Lamani language is counted essentially as an Indian tribal language, widely spoken by the scheduled tribes residing in the heartland of Orissa state. In addition, almost all the states of East India and also other states comprising Andhra Pradesh, Madhya Pradesh, Himachal Pradesh, Gujarat, Tamil Nadu, Maharashtra, Karnataka etc. You can learn these dialects only if you are closely associated with the tribes speaking this languages. Probably, there is no such school teaching such tribal dialects.
