Cantonese Braille

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):

Initials

• M and ng may also be used as rimes (syllabic nasals), in which case they are followed directly by the tone.
• When i or u (but not y) begins a syllable, a dummy consonant j or w is prefixed.

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:

Punctuation

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.

The emphasis marks, ⠷⠻ are equivalent to running dots alongside the characters in print, while proper names are marked in print by an underline or overline.
