Ban Khor Sign Language (BKSL; Thai: ภาษามือบ้านค้อ) is a village sign language used by at least 400 people of a rice-farming community in the village of Ban Khor in a remote area of Isan (northeastern Thailand). Known locally as pasa kidd ('language of the mute'), it developed in the 1930s due to a high number of deaf people. Estimated number of users in 2009 was 16 deaf and approximately 400 hearing out of 2741 villagers. It is a language isolate, independent of the other sign languages of Thailand such as Old Bangkok Sign Language and the national Thai Sign Language.
Thai Sign Language is increasingly exerting an influence on BKSL. Younger Deaf attend distant residential Deaf schools where they learn Thai Sign Language. Even middle-aged hearing people are using Thai SL vocabulary mixed with BKSL. Attitudes favoring Thai SL over BKSL are beginning to be expressed.
