Kullui (Kullū, also known as Kulvi, Takri: 𑚊𑚰𑚥𑚷𑚱𑚃/𑚊𑚰𑚥𑚷𑚱𑚦𑚯) is a dialect of Himachali language spoken in the Kullu District of the Indian state of Himachal Pradesh.For the stops and affricates there is a four-way distinction in phonation between tenuis /p/, voiced /b/, aspirated /pʰ/ and breathy voiced /bʱ/ series.

/ɳ/, /ɭ/ and /ɽ/, together with their aspirated correlates, don't occur in the beginning of words.

[2] The glottal stop occurs only between a vowel and /ɳ/, /n/, /r/ or /l/, e.g. [kɑːʔɭ] "a trumpet", which contrasts with [kɑːɭ] "famine".

The pharyngeal fricative /ħ/ historically derives from /s/ and occurs word-finally, e.g. [ɡʱɑːħ] "grass", [biːħ] "twenty".

According to the United Nations Education, Scientific and Cultural Organisation (UNESCO), the language is of definitely endangered category, i.e. many Kulluvi children are not learning Kulluvi as their mother tongue any longer.
