Personal style handwriting synthesis aims to produce texts in the writer?s style from a few handwriting samples. A handwriting synthesis system usually focuses on the production of the glyph, a handwriting unit separated by a space such as English word, Tamil word, Chinese character, Korean character, etc. However, glyph cannot be considered as the unit of direct generation, because the number of glyphs in a language is large and the handwriting shape varies over time, Since, the glyph consists of one or more of components, called graphemes, and a grapheme is an atomic unit of glyph that has a relatively unique shape, grapheme is a most desirable unit of handwriting generation. However, handwritten grapheme generation is not simple as it sounds, because a grapheme is written differently depending on its neighboring graphemes, which is called co-articulation effect.
