Bharati Braille
Bharati braille ( ), or Bharatiya Braille ( hi, भारती ब्रेल ' "Indian braille"), is a largely unified braille script for writing the languages 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 by Sri Lanka, Nepal, and Bangladesh. 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 in Bengali Braille between India and Bangladesh, with several letters differing. Pakistan has not adopted Bharati braille, so the Urdu 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 or International Braille. Sinhala Braille largely conforms to other Bharati, but differs signif ...

Alphabet
An alphabet is a standardized set of basic written graphemes (called letters) that represent the phonemes of certain spoken languages. Not all writing systems represent language in this way; in a syllabary, each character represents a syllable, and logographic systems use characters to represent words, morphemes, or other semantic units. The first fully phonemic script, the Proto-Sinaitic script, later known as the Phoenician alphabet, is considered to be the first alphabet and is the ancestor of most modern alphabets, including Arabic, Cyrillic, Greek, Hebrew, Latin, and possibly Brahmic. It was created by Semitic-speaking workers and slaves in the Sinai Peninsula (as the Proto-Sinaitic script), by selecting a small number of hieroglyphs commonly seen in their Egyptian surroundings to describe the sounds, as opposed to the semantic values of the Canaanite languages. However, Peter T. Daniels distinguishes an abugida, a set of graphemes that represent consonantal base ...

Sri Lanka
Sri Lanka (, ; si, ශ්‍රී ලංකා, Śrī Laṅkā, translit-std=ISO (); ta, இலங்கை, Ilaṅkai, translit-std=ISO ()), formerly known as Ceylon and officially the Democratic Socialist Republic of Sri Lanka, is an island country in South Asia. It lies in the Indian Ocean, southwest of the Bay of Bengal, and southeast of the Arabian Sea; it is separated from the Indian subcontinent by the Gulf of Mannar and the Palk Strait. Sri Lanka shares a maritime border with India and Maldives. Sri Jayawardenepura Kotte is its legislative capital, and Colombo is its largest city and financial centre. Sri Lanka has a population of around 22 million (2020) and is a multinational state, home to diverse cultures, languages, and ethnicities. The Sinhalese are the majority of the nation's population. The Tamils, who are a large minority group, have also played an influential role in the island's history. Other long established groups include the Moors, the Burghers ...

Urdu Alphabet
The Urdu alphabet (), is the right-to-left alphabet used for Urdu. It is a modification of the Persian script, which is itself a derivative of the Arabic script. The Urdu alphabet has up to 39 or 40 distinct letters with no distinct letter cases and is typically written in the calligraphic Nastaʿlīq script, whereas Arabic is more commonly written in the Naskh style. Usually, bare transliterations of Urdu into the Latin alphabet (called Roman Urdu) omit many phonemic elements that have no equivalent in English or other languages commonly written in the Latin script. History The standard Urdu script is a modified version of the Perso-Arabic script and has its origins in 13th century Iran. It is closely related to the development of the Nastaliq style of Perso-Arabic script. Despite the invention of the Urdu typewriter in 1911, Urdu newspapers continued to publish prints of handwritten scripts by calligraphers known as ''katibs'' or '' khush-navees'' until the late 19 ...

Unified International Braille
The goal of braille uniformity is to unify the braille alphabets of the world as much as possible, so that literacy in one braille alphabet readily transfers to another. Unification was first achieved by a convention of the ''International Congress on Work for the Blind'' in 1878, where it was decided to replace the mutually incompatible national conventions of the time with the French values of the basic Latin alphabet, both for languages that use Latin-based alphabets and, through their Latin equivalents, for languages that use other scripts. However, the unification did not address letters beyond these 26, leaving French and German Braille partially incompatible and as braille spread to new languages with new needs, national conventions again became disparate. A second round of unification was undertaken under the auspices of UNESCO in 1951, setting the foundation for international braille usage today. Numerical order Braille arranged his characters in decades (groups of ten) ...

Gurmukhī Script
Gurmukhī ( pa, ਗੁਰਮੁਖੀ, , Shahmukhi: ) is an abugida developed from the Laṇḍā scripts, standardized and used by the second Sikh guru, Guru Angad (1504–1552). It is used by Punjabi Sikhs to write the language, commonly regarded as a Sikh script, Gurmukhi is used in Punjab, India as the official script of the Punjabi language. While Shahmukhi script is used in Punjab, Pakistan as the official script. The primary scripture of Sikhism, the Guru Granth Sahib, is written in Gurmukhī, in various dialects and languages often subsumed under the generic title ''Sant Bhasha'' or ''saint language'', in addition to other languages like Persian and various phases of Indo-Aryan languages. Modern Gurmukhī has thirty-five original letters, hence its common alternative term ''paintī'' or "the thirty-five," plus six additional consonants, nine vowel diacritics, two diacritics for nasal sounds, one diacritic that geminates consonants and three subscript characters.

