Cantonese Braille is a braille script used to write Cantonese in Hong Kong and Macau. It is locally referred to as tim chi (點字, dim2zi6) 'dot characters' or more commonly but ambiguously tuk chi (凸字, dat6zi6) 'raised characters'. Although Cantonese is written in Chinese characters, Cantonese Braille is purely phonetic, with punctuation, digits and Latin letters from the original Braille. It can be mixed with English text.
Each syllable is divided into three parts: the initial consonant, the rime (vowel and any final consonant), and the tone. For example, 盤, pun4 is written, with initial p, final un and tone 4.[1] (See Cantonese phonology.) Among initials, aspirated consonants (p t ts k kw = p' t' ts' k' kw) are derived by adding dots to the unaspirated consonants (b d dz g gw = p t ts k kw):

The rimes eu, em, ep do not exist in braille.
High tone (tones 1 and 7) is not transcribed. Otherwise tone is written after the rime, as follows:

Some of the punctuation marks are distinguished from the onset or rime of a syllable by the strategic use of the space. The spaces are therefore included in the table below, though they are not technically part of the punctuation mark.
