Bharati braille (/ˈbɑːrəti/BAR-ə-tee), orBharatiya Braille (Hindi:भारती ब्रेलbhāratī brēlIPA:[bʱaːɾət̪iːbɾɛːl] "Indian braille"), is a largely unifiedbraille script for writing thelanguages of India. When India gained independence, eleven braille scripts were in use, in different parts of the country and for different languages. By 1951, a single national standard had been settled on, Bharati braille, which has since been adopted bySri Lanka,[1]Nepal, andBangladesh.[2] There are slight differences in the orthographies for Nepali in India and Nepal, and for Tamil in India and Sri Lanka. There are significant differences inBengali Braille between India and Bangladesh, with several letters differing. Pakistan has not adopted Bharati braille, so theUrdu Braille of Pakistan is an entirely different alphabet than the Urdu Braille of India, with their commonalities largely due to their common inheritance from English orInternational Braille.Sinhala Braille largely conforms to other Bharati, but differs significantly toward the end of the alphabet.

Bharati braille alphabets use a 6-dot cell with values based largely onEnglish Braille. Letters are assigned as consistently as possible across the various regional scripts of India as they are transliterated in the Latin script, so that, for example, Hindi, Urdu, Bengali, and English are rendered largely the same in braille.

System

[edit]

Although basically alphabetic, Bharati braille retains one aspect of Indianabugidas, in that the default vowela is not written unless it occurs at the beginning of a syllable or before a vowel. This has been called a "linearized alphasyllabary abugida".[3] For example, and takingDevanagari as a representative printed script, the braille letter (the consonantK) renders printka, and braille (TH) renders printtha. To indicate that a consonant occurs without a following vowel (as when followed by another consonant, or at the end of a syllable), avirama (vowel-canceling) prefix is used: (virama-K) isk, and (virama-TH) isth. However, unlike in print, there are no vowel diacritics in Bharati braille; vowels are written as full letters following the consonant, regardless of their order in print. For example, in print the voweli is prefixed to a consonant in a reduced diacritic form,किki, but in braille it follows the consonant in its full form: (K-I), equivalent to writingकइ forki in print. Thus printक्लिकklika is written in braille as (virama-K-L-I-K). The one time a non-initial shorta is written in braille is when it is followed by another vowel. In this environment thea must be written, because otherwise the subsequent vowel will be read as following the consonant immediately. Thus printकइkai is rendered in braille as (K–A–I), to disambiguate it from forकिki.

Apart from thekṣ and, Bharati braille does not handleconjuncts. Consonant clusters written as conjuncts in print are handled with the virama in braille, just as they are with computer fonts that lack the conjuncts. Bharati braille is thus equivalent to Grade-1 English braille, though there are plans to extend all the Bharati alphabets to include conjuncts.

Punctuation

[edit]

Some of the punctuation marks (comma, close quote) duplicate letters. The caps mark is only used when transcribing English.

The 'accent',, transcribes Urdu ّshaddah (tashdeed), and the colon,, is also used for Urdu ةta marbuta.[citation needed]

In Bangladesh and Nepal, several additional punctuation marks are noted, but they do not agree with each other. It is not clear which are used in India. (SeeBengali Braille andNepali Braille.)

Pointing and Urdu

[edit]
Main articles:Urdu Braille andHindi Braille

The pointing symbol,, is used for consonant letters that in print are derived by adding a dot to another consonant. For Urdu, the base letter in Devanagari is used: the pointing of the Arabic/Persian script is not reflected. For example, Gurmukhiਗ਼ / Urdu غ / Devanagariग़ġa[ɣ], formed by adding a dot tog in Gurmukhi and Devanagari, is writtenpoint-G in all three. With Urdu, this is only done in India.

Other languages

[edit]

Ethnologue 17 reports braille usage forMizo,Garo, andMeitei. It is not clear if these are obsolete alphabets, or if they have been unified with Bharati Braille.

Digits

[edit]

Digits follow international conventions and are marked by.
