Phonology and Scripts
The vowel system in Talyshi is more extended than standard Persian. The prominent differences is the front vowel ü in central and northern dialects and the central vowel ə. In 1929, a Latin-based alphabet was created for Talyshi in the Soviet Union. However in 1938 it was changed to Cyrillic-based, but it didn't gain extensive usage on variety of reasons, including political Stalinist consolidation of socialist nations. Nowadays, the Perso-Arabic script and Azeri Latin are also used in Iran and Azerbaijan respectively. The following tables contain the vowels and consonants used in Talyshi. The sounds of the letters on every row, pronounced in each language, may not correspond fully.
