Mainland Chinese Braille

Mainland Chinese Braille is a braille script for Standard Chinese used in China.^[1] Consonants and basic finals conform to international braille, but additional finals form a semi-syllabary, as in bopomofo. Each syllable is written with up to three Braille cells, representing the initial, final, and tone, respectively. In practice tone is generally omitted as it is in pinyin.

Traditional Chinese Braille is as follows:^[2][3]

Chinese Braille initials generally follow the pinyin assignments of international braille. However, j, q, x are replaced with g, k, h, as the difference is predictable from the final. (This reflects the historical change of g, k, h (and also z, c, s) to j, q, x before i and ü.) The digraphs ch, sh, zh are assigned to ⠟ (its pronunciation in Russian Braille), ⠱ (a common pronunciation in international braille), and ⠌. R is assigned to ⠚, reflecting the old Wade-Giles transcription of ⟨j⟩. (⠗ is used for the final er, the pronunciation of the name of that letter in English Braille.)

The finals approximate international braille values for several of the basic vowels (⠢ e (o), ⠊ yi, ⠕ wo, ⠥ wu, ⠬ yü, ⠳ you, ⠮ ei), but then necessarily diverge. However, there are a few parallels with other braille alphabets: ⠗ er and ⠽ wai are pronounced like the names of those letters in English braille; ⠑ ye, ⠫ ya, and ⠳ you are pronounced like those letters in Russian Braille. ⠯ yuan, ⠾ yue, ⠣ yin, are similar to the old French pronunciations oin, ieu, in. For the most part, however, Chinese Braille finals do not obviously derive from previous conventions.

The pinyin final -i is only written where it corresponds to yi. Otherwise* (in ci zi si ri chi zhi shi) no final is written, a convention also found in bopomofo. The final -e is not written in ⠙ de, a common grammatical particle written with several different characters in print.^[4]

Pinyin Bopomofo Braille a ㄚ e/o ㄛ ㄜ ㄝ ai ㄞ ei ㄟ ao ㄠ ou ㄡ an ㄢ en ㄣ ang ㄤ eng ㄥ

Pinyin Bopomofo Braille yi, -i* ㄧ ya, -ia ㄧㄚ ye, -ie ㄧㄝ yao, -iao ㄧㄠ you, -iu ㄧㄡ yan, -ian ㄧㄢ yang, -iang ㄧㄤ yin, -in ㄧㄣ ying, -ing ㄧㄥ

Pinyin Bopomofo Braille wu, -u ㄨ wa, -ua ㄨㄚ wo, -uo ㄨㄛ wai, -uai ㄨㄞ wei, -ui ㄨㄟ wan, -uan ㄨㄢ wen, -un ㄨㄣ wang, -uang ㄨㄤ weng, -ong ㄨㄥ

Pinyin Bopomofo Braille yu, -ü ㄩ yue, -üe ㄩㄝ yuan, -üan ㄩㄢ yun, -ün ㄩㄣ yong, -iong ㄩㄥ er ㄦ

Tone is marked sparingly.

Chinese Braille punctuation approximates the form of international braille punctuation, but several spread the corresponding dots across two cells rather than one. For example, the period is ⠐⠆, which is the same pattern as the international single-cell norm of ⠲.

A braille cell ⠼ called number sign (simplified Chinese: 数号; traditional Chinese: 數號; pinyin: shùhào) is needed when representing numbers.

Examples:

⠼⠚ 0, ⠼⠁ 1, ⠼⠃ 2, … ⠼⠊ 9,

⠼⠁⠚ 10, ⠼⠁⠁ 11, ⠼⠁⠃ 12, … ⠼⠁⠊ 19, … ⠼⠃⠊ 29, … ⠼⠊⠊ 99,

⠼⠁⠚⠚ 100, ⠼⠃⠑⠋ 256, ⠼⠁⠚⠃⠙ 1024, ⠼⠁⠚⠙⠓⠑⠛⠋ 1048576.

• Spaces are added between words, rather than between syllables.
• Tone is marked when needed. It comes after the final.
• As in bopomofo, the finals of the syllables zi, ci, si, zhi, chi, shi, ri are not marked.

Two examples, the first with full tone marking, the second with tone for disambiguation only:

Chinese Braille has the same low level of ambiguity that pinyin does. In practice, tone is omitted 95% of the time, which leads to a space saving of a third. Tone is also omitted in pinyin military telegraphy, and causes little confusion in context.

The initial pairs g/j, k/q, h/x are distinguished by the final: initials j, q, x are followed by the vowels i or ü, while the initials g, k, h are followed by other vowels. This reflects the historical derivation of j, q, x from g, k, h before i and ü,^[5] and parallels the dual pronunciations of c and g in Spanish and Italian. In pinyin, the redundancy is resolved in the other direction, with the diaeresis omitted from ü after j, q, x. Thus braille ⟨gü⟩ is equivalent to pinyin ju:

⠛⠥ gu,

⠛⠬ ju.
