Voiced bilabial plosive in the context of "Assimilation (phonology)"

The Persian alphabet (Persian: الفبای فارسی, romanized: Alefbâ-ye Fârsi), also known as the Perso-Arabic script, is the right-to-left alphabet used for the Persian language. It is largely identical to the Arabic script with four additional letters: پ چ ژ گ (the sounds 'g', 'zh', 'ch', and 'p', respectively), in addition to the obsolete ڤ that was used for the sound /β/. This letter is no longer used in Persian, as the [β]-sound changed to [b], e.g. archaic زڤان /zaβɑn/ > زبان /zæbɒn/ 'language'. Although the sound /β/ (ڤ) is written as "و" nowadays in Farsi (Dari-Parsi/New Persian), it is different to the Arabic /w/ (و) sound, which uses the same letter.

It was the basis of many Arabic-based scripts used in Central and South Asia. It is used for both Iranian and Dari: standard varieties of Persian; and is one of two official writing systems for the Persian language, alongside the Cyrillic-based Tajik alphabet.

In phonetics, a plosive, also known as an occlusive or simply a stop, is a pulmonic consonant in which the vocal tract is blocked so that all airflow ceases.

The occlusion may be made with the tongue tip or blade ([t], [d]), tongue body ([k], [ɡ]), lips ([p], [b]), or glottis ([ʔ]). Plosives contrast with nasals, where the vocal tract is blocked but airflow continues through the nose, as in /m/ and /n/, and with fricatives, where partial occlusion impedes but does not block airflow in the vocal tract.

In phonetics, a homorganic consonant (from Latin homo- 'same' and organ '[speech] organ') is a consonant sound that is articulated in the same place of articulation as another. For example, [p], [b] and [m] are homorganic consonants of one another since they share the bilabial place of articulation. Consonants that are not articulated in the same place are called heterorganic.

Beta (UK: /ˈbiːtə/, US: /ˈbeɪtə/ ; uppercase Β, lowercase β, or cursive ϐ; Ancient Greek: βῆτα, romanized: bē̂ta or Greek: βήτα, romanized: víta) is the second letter of the Greek alphabet. In the system of Greek numerals, it has a value of 2. In Ancient Greek, beta represented the voiced bilabial plosive IPA: [b]. In Modern Greek, it represents the voiced bilabial fricative IPA: [β] while IPA: [b] in borrowed words is instead commonly transcribed as μπ. Letters that arose from beta include the Roman letter ⟨B⟩ and the Cyrillic letters ⟨Б⟩ and ⟨В⟩.

Ve (ڤ) is a letter of the Arabic-based Comoro, Kurdish, Luri, Swahili, and Wakhi alphabets. It is derived from the Arabic letter fāʾ (ف) with two additional dots. It represents the sound /v/ in the aforementioned uses. On the other hand, the letter Pa (ڤ) represents the sound /p/ in the Jawi (used for Malay) and Pegon (used for Javanese) alphabets.

Ve originated as one of the new letters added for the Perso-Arabic alphabet to write New Persian, and it was used for the sound /β/. This letter is no longer used in Persian, as the [β]-sound changed to [b], e.g. archaic زڤان /zaβɑn/ > زبان /zæbɒn/ 'language'

Be (Б б; italics: Б б or Б б; italics: Б б) is a letter of the Cyrillic script. It commonly represents the voiced bilabial plosive /b/, like the English pronunciation of ⟨b⟩ in "ball". It should not be confused with the Cyrillic letter Ve (В в), which is shaped like Latin capital letter B but represents the voiced labiodental fricative /v/ or the voiced bilabial fricative /β/. The Cyrillic letter Б (Be) is romanized using the Latin letter B.