ISO 15919
ISO 15919 (Transliteration of Devanagari and related Indic scripts into Latin characters) is one of a series of international standards for romanization by the International Organization for Standardization. It was published in 2001 and uses diacritics to map the much larger set of consonants and vowels in Brahmic and Nastaliq scripts to the Latin script. Overview Relation to other systems ISO 15919 is an international standard on the romanization of many Brahmic scripts, which was agreed upon in 2001 by a network of the national standards institutes of 157 countries. However, the Hunterian transliteration system is the "national system of romanization in India" and a United Nations expert group noted about ISO 15919 that "there is no evidence of the use of the system either in India or in international cartographic products." Another standard, United Nations Romanization Systems for Geographical Names (UNRSGN), was developed by the United Nations Group of Experts on Ge ...

Conjunct Consonant
Conjunct consonants are a type of letters, used for example in Brahmi or Brahmi derived modern scripts such as Balinese, Bengali, Devanagari, Gujarati, etc to write consonant clusters such as or . Although most of the time, letters are formed by using a simple consonant with the inherent value vowel "a" (as with "k" , pronounced "ka" in Brahmi), or by combining a consonant with an vowel in the form of a diacritic (as with "ki" in Brahmi), the usage of conjunct consonant permits the creation of more sophisticated sounds (as with "kya" , formed with the consonants k and y assembled vertically). Conjuncts are often used with loan words. Native words typically use the basic consonant and native speakers know to suppress the vowel. In modern Devanagari the components of a conjunct are written left to right when possible (when the first consonant has a vertical stem that can be removed at the right), whereas in Brahmi characters are joined vertically downwards. Some simple exampl ...

Virama
Virama ( ्) is a Sanskrit phonological concept to suppress the inherent vowel that otherwise occurs with every consonant letter, commonly used as a generic term for a codepoint in Unicode, representing either # halanta, hasanta or explicit virāma, a diacritic in many Brahmic scripts, including the Devanagari and Bengali–Assamese script, Bengali scripts, or # saṃyuktākṣara (Sanskrit: संयुक्ताक्षर) or implicit virama, a conjunct consonant or ligature. Unicode schemes of scripts writing Mainland Southeast Asia linguistic area, Mainland Southeast Asia languages, such as that of Burmese script and of Tibetan script, generally don't group the two functions together. Names The name is Sanskrit for "cessation, termination, end". As a Sanskrit word, it is used in place of several language-specific terms, such as: }, ''sukun'' , ް◌ , Derives from Arabic "sukun" , - , ''Srog med'' , Lhasa Tibetan, Tibetan , ''Srog med'' , ྄ , Only used when transcrib ...

Richard Sproat
Richard Sproat is a computational linguist currently working for Google as a researcher on text normalization and speech recognition. Linguistics Sproat graduated from Massachusetts Institute of Technology in 1985, under the supervision of Kenneth L. Hale. His PhD thesis is one of the earliest work that derives morphosyntactically complex forms from the module which produces the phonological form that realizes these morpho-syntactic expressions, one of the core ideas in Distributed Morphology. One of Sproat's main contributions to computational linguistics is in the field of text normalization, where his work with colleagues in 2001, ''Normalization of non-standard words'', was considered a seminal work in formalizing this component of speech synthesis Speech synthesis is the artificial production of human speech. A computer system used for this purpose is called a speech synthesizer, and can be implemented in software or hardware products. A text-to-speech (TTS) system c ...

Abugida
An abugida (, from Ge'ez language, Ge'ez: ), sometimes known as alphasyllabary, neosyllabary or pseudo-alphabet, is a segmental Writing systems#Segmental writing system, writing system in which consonant-vowel sequences are written as units; each unit is based on a consonant letter, and vowel notation is secondary. This contrasts with a full alphabet, in which vowels have status equal to consonants, and with an abjad, in which vowel marking is absent, Abjad#Impure abjads, partial, or optional (although in less formal contexts, all three types of script may be termed alphabets). The terms also contrast them with a syllabary, in which the symbols cannot be split into separate consonants and vowels. Related concepts were introduced independently in 1948 by James Germain Février (using the term ) and David Diringer (using the term ''semisyllabary''), then in 1959 by Fred Householder (introducing the term ''pseudo-alphabet''). The Ethiopian Semitic languages, Ethiopic term "abugi ...
