizes the user's handwriting. The system also includes a point designating module, a reference point setting module and a handwriting transforming module. The point designating module designates a particular one of the subdivided positions in each phoneme recognized by the handwriting recognition module. The reference point setting module sets a reference point, serving as reference for the alteration of a phoneme/syllable, inside or outside the user's input phoneme/syllable recognized by the handwriting recognition module. The handwriting transforming module designates x and y coordinates of a first point with respect to the reference point. The handwriting transforming module sets x and y coordinates of the next points following the first point, based on the distances between a previous and the next point in the x- and y-axes, to determine a relative coordinate of each point. The handwriting transforming module alters a relative coordinate of a particular phoneme/syllable or a particular point. The handwriting transforming module transforms the position, distance, and shape of handwriting.
