An abugida – sometimes also called alphasyllabary, neosyllabary, or pseudo-alphabet – is a segmental writing system in which consonant–vowel sequences are written as units; each unit is based on a consonant letter, and vowel notation is secondary, similar to a diacritical mark. This contrasts with a full alphabet, in which vowels have status equal to consonants, and with a abjad, in which vowel marking is absent, partial, or optional – in less formal contexts, all three types of the script may be termed "alphabets". The terms also contrast them with a syllabary, in which a single symbol denotes the combination of one consonant and one vowel.
The Brahmic scripts, also known as Indic scripts, are a family of abugida writing systems. They are used throughout the Indian subcontinent, Southeast Asia and parts of East Asia. They are descended from the Brahmi script of ancient India and are used by various languages in several language families in South, East and Southeast Asia: Indo-Aryan, Dravidian, Tibeto-Burman, Mongolic, Austroasiatic, Austronesian, and Tai. They were also the source of the dictionary order (gojūon) of Japanese kana.
The Thai script is the abugida used to write Thai, Southern Thai and many other languages spoken in Thailand. The Thai alphabet itself has 44 consonant symbols and 16 vowel symbols that combine into at least 32 vowel forms and four tone diacritics to create characters mostly representing syllables.
The Burmese alphabet is an abugida used for writing Burmese. It is ultimately adapted from a Brahmic script, either the Kadamba or Pallava alphabet of South India. The Burmese alphabet is also used for the liturgical languages of Pali and Sanskrit.

The Ahom script or Tai Ahom Script is an abugida that is used to write the Ahom language, a dormant Tai language undergoing revival spoken by the Ahom people till the late 18th-century, who established the Ahom kingdom and ruled the eastern part of the Brahmaputra valley between the 13th and the 18th centuries. The old Ahom language today survives in the numerous manuscripts written in this script currently in institutional and private possession.

Lisu is a tonal Tibeto-Burman language spoken in Yunnan, Northern Burma (Myanmar) and Thailand and a small part of India. Along with Lipo, it is one of two languages of the Lisu people. Lisu has many dialects that originate from the country in which they live. Hua Lisu, Pai Lisu and Lu Shi Lisu dialects are spoken in China.

New Tai Lue script, also known as Xishuangbanna Dai and Simplified Tai Lue, is an abugida used to write the Tai Lü language. Developed in China in the 1950s, New Tai Lue is based on the traditional Tai Tham alphabet developed c. 1200. The government of China promoted the alphabet for use as a replacement for the older script; teaching the script was not mandatory, however, and as a result many are illiterate in New Tai Lue. In addition, communities in Burma, Laos, Thailand and Vietnam still use the Tai Tham alphabet.

Local people in Northern Thailand also call the script as Tua Mueang in parallel to Kam Mueang, a local name for Northern Thai language.

Burmese Braille is the braille alphabet of languages of Burma written in the Burmese script, including Burmese and Karen. Letters that may not seem at first glance to correspond to international norms are more recognizable when traditional romanization is considered. For example, သ s is rendered ⠹th, which is how it was romanized when Burmese Braille was developed ; similarly စ c and ဇ j as ⠎s and ⠵z.
