In the north-east quarter of the province, people in most cities and villages speak eitherChārmahāli (also in the Southwestern branch of Iranian) orChaharmahali Turkic. Chārmahāli is transitional betweenBakhtiari andPersian varieties ofIsfahan province, but more similar to the latter. Chārmahāli varieties spoken in cities include Dehkordi (inShahr-e Kord), Ghafarrokhi (inFarrokh Shahr), Heysheguni (inHafshejān), and Borujeni (inBorujen). There are also many other varieties of Chārmahāli spoken in rural areas.
Most types of Turkic spoken in this province are similar toQashqa'i ofFars province, but they are transitional to theĀzarbāyjāni (Azerbaijani) language of north-westIran. The Chārmahāli andTurkic language areas overlap with one another, and in the foothills of theZagros and in the larger cities, they intermingle with Bakhtiāri as well.[8]
Tehrani-type Persian is now being taught by parents to children as a first language in some parts of the province, with the highest concentrations in the cities.[8] This statistic is based on the population statistics of 2013.
